[This review was collected as part of a promotion.] This running vest performed excellent during a recent 50 mile trail ultra I competed in. The course was many miles of single track, gravel, hard pack dirt, sand, rocky sections, and 3 creek crossings, with total elevation gain +11,000 feet. The design of the vest is really top tier. The fit is excellent and pocket placement makes sense. When I run with this vest I don't think about it all- I don't get hot spots, there's minimal to no bounce, I can access my gear anywhere on the vest without issue. Would absolutely recommend.
185cm 37cm chest 55cm torso Hopefully this will help someone who is on the borderline of sizes. The photos show the small on top of the medium. There is not that much difference in length and width between the two but I find on my body there is greater armpit clearance on the medium with the small sitting to high. I do have a fairly long torso though. As for fit ? It's difficult to tell as I can only test them in the living room before returning one. The small feels secure but rides too high and the medium feels better but needs to be cinched very tight. I may have to just accept this vest doesn't fit my body. The front pockets are great and easy to access and the inner back panel seems very smooth. I actually chose this vest as I hike in merino wool tees and this vest looks like the least abrasive available currently ... only time will tell with the t-shirt wear and tear.
