What Our Gearhead(R) Experts Are Saying:"I started using the Body Bottle 150G on long training runs where I wanted gels on hand without the wrapper mess, and it totally changed my nutrition routine. It holds five servings, shrinks down as I go, and when it's empty, I barely know it's there."Long miles have a way of making every ounce count, and nutrition is one place where smart runners refuse to compromise. The Ultimate Direction Body Bottle 150G solves the age-old problem of fumbling with wrappers mid-stride, letting you pre-load your gels, electrolytes, or custom nutrition mix into one squeezable, packable flask that plays nicely with any vest or shorts pocket. The 28mm opening makes filling and cleaning a no-effort task before the run, and the TPU construction is tough enough to absorb the daily abuse of training life. As you work through your fuel, the flask shrinks with you, eliminating the annoying slosh that comes with a half-empty container. When the miles are done, it collapses down to almost nothing and disappears into your pack until the next adventure calls.
