Review: Muy buena - Muy funcional y de buen tamaño
Review: Buy it!!! - This is a great backpack! Super happy with it. It’s very comfortable and has tonnes of space and pockets. I really like how there’s a built in rain cover (haven’t had to use it yet). I initially thought the water bladder was faulty because it leaked where the straw connected, but it just wasn’t tightened enough! So make sure it’s fully fastened before you head out!

## Questions & Answers

**Q: How do you clean the hydration bladder and tube?**
A: After years of backpacking, rinse it out and toss it in the freezer. Pull it out fill with water and go.

**Q: Can the bladder be taken out?**
A: Yes, the bladder can be removed. I didn't like the bladder that came with it, I couldn't get rid of the plastic taste. I replaced it with one that has two hoses.  Love the backpack.

**Q: Has anyone had any issues with adding hydration packets (Liquid IV, Gatorade, LMNT, etc..) in the bladder?**
A: None at all.  I used both Liquid I.V. and Mio.  I do rinse it as soon as I get home.  I use this to go to Disney World, and works great!!!  Good tip is after you rinse it roll the bladder and put it in the freezer.  Won't have to worry about mold growing.

**Q: Is the hydration tube freeze in cold weather?  Most hydration pack tubes freeze on the mountains for skiing & cannot drink from it anymore.**
A: It will freeze as any other product would in freezing conditions.

### ⭐⭐⭐⭐⭐ Parfait pour les randonnées d'une journée ou un peu plus
*by A***R on 20 July 2024*

Je l'ai utilisé à moto et je suis très satisfait. Léger et confortable. L'eau reste froide durant plusieurs heures. J'ai failli prendre le 3L, mais je pense que ça aurait été trop gros dans le sac. Le 2L prend déjà beaucoup de place. Pensez à ajouter un contenant isotherme si vous voulez transporter d'autres aliments. La poche de 2L prend tout le compartiment isotherme. Je n'ai pas utilisé le protège pluie, mais il est de bonne qualité et caché dans le fond du sac. La qualité du matériel est très bonne et il y a des trous pour évacuer l'eau qui pourrait couler dans le sac.
