Nathan created the Woman's Intensity Race Vest to fit your body instead of his, because running thirty miles in a race vest designed for a guy is a guaranteed ticket to pain. Nathan updated this ultra style running vest since last year, shaving a few ounces off the weight by using lighter materials and a lighter weight fabrication process throughout. Contoured shoulder straps and a redesigned waist belt match shape of a female runner's physique so this pack sits snug against your body. Weight savings and comfort are imperative for anything you're carrying in a distance event, so the Intensity uses an all mesh harness that's soft, feather light, and highly breathable. Simple and secure, a pair of side adjustments and a quick clip chest strap make for easy on and off at aid stations and allow you to dial in the fit of the vest on the fly. A hand held or a waist belt will keep you minimally supplied, but the Intensity can hold up to two liters of water, offer it up hands free through a hydration tube at your shoulder, and keep a light rain shell or nutrition within easy reach. Sometimes there's nothing like a running vest with a little extra storage.
