Sunmin Leewrote a review of Nathan VaporZach 2.5L Hydration Vest on January 19, 2020
It's practical design features light weight! When worn, it sticks to the body like socks. I look forward to 2020 with this product.
Size Advice: I'm 5'8" and chest is 34.5 inches, I bought an XS size, but I think S size would be better. Anyway, this product is the best!
