USWE Ultraflask 0.5L Transparent, One Size

"What Our Gearhead® Experts Are Saying:""These flasks have become my go-to for long training runs. The extended tube makes it super easy to sip without breaking stride, and the TPU holds up to cold mornings and hot mixes without deforming. They slide perfectly into the front pockets of my running vest and never feel sloshy.""We grab the USWE Ultraflask 0. 5L when we want reliable, lightweight hydration that keeps pace with long runs, big climbs, and all-day efforts. Made from ultra-durable TPU with RF-welded seams, this soft flask handles everything from gel mixes to ice-cold water, and even warm fluids on colder days. Its flexible body compresses as we drink, reducing bounce and keeping the carry smooth and stable from mile one to mile twenty. The extended drink tube and bite valve let us sip on the move without slowing down, pairing perfectly with USWE running vests like the Pace series. Whether we’re pushing through an ultra, stacking training miles, or heading out for a fast lunchtime loop, this flask keeps hydration simple, efficient, and always within reach."
