UltrAspire’s low profile, award winning trail racing pack just got better with the Alpha V3.0 edition.
The Alpha hugs your body and holds your long run essentials, kind of like the ultimate support crew. Up front, the minimalist but effective elastic closure keeps the vest stable against your torso, so it won’t bounce on downhills or fast flat stretches. There are lots of quick access pockets for your water, fuel, headlamp and jacket, plus a sweat-proof pocket so your electrolyte tabs don’t crumble.
While the Alpha V3.0 includes x2 550ml UltraFlask Bottles the pack includes a secure internal bladder sleeve that rides low and unnoticed in the small of your back, and is easy to open for smooth, fast refills at aid stations if your preference is a hydration bladder.
