VaporAir Lite 4 Liter Hydration Vest

Runs small, runs great!

I am thoroughly happy with my vest. I combine the 2L bladder with 2 600mL soft bottles in the front pockets and I'm good to go for my training. Hydration for marathon training is harder than hydration during the actual marathon. I am a size 48 in the chest and the straps are VERY tight, even let all the way out. It would not be difficult for Nathan to make an extender kit with the same nylon strap material and clips.

This vest looks good

I bought this vest for my son boy we haven't used it yet. It looks like it will work well with the 2L bladder and pockets for other things. Also I like the ability to make adjustments for proper fit.
