Hydrapak unveiled two new soft flasks this week, the .35 liter (12 ounce) SF350 and the .5 liter (16 ounce) SF 500 which instantly won ISPO’s Performance Accessories category.  Expanding on the already successful five and eight ounce soft flasks,  these add versatility via a larger filling port,  shut off valve, and optional hand strap.  The larger capacity also adds a little extra utility as they are designed to deliver liquid, gel, or a mix of the two and will surely fit nicely in a jersey pocket .   The SF350 and 500 won’t be available to the public until summer and will range in price between $15 and $25.


  1. Haha 16 oz of gel seems a lil gross, 12 maybe. But even keeping the 12 2/3 full is better than trying to bite open clif blocks and getting gu on your fingers. And the no wrapper deal is great.

What do you think?
