The SF250 Collapsible flask is a highly collapsible energy gel and drinks flask with a spill-proof and self sealing bite valve. Clean, compact and easy to use.   

Hydrapak says:

Nutrition on demand, the SF250 Collapsible Gel Flask can be integrated into a variety of packs, vests, PFDs, and lumbar belts.

Lightweight, flexible, and easy to squeeze the SoftFlask™ collapses as you drink. Eat as much as you wish per use and throw in the fridge for later. The patented, spill-proof, self-sealing, bite-valve is easy to use and completely removes for cleaning. Designed to carry gels, water, electrolytes, or your own nutrition concoctions.

The Hydrapak's SF250 Collapsible flask is much more convenient for carrying your energy gels in as the soft flask collapses as you drink, making sure you get every last ounce out. It also means it's a lot easier to store in small pockets when it's empty.

It can hold around 8 gel servings and the spill-proof bite valve will make sure you don't waist any of it.
