Top to bottom, this is our lowest profile flask. It slips right into the snuggest run belts and leanest vest pockets. The new 28mm locking cap easily opens and closes with a touch of a thumb, preventing leaks and drips while in motion. Made for minimal distraction, the innovative pinch-welded bottom gives it a tapered profile and the low-diameter cap makes it comfortable to carry — no pokes or irritation.

Features:

  • MADE FOR FIT: Ultra low profile flask and minimal cap design are specifically designed for the snuggest running belts and leanest vest pockets.
  • HIGH FLOW: Easy to drink bite valve auto-seals after each sip, eliminating annoying drips.
  • LOCKING CAP: 28mm locking cap easily opens and closes with a touch of the thumb, preventing leaks and drips.
  • COMPRESSIBLE: Flexible design shrinks as you drink, minimizing water movement.
  • DURABLE: Made of ultra-durable, abrasion resistant TPU & RF welded seams for superior durability and elasticity.
  • 100% BPA & PVC FREE: Wide working temperature range (can be frozen - max temp 60° C / 140° F).
