    This pack is super comfy. I used it for UTMF in ’15 and it worked great. plenty of stash pockets and easy access to layers in the back angled pockets for gear that you take on and off, like a waterproof jacket, without having to take the pack off. Love the quick loop bungie chords on the front too. Nice feature.

    So I have owned an Ultraspire race vest for 5 years now. I loved it but wanted a do all pack. So I checked around the site and settled on the Velocity. After receiving the pack I checked it out and loved my choice. It comes with two bottles that are a hard/soft version. It fits to the body just perfect. Yes you can hear water slosh, but come on it’s going to do that. If you don’t like that get Ultraspires soft flasks that will shrink as you drink. One of the reasons I bought this was for Long run/ Adventure runs. You can fit 4 bottles on the pack. The bottles that come with the pack will fit in the back pockets. They are not easy to get to but for long runs you can take off the pack and switch the bottles out. The other sweet part it has a area for a two litter hydration bladder. That’s alot of water. Sure it is heavy but your running a training run or an epic adventure run so man up and get r done. So after all the water is in you still have a nice size compartment to fit anything and everything. There is also a small pocket that zips to fit smaller items, I use it for my cell phone. I also put my phone up front with the bottle for easy access. The small pockets up front are good for small things, keys ect. So to the fit, wow it is snug and I love it. The pack has the Dual Max O2 Sternum straps and they work great. You are able to breathe easy and the pack does not move around. So there it is, I have used it for a quick 6 with nothing but one bottle in it to a long run with a bladder and two bottles. I will use this for my three planned 100 mile runs this year. Perfect do it all Pack!!!

    Participated in a little race this past Friday. Ran 107-ish miles, climbing 33,000+ feet in the beautiful mountains of north Georgia. The Cruel Jewel is one heck of a race and I highly recommend it if you want a good challenge. I used the my new VELOCITY pack and it was ideal! It worked GREAT! Extremely comfortable and highly breathable. I also used the Lumen 600 waist lamp, in conjunction with a headlamp. Talk about light-power! I pushed through to a 4th place overall and 1st place age 40-49 — 27h 20m 03s. The VELOCITY is just brilliant!

    I was looking for a smaller race vest (mine was 11L) and one that would carry round or flask style bottles. (I dislike the body bottles) And with the option for a reservoir and the ability to carry folded trek poles this vest fit my needs. As the reservoir drains down I can adjust the fit on the fly which really helps as the day goes on. I found the bottles can sometimes get stuck in the pockets but not a that big of a deal to wiggle them out as the pocket seems a bit too tall for the Aspire flask bottle. All in all a nice semi-minimalist vest.
