Our UL Alpine Packs are famous for their simplicity, failsafe ruggedness, and outstanding performance level. They have been used on many Expeditions around the world over the last 30 years and have adapted well to general backpacking. McHale Packs are Custom Made entirely in Seattle Washington. Dan Mazur at SummitClimb.com gets a kick from his McHale Packs.

If you insist on minimum pack weights, McHale Packs offers these ultra-light packs. You may be able to find even lighter packs, but consider the mechanical advantage McHale Packs offer. Our packs comfortably carry more weight per cubic inch of volume and per ounce of weight. People that go out regularly year after year know that pack performance trumps pack weight. These are not fragile packs. They are made from our standard selection of tough US made and quality imported fabrics ( we tear test all of our fabrics to make sure they meet our standards ) and are built to our reliable high standards. Back in the mid 80s we called our climbing rucksac 'rocksac'. This is were the acronym SARC came from: Super Alpine Rocksac like the one pictured below and like the pack (S-Sarc) Mark Bebier climbed Mt Forakers Infinite Spur with in 1989.

Click on the images below for detail pages - Until the features page is reinstituted please understand that even though we show 'models' of packs, the way the customizing really works is everything you see is an option and can be mixed and matched, but it is far easier to start with examples like those below and add or subtract features from them. Any feature that is seen on one pack can be applied on any other pack with few exceptions. P&G Bayonet Frame Extensions - example photo click here

Critical Mass Packs; Although we sell mostly the lighter Sarc Series packs above, we sell a surprising number, in these days of 'UL', of the CM packs below. If you truly need a pack to carry loads that are 60, 70, 80, 90 lbs and above, do yourself a favor and try one of these amazing packs. They do not have that oppressive and strangling feeling like many other big internal frame packs and are more like what people wish internal frame packs AND external frame packs were like. They are a very different machine and the best big load packs on the market, as well as the lightest.

"Big load, long trail & hard climb, all eliminate by my Critical Mass Alpine II Bayonet. I just focus to climb until summit and safety down. A great success on Mt. Yari with my friends and McHale Pack. Thanks a lot, Ben" (click image for blow-up)
