    1. Happier with SJ 3.0

      I've used the PB 2.0 for a variety of training runs and races from 10 miles to 50K. I'm happy to say the SJ 3.0 will likely be its replacement. I was hesitant when I saw the 3.0 wasn't going to come in an XL but the dimensions for the L are almost identical if not a bit bigger. The materials seem to be of a high quality in the 3.0 SJ. The vest is lighter than my PB 2.0 and I like the stretch of the pockets to stash small items securely. The loops for stowing trek poles are in a much more convenient place although I don't use poles - it is handy for my GoPro stick though. I think the fit can be dialed in a bit more since the side straps replace physical pockets the PB had. The PB 2.0 side pockets were always hard to zip or unzip. The soft bottles I haven't used much but I like the idea. I liked the hard bottles because they were quick to fill and I had 4 of them. I could carry 2 and have 2 waiting at aid stations or with crew to swap out. If the soft bottles work well I'll just buy a couple more. I do like the colors more on the 3.0 version of all the hydration packs. Just personal preference but I'm glad the blue is a darker blue, there's some black and white too instead of the previous grey and baby blue/white. Lastly, customer service actually made an effort to communicate with me about sizing and ordering - I like a company that's willing to make sure customers are happy. I'd still maybe like to see an XL in the PB 3.0 vest and more XL in UD outerwear but I think supply and demand will help that along. All in all. Dry pleased with UD after not starting out so happy. Keep runners running! on Mar 23rd 2016

    2. Super comfortable!

      I've run Ultras for a couple of years now, and have tried every type of hydration system out there (e.g. handheld, bladder vest, waist belt, etc.). I feel that each has it's own place depending on the situation. I always see 100's of UD vest at every race, and I decided recently to give them a shot. When I saw the v3.0's were coming out I waited, and Oh boy...Was it worth it!....I think I have found the one hydration system "to rule them all".

      PROs: The vest is CRAZY comfortable - light, soft, flexible, very breathable! Plenty of storage that is FULLY accessible while running. Lots of adjustment to customize the fit for each person or adjust to larger loads as needed. Trekking pole holders keep the poles secured and at the ready at all times.

      CONs: I'm not a fan of the soft bottles because they 1) collapse and fall into the pockets as they empty, and 2) have smaller mouths making the addition of powders harder. However, that is a minor gripe because the hard bottles fit just fine are are not uncomfortable! The only design issue I have is the potential longevity of the pole holders. I feel the elastic loops will wear out over time. A better idea might be a small buckle (like the chest strap) and a cinch.

      Overall - I'm pretty sure every other hydration system I have is now obsolete!

    3. Love this vest

      I purchased this hydration pack recently and it has become my new favorite pack for my long runs. The soft water bottles make them easy to stash once their empty, without having to find a spot for a big bulky water bottle. The accessory pockets are perfect. I've got a spot for my car key, phone, and extra space for whatever foods or gels I am carrying with me that day. on Mar 18th 2016
