What's this? It's a little pack called Bump 32.......as in 32" of circumference. As shown, the Bump 33 is about 2,000 cuin with a 300 cuin lid. The pack can still expand easily another 500 cuin with the roll top. The standard makeup has 11" of bag above the frame. Left photo above is a 32 stripped and right photo is a 33 geared up a bit more. Bumps can be made in top/load panel/load form or with Kangaroo Pocket. Below; A Bump 32 made from 2 types Of CubenFiber fabric. This Multi-Cuben pack is made from Hybrid Cuben (Kangaroo pocket, bottom, water pockets, shoulder pouch, and front of shoulder pads) and CT5 high-Bias Cuben (main Bag and lid).

Back in the 80s McHale Packs made a pack called the Speed Bump - it was about the size and shape of a large speed bump. That was back in the days of the McHale Light Speed pack as well. McHale Packs actually made 1.5 lb twin stay packs as far back as the 80s but they were designed more as 'Summit Packs' designed to be carried on climbs after long approaches. In the 90s people started UL backpacking with them.

The Bump is about half the size of the old Speed Bump. Click Images. When packs get down into this volume range they are small enough and simple enough that it does not matter how durable or conventional the material they are made of is.....they will still be relatively light. This is one reason we have not made a big deal out of our lightest packs for quite a few years now. McHale Packs focus has always been with larger load carrying packs, and the ability for out packs to carry loads well 'trickles down' to the light packs. Back When Mark Bebier and Jim Nelson climbed the second ascent of the Infinite Spur on Mt Foraker in Alaska in 13 days with McHale Packs, Mark's 500 cordura pack weighed 4 lbs - pretty light for a 4,000+ cuin Alpine climbing pack at the time. In a mid-90s pack review in Climbing Magazine, the McHale S-Sarc was one of the lightest packs in the review from a weight per cuin standpoint. For all practical purposes Mark's pack would be light today - especially when performance level is considered. This Bump 32 pictured below is made of 500 cordura and weighs 2.5 lbs with it's webbing hipbelt and padded twin stay 7075-T6 frame. This pack's volume is about 1900 cuin to the top of the stays with more room to go - up to 2400 cuin. This pack can easily carry 20 lbs+ as is or even 35 lbs+ when you attach the padded hipbelt - total weight 3 Lbs. With lighter padded hipbelt options it can still remain under 3 lbs even with conventional fabrics. The pack pictured is just a sample and space filler for now and none of it's components have been made to be light. Make this pack out of any of our grid fabrics or Cubin fiber and it's easy to get to 2 lbs and less. Your body height and hip circumference at this point starts making a difference there!

Base price of $475.00 includes 2 water bottle pockets, padded hip belt, top pocket and conventional fabrics including dyneema X grid (green spectra grid not included).

Like all of the Sarc packs, the padded hipbelt can be removed and substituted with a light climbing belt made only of webbing threaded through the stainless steel padded belt attachment points. Those USA made stainless buckles are bomber too. A climber can even use a carabiner to fasten the front to save more weight, since pre-adjustment can be done at the sides, either at the stainless buckles or at an optional side adjustment buckle. A UL hiker can slide their favorite 1" side release onto the web but there are more options there as well that will be shown. The web-belt system very easily supports a 10-15 lb load on the hips so it's a big help when carrying heavier loads without a padded hipbelt. Options include a shorter than our standard height padded hipbelt with single buckle, or no mesh against the back, no lumbar pad...............

Other options include all standard options like a Kangaroo Pocket, lash-on pockets, top lid pocket or flap, panel/load top/load zipper..........
