It just makes sense.

A successful trip is about more than just getting you to where you need to be. It means getting you and your gear there, safely and comfortably. Lowe Alpine designed the Alpine Attack 45:55 Backpack with just that in mind. It's chock full of features to make your life easier, even when you're making things as difficult as possible.

The Alpine Attack features glove-friendly buckles and straps so that you can make adjustments and transitions when the weather turns nasty, without risk of frostbite. Because there are times when you're going to need to wear a climbing harness, and packs just don't sit that comfortably over them, a stowable hip belt was added that allows the hip belt to be tucked back into the pack when you're wearing a climbing harness. The new award-winning HeadLocker axe attachment system will allow you to attach even the most new-fangled of leashless climbing tools. Never again do you need to get turned away mid-route by a steep section of ice for which you weren't able to bring the proper tools. Those tough choices are now a thing of the past. The movable strap under the lid allows you to reposition your attached rope or crampons, allowing access to the pack without having to constantly remove and reattach your vital equipment. The less time spent in transition means faster, safer climbing. Finally, because everyone knows that skiing down is more fun than walking down, Lowe Alpine added a versatile ski-carrying system that means you can easily carry your skis on the way up and shred pow on the way down.

  • Glove-friendly buckles
  • Stowable hip belt
  • Double HeadLocker axe attachments
  • Under lid rope and crampon strap
  • Ski carrying system

It's very obvious that someone who climbs ice had something to do with the design of this pack. It's the little things about this pack you notice when your fingers are freezing and the wind is robbing you of your core warmth.

The material, a ripstop grid fabric, is almost buller-proof. The hipbelt is super comfy with padding where it's needed. I love the fact I can clip biners to the gear loops and the hipbelt even has slots on both sides meant for ice clippers.

I think one of the best thought-out features is the rope strap. It strangles your rope so it doesn't fall out, but the best part is, you can roll the top all the way back so you can get into the depths of your pack without having to worry about unclipping your line!

The hipbelt even tucks away into the pack so that it doesn't get in the way of your harness. Sure, other packs have removable hipbelts, but your still occupying space inside your pack. This way, the hipbelt is out of the way & tucked nice and clean.

Both lid and hipbelt are strippable if you decide to leave them at home. The buckles protrude out, making it easier to unclip while wearing gloves or mitts. When the lid is off, the main strap connects to the rear haul loop and brings everything together nice and tight.

My only gripe, and this is just me, ... I just wish this pack had an external crampon pouch. I like them, just my preference!

The ice tool attachment is very easy to use and the Headlocker system is genius! Strapping your tools takes less than a second and the system was engineered to attach any type of skis as well. Very easy to use with thick gloves on too. Lash points make sense and there's even places to tuck away extra straps.

Highly recommended piece of alpine kit!

Unanswered Question

How does this thing work for a 20" torso and 30 inch waist? I had the older version of this pack and it had a short torso compared to the waist belt which was way too large and I had to sew it to modify it. I liked this pack a lot and it brought me to many summits. Pretty much the perfect size for 1 to 3 nights and the material is very tough. Also like that they changed the ice tool attachment as the older version had a tough time with modern tools with thick heads.

Since there isn't much info on the net about dimensions of this pack. It is 42cm or 16.5 inches from the base of the back padding to the start of the shoulder straps.


Great Pack

Lightweight, very well set up for long day multi night treks. Especially like the strap under top for quick access to layers when managing heat or cold, also great system to ratchet down ice axes, poles, and whatever else on exterior. Great quality.

What are the dimensions of this pack?

depends on how it is packed obviously but mine is about 14-16" wide on my back, 24" long and maybe 10-12" deep.
