Review on 🎒 Nathan QuickStart Hydration Vest Pack - 6L Capacity, Includes 1.5L Bladder. Universally Applicable Size. Unisex Backpack for Enhanced SEO. by Justin Peck

I'm happy with the bladder and mouthpiece. The construction feels solid and there were no leaks during my test runs. (22 miles and 8 miles). I find the fit comfortable and haven't noticed any water rebound. I'm pleasantly surprised. The pockets are handy - I'm glad I don't have to carry a bottle in my hand. Tip: Put ice in your bladder on a hot day. It cools body and water. I'll be taking it for a full marathon in a few days - I'll review and edit if I find any errors.
