The updated UltrAspire Kinetic packs 2 rear ergonomic holsters with 26 oz bottles via a lightweight race vest shape with several pockets to stash all your nutrition, small essentials and a shell jacket. A unique rear strap holds the Kinetic close to the body without inhibiting natural motion; front sternum and waist compression straps help secure the ride as the contoured vest shape evenly distributes weight to eliminate pressure points. A front magnetic pocket stores electrolyte capsules to keep you running multiple hours.

Customer Reviews

Comments: I bought this for relatively short runs (3-4 hours) because I prefer bottles to bladder when possible and in that regard, it didn't disappoint. I don't love the belt though because it hits me in an odd spot, although I do like the storage provided on it. I've also had some problems getting this to fit in a way that is not too tight across the chest, but doesn't slip on my shoulders. Last, the hook on the belt is rather difficult to insert into and remove from the corresponding loop on the other part of the belt. I think the quality is fine, but I'm not sure I would buy this again for the reasons stated.

Comments: The bottles I didn't really like too much. They leak and the top pops off easily. I replaced them with some camelbak bottles and they worked much better. The vest is good and adds a great deal of hydration for ultra races. I just wish they would improve on the poor quality bottles.
