### ⭐⭐⭐⭐⭐ 







  
  
    Great for Backpacking
  

*by R***R on Reviewed in the United States on 20 October 2023*

Hands free drinking at its best!  This was a game changer on my recent back packing trip!  I use trekking poles and always hated having to do something with the poles just to try to drink my water.  This was perfect!  I purchased a strap pouch, so it road right on my left chest and was in reach for my sipping as I was hiking.  Easy to fill and easy clean.

J’ai acheté cette gourde pour remplacer une de Raidlight et j’apprécie le mécanisme de pouvoir ouvrir pour remplir sans dévisser. Bonne qualité
