VEST COMPATIBLE HYDRATION

Go big. The largest of our ultra-light series, the UltraFlask 600 ml 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 minimize water movement.


  • COMFORTABLE FIT
    Soft material conforms to most hydration vests, belts, or pack pockets
  • COMPRESSIBLE
    Flexible design shrinks as you drink reducing water movement
  • MULTI CAP
    Includes a bite valve cap and an adjustable drink tube cap


Features

  1. A great hydration addition or replacement to your running vest, pack, or belt pocket
  2. 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
  3. High-flow bite valve auto-seals after each sip, eliminating annoying drips
  4. Large standard 42mm opening lets you fill the UltraFlask easily with ice and drink mixes
  5. Customize your cap with two options depending on your run or vest, directly mount your bite valve or use the straw cap (4 in / 100 mm)
  6. Made of ultra-durable, abrasion resistant TPU & RF welded seams for superior durability and elasticity
  7. 100% BPA & PVC free, wide working temperature range (can be frozen - max temp 60° C / 140° F)
