It's my new fave
[This review was collected as part of a promotion.] I've used lots of different running vests/belts/flasks in the past but this is my new go-to. It was comfortable on runs carrying as much as 3L of water + gels, phone, and food. It breathes surprisingly well despite the surface area it covers. The vest is wonderfully form-fitting and adjustable with the chest straps and elastic toggles.
Outstanding Vest!
I purchased this vest to prepare for and use during my half-marathon. The vest is very comfortable and was easy to set up and use with plenty of room for my gear.
