## Questions & Answers

**Q: What country is it made in?**
A: Philippines. Not USA.

**Q: Is it possible to take out the water bladder and just use the backpack?**
A: Yes.  The bladder is removable and you could then use it as a small backpack.

**Q: My hose keeps getting a kink in it when I drink.  How do I avoid this?**
A: are you saying that the tube itself has a crease in it like it was folded and then pinched?  Can you tell if the hose is damaged in some way (funny colors or marks)?  If so I would guess that it needs replaced and that would probably require a conversation with the company directly.  Otherwise you would have to insert a second tube into where the damage is to reinforce it, and I would assume that it would start to degrade and start to leak at that point.  Good luck

**Q: will the crux 100oz short fit this pack?**
A: I'm not 100% sure on that, the short looks pretty Wide in comparison with the 100oz Crux that's inside the bag.
