Granite Gear Perimeter Backpack

The Perimeter is designed for high adjustability. You can fine-tune both the torso length and the shoulder width to match your specific frame, while the RE-FIT hip belt allows you to adjust the waist sizing to ensure the weight sits comfortably on your hips.

The pack is rated for a load capacity of up to 40 pounds. The internal frame, which uses a spring steel rod outline and a PE board, is engineered to distribute that weight effectively across your back and hips.

The cinch-and-roll closure functions like a dry bag, allowing you to compress the top of the pack down to secure your gear tightly. It is generally more weather-resistant and flexible than a standard zipper, as it lets you adjust the volume of the pack based on how much you are carrying.

With a 35-liter capacity and seven external pockets, it is well-suited for shorter multi-day excursions or ultralight trips. It also includes a bottom flap specifically designed for strapping on a sleeping pad, which helps save internal space.

Yes, the lid flap is removable. This is a great feature if you are looking to shed a few ounces or if you prefer a more streamlined profile for your hike.

The Perimeter is designed to fit torso lengths between 18 and 21 inches. Because the suspension system is adjustable, you have some flexibility within that range to dial in the exact fit for your back.
