Shopper how hydration works?
RONALD M I just pack bottles of water with me but you could put a bottle with a tube in one of the top pouches if you wanted to, it is an excellent pack I use it all the time.
ELIZABETH W There is a spot to put a hydration pack with a tube coming off of it, and a hole for the tube to stick through so it can conveniently hang over your shoulder, just like many other packs now. It has worked great for my husband, who has this pack.
