Comments about Hammer Nutrition Hammer Gel Flask:
This versatile little bottle can be used for energy gel, meal replacement drinks, energy drinks and water too. Fits great in cycling jerseys and running jackets. Quality seems good, doesn't feel like cheap bottle that tend to crack and tear over time. I use it on longer rides so I don't have to bring several energy gels with me. Don't have to worry about making a mess or getting rid of the wrappers. I would highly recommend this product!
