Hammer down.

Given the option of keeping five Hammer Gel packs in our jersey pockets to tear open with our teeth one by one, or keeping the contents in a dedicated receptacle like the Hammer Nutrition Flask, we'd choose the latter. The Nutrition Flask holds five Gel servings, and features a thick construction that's compatible with Hammer's bike holders. The flask also uses both a molded fingertip design, and a hygienic, secure cap, that allows you to hammer down your gel—all puns intended.

The Hammer Nutrition Flask is available in the color White, and holds five servings of Hammer Gel.

  • Familiarity: I've used it several times

I made the DIY energy gels according to the post in the Articles section, and this is the container I use to inject the energy-gooiness into my gullet. Great size, 5oz is plenty of room, nice squeeze to it, cap is easy to manage, and fits well in a cycling jersey pocket.

great product

  • Familiarity: I've put it through the wringer

Less litter at races. No sticky mess in jersey pockets. Carries enough for long rides.

Not only do these save money, as others have pointed out, and carry five servings, they do it without the what the heck do I do with this sticky mess of an empty gel packet problem. That's where the real money is. Oh, and the Montana Huckleberry is WIN.

These little guys work great

  • Familiarity: I've put it through the wringer

I use this with my camelbak and other packs I have for riding. Works great.

These are not the same as getting a pack of FSA prepacked gu flasks. Those are much thinner and I can see being used a couple times but this is a much heavier material made to last.

Save $$

  • Familiarity: I've put it through the wringer

These are great containers to fill up with gel. Saves lots of mula and you can carry enough for looong rides!

Reuse the bottle and save some money on gel.
