GOSSAMER GEAR Silverback 55 Backpackis a more durable version of the Gorilla which has been morphed into the most configurable and durable pack that Gossamer Gear have ever made. 

This pack is great for everything from off trail hiking that involves bushwhacking, ski touring, mountaineering or overnight camping trip. This is the first pack from Gossamer Gear that can carry upwards of 40 pounds, in order to do that they created a removable lightweight polycarbonate frame that doesn't sacrifice your comfort.

This is the most comfortable pack that you have ever carried due to weight transfer that the frame carries directly into the hip belt and with the addition of the air flow back pad.

This unique pack has three different top closure options: you have the standard removable top lid, you can completely remove it and have your roll-top dry bag. You can also unclip the dry bag style and do your compression roll top. 

Silverback is feature-rich and has no shortage of pockets and storage. This pack has a lots of great features like pockets in belt, open compartment on outside of pack for rain gear, lunch...large water bottle pockets that make it easy to grab as you're hiking along, roll top & full side compression. It can be compressed pretty small for shorter trips. 

Pack features Robic & Extreema fabric ripstop nylon to hold up on off trail use. The Silverback comes in two sizes (medium/large) with a one-size-fits-all hip belt (included). Silverback has an air mesh suspension system and comes standard with an air flow sit pad.

NOTE: If you are not using a hipbelt you should not use the stay. You need to pull it out otherwise it can cause damage of the backpack.
