    Wore for my first 100 Mile, the Black Hills 100. and it worked great. One bottle for Electrolyt and calories and the other for water. Much easier on my upper body than camelbak. Reason don't give it 4 stars is due to the bottle shaking up front...Really nothing you can do about. Just something to get used to on runs.I did purchase a bladder for it that I have yet to use.

    Absolutely thrilled with the SJ Ultra Vest 2.0. Easily adjusts to fit me perfectly. Plenty of storage... It seems every time I think "I wish there's a pocket right here" I find there is! I'm certain I haven't found all of them. I'm new to having the bottles up front but it was easy to get used to in a few miles and so much easier than a bladder. I did switch out the kicker caps for my regular old school type, they fit the 20 oz bottles. I may put a kicker back on one to get used to them over time. Overall I'm a very happy runner with the SJ Ultra Vest 2.0. Great work UD!

    I am 5'11 and 170. I got the large and it fits awesome. I found the adjustment straps to adjust very easily on the go. I like to adjust a little between ascents and descents. The bottles held great in the front pockets. However, I could not stand to listen to the water jostling around in the bottles. So I bought two body bottles (soft flask) when I bought the vest. They are so much better. There is little to no air when you use them, so sloshing is next to none. They also compress down to almost nothing when empty. I just wish those soft flasks where about 3-4 oz. larger. I carry an extra bottle in the back and and holds great. Highly recommend this vest w/the flasks. Keep up the awesome work UD!!!! The only reason I gave a 4 instead of a 5 is I would like to see the vest come with the soft flasks.

    I received my SJ Ultra Vest 2.0 on Friday. I picked up the box at the door and wondered if anything was in it, this vest is super light. I took it for a 2:15 run yesterday in the Franklin Mountains. It was a cool day but even on a hot day I don't think the vest will add much heat, it is vented in every possible place. The only time I experienced bounce was when I ran down into arroyos, but that is probably due to the fact that I bounce a bit getting over the rocks and exposed rock face. I was also concerned about sloshing and the vest becoming unbalanced. There was some sloshing noise but I didn't notice it after the first half mile its no worse then a hydration bladder, I found myself self drinking from the left side bottle and it never became noticeably unbalanced. The only other thing I carried was a small phone which didn't fit in the pocket above the water bottle but it never fell out and I will just relocate it to another larger pocket, there are a ton of them to pick from. It's a great vest and exactly what I was looking for and most of my concerns, excess heat, bounce, and getting unbalanced were not an issue.

    I'm 5'10 165lbs 30-31 waist and wear a 38R jacket. I do have broad shoulders and an athletic build. I opted for the Large sized based on the recommendations. I would advise anyone to try it in a store if possible. I found that the Large, even when everything was cinched down to the smallest chest adjustments was just a tad loose. Luckily the new side adjustments were there and I was able to dial the fit in. I have tried the old version in a Large and it was too loose. But these new side adjustments did help a lot and made the fit snug and have very little bounce during my runs. I like to have the bottles in the front as parallel as possible, less than 6 inches apart, and maybe a 5-10 degree angle. some people wear it way too far apart and complain about not being able to access the bottom front pockets. You do have to load the pack properly to distribute the weight with full bottles in the front. but once I got everything organized as far as packing and the fit right, running with the vest was great. I could still feel some weight in the front due to the filled bottles, but it wasn't an inconvenience to my run. I did take it out for a test run on 5 miles of trail... I ran it shirtless, just wearing the vest and I did get some chafing issues on my nipples turns the end of my run. But I did run 5 miles on the road with a shirt on with no issues at all. I do love the additional pocket for the bladder and being able to run the line going from the bottom up. This is just going to be my go for when I go on my runs... just having so many pockets is a blessing. I have a Samsung Note 3 cell phone and the best place for me to put it in the vest is in the small back pocket. or one of the side pockets, but its a bit awkward, but the back is the best. using the front bottle pockets was a no go for my phone. I do wish there was a AK vest with the small side pockets in the back and the side elastic pouch on the front bottle holders... That would have been my idea vest.

