Softflask 500ml Water Bottle

What Our Gearhead® Experts Are Saying:

"This little flask has become my go-to for runs—it’s light, easy to refill, and doesn’t slosh once it starts to empty. The bite valve never leaks, and I love that it fits gels or electrolytes just as well as water. Super versatile and durable for how minimal it is."

We stay light and fast with the Rab Softflask 500ml Water Bottle, a flexible hydration solution that adapts as we move. Made from durable TPU with welded seams, it shrinks as we sip, reducing bounce and stowing flat in a vest, belt, or pack pocket once empty.

Designed for more than just water, the Softflask handles electrolytes, gels, or custom mixes with ease. The bite valve self-seals after every sip to prevent leaks, and the wide 42mm opening makes refills quick and hassle-free on the trail. At just 40 grams, it’s barely noticeable until we need it—and with freeze-friendly construction and heat tolerance up to 60°C, it’s versatile enough for every season. Free from BPA and PVC, it’s built for clean, reliable hydration wherever the adventure takes us.
