We hear it all the time - about how our packs are expensive. The funny thing is that is comes many times from people that need a really good pack! Heavy loads mean a pack has to be exceptionally well made to withstand the stresses of heavy loads. McHale packs can take anything. All packs are not created equally! Then there's the Bypass Harness. By itself this feature makes the extra cost of a McHale Pack worth it. Don't settle for mass production when you can get this for just a bit more! Then there's the Bayonet, Super strong CM frame......the list goes on. You don't have to buy a McHale Pack, but if you don't, you do have to buy something else!

The widely spaced daisy chains accept shovel pockets and other accessories without extra hardware being sewn to the pack and the compression straps end up being shorter and lighter. This pack is big enough without the secondary extension skirt so customers usually have it made without. The official weight of our ultralight packs is calibrated with the Summit Flap on as in the photo right. It is even lighter in roll-top mode without the lid and straps. This pack is big and versatile and very effecient weightwise for what it can carry. McHale Expedition packs are among the lightest in their category.
