SFuels soft flasks are your answer for storing concentrated SFuels RACE+ on your run, to fuel your strongest finishes yet.
Pre-load SFuels soft-flasks with SFuels Race+ and water to make a concentrated fuel (see our SFuels Optimization Guide - pages 18-19) and pop it into the back of your race-suit or race-pack. For longer races, pre-load 1 soft flask with Race+/water for ready-to-go fuel, and then store a second SFuels soft flask ONLY with Race+ powder (i.e. no water). Add water (from aid-station) to this second soft flask, after finishing your first soft flask.
Using BPA-free materials and our Quick-Bite easy flow drinking nipple, the SFuels soft flasks provide a super-light flask with easy access to your favorite SFuels Race+ fuel flavors.
Size/Quantity: 10 ounce capacity.
