Klim Nac Pak Hydrapak Backpack

The Nac Pak Hydrapak Shape-Shift Bag from Klim is a medium sized backpack, perfect for those day trips that might turn into overnight stays. Versatile, the Nac Pak carries both your small or medium laptop and your tools. Additionally, the included 3L Hydrapak Shape-Shift bladder will ensure that you stay hydrated. The water bladder is completely reversible, so you don't have to worry about gunge and gunk growing in the Hydrapak. The Shape-Shift top opens wide, so it's easily filled. Then just fold over the lip and slide the clip on for a spill-proof seal. The Klim Hydrapak Shape-Shift also can be frozen, so you can get a cool sip out on the hot trails. Want something a bit warmer on those chilly days? The Shape-Shift can hold up liquids up to 140° F.

For those who dare the snow pack, the Klim Pak even has a place for an emergency shovel and probe (both sold separately).
