UltrAspire 800ml Softflask w/bite cap

$59.99

The UltrAspire 800ml Softflask is a collapsible running flask with a silicone sheath bite valve. It carries 800mL and squashes down as you drink, so it stays put in a vest pocket instead of sloshing. The larger top is wide enough for ice cubes, handy on a hot summer long run. Pair it with a smaller flask when you need to carry electrolytes as well as water.

Collapses as you drink, so less slosh
Shaped to slide in and out of a vest pocket easily
Wide top takes ice cubes to keep fluid cool
Bite valve lets you sip without unscrewing anything
Pairs with a smaller flask for water plus electrolytes

Capacity: 800mL
Valve: Silicone Sheath bite valve
Material: PVC and BPA free
Design: Collapsible
Pairs with: 300mL UltrAspire Softflask

Long runs and ultras in a vest with front flask pockets
Hot days where ice in the bottle makes a difference
Runners carrying a second flask for electrolytes

Less suited to: carrying fluid on a hose rather than in a flask. For that, look at Hydration.

Soft flasks beat hard bottles in a vest because they shrink as you drink. This one holds a decent 800mL and the wide top makes filling and icing simple. It is also the flask the Bloddle hose attachment is built for.