    This vest is super on storage capabilities. It would even make a great day hike pack for me! I am 5'-10", 38R sport coat, 155lbs, 32" waist pants, and run a medium in most torso sized hiking packs. I bought the medium, and it fits great with room for thicker clothing. It will also cinch down pretty snug. Yeah, the bottles slosh, but so does your handheld when you run with it?!?! It was not an issue with me. Pack rides great with little to no bounce if you load it properly. The body bottles have no noise and are super comfy with these packs. I ran a 2 hour half mary trail training run in it to test it out. I had one body bottle, one UD supplied bottle, honey stinger waffle, pocketfuel natural, and a gel on the front storage. In the back I had a Northface better than naked jacket. Pack rode awesome. Some condensation did build up in the "bladder" pocket, but you are out there running, sweating, and being great. This was not a big deal to me. This is a great pack for the super long, unsupported trail day or the 100 that is in my near future. I'll turn to the AK vest for 50k and under with a Jurek essentials belt if needed.

    The Jurek Vest has been an ideal item for me on long runs and ultras. I love using it for long training runs in the cold when I need to carry a jacket and fuel, and it was a key gear item for me in the Leadville 100 run.

    I have used the vest a few times now with mixed results in runs up to 20 miles, or about 3 hours.. My two complaints are that 1) I can't get fluid out of the two bottles that were supplied, and 2), the vest bouces considerably when the bottles are used in front, creating a very heavy vest. I have found that if carry one bottle in my hand, it is enough to reduce the bouce, even if the other bottle is full. Maybe someone can provide feedback about why my two bottles seem clogged. (UPDATE) After reading my review, a staffer from UD contacted me and gave me some tips for better usage of both the vest and bottles. Both of his tips were spot on. The vest no longer bounces, and the bottles are fully functional. (Thank you, Justin). I'll be putting it to the test again this weekend in a mostly muddy 50-miler! I read and write a lot of reviews. Very few companies pay attention to what is written in reviews of their products and services, but I appreciate that UD does! Fantastic, friendly customer service. I'll be back to this site when I need additional gear in the future.

    I love this vest!!! I was using a Camelbak and after years of use and washing, it leaked and never had the right amount of space I need for keys, phone, tissues, etc. I love the fact that this vest comes is so many sizes. I had at first ordered the wrong size and after talking to U.D., I was able to trade it quickly and easily. Thank you for having such great customer service. I will definitely buy something else with your company again!

    I received my vest the night before a medium length 3 hour run. I was pretty excited and filled the 2 20oz bottles that came with it, fit several different brands of gels in the 2 pockets next to the bottles, in the two pockets under the bag in back on the waste belt area i fit in one side a small first aid kit and small pack of kleenex, and small bag of Valentines candy. The other side waste band pocket, a ziplocked iphone5, a big protein bar, and extra space, in the large rear main compartment i first put my down OR Transcend jacket(replaced it with a Salomon Momentum jacket instead), in the other of the three sections in the large compartment i fit a face ice shield, a beanie, a fleece ear warmer band, there would have easily been room for my Cammelback bladder in the third compartment. It felt balanced loaded this way. I am 6 foot 3 145lbs 33 inch chest. (Probably suck in air before measuring ) i ordered a medium and the chest straps are adjusted on top almost all the way tight and the bottom 3 inches out. The internal adjustment i pulled in an inch on each side. I was running where the Ultra Buffalo Run takes place (Antelope Island Utah). The conditions were Slush, Ice, mud, High winds. This was my first bottle forward pack, it took about 2 miles to stop thinking about it before i forgot it was on. My other hydration pack was a customized Cammelback pack ( that rubs my shoulders ) or my Cammelback waist flask belt. Overall i can honestly say i forgot i had it on until it started being really windy and i took it off to pull the jacket out. I drank the bottles one at a time and it didn't change its balance. When i got back there was condensation in the top of the main compartment, because of this i would ziplock things that aren't waterproof. I The construction seems strong and I am extremely satisfied with the pack. The only thing i would change is add a front iphone compartment above the water bottle. I will probably sew a waterproof one on. Nothings ever perfect because everyones expectations and uses are different.

