With our years of experience, we are pretty sure this is the pack you want to bring with you on a thru hike. 

Every pack is handmade of very lightweight material which still durable enough to get you all the way there. 

It's fully modular, with optional/removable padded HDPE frame-sheet, optional/removable padded hip-belt* and designed to work as seamlessly as possible with your kit.

You can slide a Thrupack Summit Bum onto the hip-belt* or hook it onto the shoulder straps!

At Thrupack, the primary intention of every design is function, but we like to bring style in where we can. So, there are lots of great patterns and colors to choose from to make your pack that much more personal!
