Hydrapak Ultra Flask

500ml: Part of our ultra-light series, the 500ml is so light, you might forget you brought it. Weighing in at just over an ounce, it’s optimal hydration, no matter what kind of runner you are. Its pliable material conforms to most pockets, it shrinks as you drink to minimise water movement and it can be used with or without the tube. Ultra light weight, ultra useful.

Features

  • The UltraFlask makes a great hydration addition or replacement to your running vest, pack, or belt pocket
  • Vest-pack fit provides bounce-free stability and a flexible flask shoulder to prevent chafing so you can focus on FKT's and PR's
  • High-flow bite valve auto-seals after each sip, eliminating annoying drips
  • Large standard 42mm opening lets you fill the UltraFlask easily with ice and drink mixes
  • Customise your cap with two options depending on your run or vest, directly mount your bite valve or use the straw cap (which can be cut to any length)
  • Made of ultra-durable, abrasion resistant TPU & RF welded seams for superior durability and elasticity
  • Can be frozen or filled with hot water (max temp 60° C / 140° F)
  • Safe and reliable, 100% BPA & PVC free, top-rack dishwasher safe

600ml: Go big. The largest of our ultra-light series, the UltraFlask 600ml holds more so you can go the distance. Its soft material allows it to fit snugly in most vest pockets and it shrinks as you drink to minimise water movement.