    Lately I’ve realized that there are times when there are runs that fit somewhere in between those shorter runs and all day outings that seem to becoming a regular part of my training. Runs lasting between 2-6 hours seem to pop up on my calendar more and more, as do races where aid stations are spaced pretty far apart (relative to road marathons The first thing I noticed was that two bottles were included. This is important since the pack doesn't come with a bladder. The second thing I noticed was how short the vest was. I laid it side by side with the S-Lab 12 for comparison. The short length gives it a nice light & airy feeling, which translates over while running. Stash Pockets I was giddy at the prospect of being able to carry tons of nutrition up front. The pockets under the holsters fit granola bars and pocket knives perfectly. There are two grey mesh stash pockets above the bottle holsters that stretch to accommodate smaller cellphones, but not iPhones, MotoX or Galaxy S3/S4.That means if you run with your cellphone you will either need to stash it in the back or give up a front bottle holster so it can stash within easy reach. Lots of people carry phones when running (either for calls or for picture taking). It’s hard to believe zero of the eight pockets were large enough to hold a smartphone. Sides There are two pockets on each side of the vest. One ozips closed and one is open with a small piece of Velcro at the rim. These side pockets are large enough to accommodate an iPhone, a SteriPen, a small headlight or gloves. They are not large enough to hold visor, ball cap or say, Kahtoola Microspikes, which I carry in my S-Lab side pockets during spring on Rainier. Materials Soft edges, clean stitching and straps that stay cinched and don’t come loose make this a solid piece of gear. Fit I’m 5’8”, 150 with a 36-inch chest and a medium fit me well. This pack has straps under each arm that provide enough adjustment to make sure the front chest straps don’t bottom out. They side straps are hard to adjust while wearing the pack and I found myself taking the pack off to make these changes, which was no biggie. I was just a little bummed because the YouTube video looked like they were accessible while running. Also, the Nathan HPL has side straps that are easily adjusted while running. I don’t like stopping. With the SJ 2.0 I had to. The two bottles that come with the pack felt like they were teeter-tottering on my chest the way they are placed and caused the front of the vest to lift away from my body slightly. Salomon has a triangle bottle that fits the S-Lab 12 chest holster and it sits flat against the body, which is a feature I wish UD had incorporated. I fixed this by using a 20-ounce Hydrapak collapsible bottle I found at REI. Loading the vest I was so excited to load this pack up. I put a gel in every single vertical stash pocket I could find. I put a Larabar and a medium sized pocketknife in the two horizontal pockets under the bottle holsters. Since I carry a phone when running I removed one bottle in favor of using the holster to stash my cell. There was still plenty of space left in the holster where my phone was so I added an 8-ounce softflask with Perpetuem and a gel as well. Run Firstly, in my excitement I inadvertently front-loaded the vest way too much with hydration and food. It felt unbalanced. I moved my flask and some food to the back. Once I did that the vest felt fine. A little longer into the run I wanted to cinch the vest down even more, so I stopped and adjusted the side straps to snug it in a bit. This was perfect. The vest often times was hardly noticeable. Often times I would find myself not thinking of the vest at all, which is the way it should be. I swapped the UD plastic bottle with a collapsible bottle from HydraPak. It’s essentially the same material used by Softflask and the bladders made by HydraPak for Nathan. This improved the fit and feel up front since the bottle conforms to the shape of your body. On a long test run (15 miles on a dry 43 degree day) I noticed condensation build-up in the middle compartment of the rear. Any clothes or items that you want to be dry should either be placed in a zip lock when stored there or kept in another pocket. The smaller outside pocket in the rear (intended to hold smaller items) didn't get damp. Summary I like this pack. Its design is simple, well thought out, efficient and practical. This vest will most likely be my go to piece for supported ultras, all day summer runs where weather is not a concern. For carrying a cellphone I’ll just continue doing what I do now with my S–Lab and put the phone in one of the bottle holsters up front. I wish there was an easy spot to carry a visor snugly. If those two things could be fixed it would be near perfect.
