A new addition to our line of Ultralight packs, the long over due 40L backpack. This is a great mid-size pack for ultralight loads, suitable for anything from a thru-hike to weekend trips with friends. This pack has 40 liters of internal volume, and about 10 liters of external volume making for a total of 50L when the pack is filled to the brim inside and out.


This pack is for those who want something just a bit bigger than the 35L pack, but who don't need all of the capacity of the 50L pack. This pack will fit the bill for anyone looking for a pack that is suitable for almost any trip long or short. 


This version of the 40l pack comes with a fully padded/sewn-in hip belt and a full frame system making it capable of carrying loads of up to 35lbs comfortably. The frame consists of two removable aluminum stays and a foam back pad. The padded hip belt is sewn-in which provides the best possible transfer of weight to the hips.


All of our packs have the same S-shaped shoulder straps which work great for both men and women. Our shoulder straps are about 2.75" wide and are made using high quality 1/2" foam, 1/8'' spacer mesh, and a 400D diamond grid ripstop Nylon material. This makes for a very comfortable 5/8" thick shoulder strap. Our shoulder straps and hip belt wings are both reinforced for extended life.


This pack is constructed out of tough 4.8oz VX07 X-Pac material for the main pack body, VX21 for the side pockets and back panel, and VX42 for the bottom of the pack.


We also have a variety of additional features to add to your pack. They can be found here: Backpack Custom Options and Accessories.


This pack is big enough to fit a large bear canister inside vertically.


Our packs are hand-made by us right here in Michigan and are constructed using the finest materials and the best construction methods. All seams are flat felled and double stiched, with select seams being triple stitched. These packs are ready to handle anything you can throw at them, and will give you thousands of miles of use.

While our packs are highly waterproof, they are not seam sealed, so the use of a pack line/waterproof stuff sacks is recommended. We recommend using a trash compactor bag, as they are cheap and very durable.


All of our packs are made to order, see our home page for current lead times.
