Nathan Men's Speedster 2L Hydration Vest (Turkish Sea, Small)

I used this for the first time on a 20-mile long run. I live in a not-so-flat, often humid climate so hydration is very important on long runs. This vest is very light weight, unobtrusive, and hardly noticeable. The 12 oz hydration bottle collapses as you drink from it. And what is best about it is how you can sip and not stop running. There no bottle to awkwardly put back in a holster or anything like that. I only wish it came with two but I was able to find one made by the manufacturer and purchase it. Lastly, I would recommend rinsing it off after each run as it does absorb sweat.

Super comfortable, I’ve never had any chafing even without a shirt on. Front pocket fits 1 water skin on one side and my iPhone 7+ In the other . I use smaller front pockets for Gu’s.
