The Warthog 45L has an excellent weight-to-performance ratio. Its modular volume and removable accessories make it a very versatile mountaineering bag.

An extremely comfortable and lightweight backpack: its innovative AlpinePro suspension system features an S-shaped removable back panel that perfectly optimizes the load on your shoulders.

The Warthog's compact 45L volume lets you carry everything you need for a multi-day excursion: ropes, crampons, ice axes, helmet, down jacket, bivouac gear, etc.

High-tenacity nylon fabric material makes this bag ever more robust for intensive use.

Best Bag I've ever used

I have spent 300+ nights in the backcountry as a guide. Naturally, I've used a lot of different packs. The Warthog is, by far, the best. It's lightweight and it's space efficiency is remarkable. Everyone in my group had 70L bags that were overflowing. I was able to pack the same amount of stuff (including climbing gear and a rope) into/onto my 45L bag with ease. It feels much more comfortable than an Osprey (with a much better price) and has the durability of a black diamond bag (again, with a much, much better price)

everyday use for 3 years

I bought my warthog about 3 years ago at the start of summer 2019. I've taken it up several mountains in western Canada, to all the crags I've been to since (except maybe a handful of trips where my partner carried all the gear), on a lot of splitboard tours around the Monashees, Selkirks, Rockies and Coast mountains (so many powder turns!!), to big bush parties and on most of my grocery store trips. It's a great bag, it was a bit uncomfortable when I loaded it to the brink up to applebee dome in the bugaboos, but I just brought too much stuff. It's also holding up very well, many other bags would've teared the way I treated it on rock and snow. The only thing that broke is the draw cord around the top, and I don't really need it, if I did I'd just make a new one with some cordelette that could double as tat in a pitch.

I expect this bag to last for a long time and I'm going to be sad the day I have to retire it.

Light weight and comfortable

This pack is well designed, lightweight and handles a full load well.

Good, with caveats for my build

To be honest, I put this pack to the test straight away, 28 mile hike in with about 35-40 lbs, 3k vertical feet of ice with it and 28 miles back out. On the way in, at about mile 10 or so my shoulders hurt so bad I had to give one of our twin ropes to my partner, I had tightened up the hip belt so much that my hips were killing me during our ascent at hanging belays. The hip pads for my build, 6'3" 185, weren't long enough to get them tight above my hip bones without being into the actual strap material. There's a lot of things I like about the pack, it climbs fairly well other than the hip belt being in the way with a harness on with ice clippers, probably more my build but I'm not sure. I love the minimalist part of it and I can pack my ice and overnight kit in it just fine. I kind of wish it had some shock cord on the outside for crampons but honestly this is something you can do yourself if so inclined. I have been told there is a revised Warthog in the works and I look forward to seeing that. If the shoulder straps are wider and the hip pads longer, I will definitely get the updated version.

Perfect pack for long alpine rock ridges

Finished up a week of easy (up to 5.7) alpine rock ridge climbing in the Sierra and found the Warthog to be just about perfect for carrying enough gear to bivy on route. The gear loops on the waist belt were handy and the taper of the pack body allowed for great movement. When fully packed the exterior pocket on the backside was limited to very thin items but that's a small gripe for an otherwise excellent pack. I used the Kume ski touring all winter and this was just as good for the intended application. Stoked to have discovered Blue Ice (their harness line is great too!) and look forward to getting lots of use out of this pack.
