M4 40L Backpack

It's not very practical to have a designated pack for every activity—a skiing pack, a climbing pack, a trekking pack, and a mountaineering pack—which is why the do-it-all Camp USA M4 Backpack is a multi-sport adventurer's dream. Kitted out with A-frame ski carry, ice axe loops, trekking pole holders, a rope strap, and stow-away helmet carry, it can load up all the gear you need for a day or two of skiing, climbing, or backpacking, and it'll save room in your gear closet when you get back home. The steel wire frame stays support your load comfortably while still flexing, and the ventilated EVA back panel and shoulder straps carry well and help you stay cool. To handle both approaches and technical climbs, Camp USA designed the M4 with a padded waist belt that can be removed to lighten things up for the summit push, and it hooked the waist belt and chest strap up with EZ OP buckles that are easy to work with gloves on. The M4's also compatible with your hydration bladder, so you can keep your gullet moist. It has handy pockets on the waist belt, shoulder straps, and lid to keep your camera, GPS, phone, and snacks easily reachable when you're on the go.

This pack made the week

Familiarity:
I've used it several times

Had the pleasure of going on CAMP USA's Adventure week with some of my Expert Gearhead comrades and the guys from CAMP threw all the gear out on the table(or the hood of a vehicle). We spent the whole week camping and climbing with a focus on fast and light, spending all of our time in the high alpine. I used this pack everyday from sport climbing days to ice climbing days to traditional climbing days. The 40L is the perfect size. I love the ice axe carriers are well done and I easily able to throw a 3rd alpine axe on. Comparing the M4 to the M5 I like that the M4 has a burlier 600D ripstop polyester on the front, lid, and bottom of the pack. It does add weight but it will withstand more abuse in the high wear areas. If you are looking at this pack give me a shout. Eric Watford Expert Gearhead 801-736-6397 ewatford@backcountry.com

Perfect Alpine Pack

Familiarity:
I've put it through the wringer

I don't use the word perfect often, especially when referring to packs. However the M4 is about as close as it gets, at least for a 3 season alpine pack. I have done everything from sport climbing to ice/mountaineering days with this on and love it. It is light and minimal but carries a huge amount of gear. the straps are lightly padded, but the pack is surprisingly comfortable. There is a rear entry panel however I don't really use that feature super often. The lid area is pretty expandable making it easy to fit a large rope on top of a extremely loaded pack. Even though the pack is 40L it can easily compress down to carry a smaller load for a day of sport climbing and not be wobbly on the approach. I haven't had a chance to use it with skis, but in the theory the side compression straps should work for that. I'll update that assuming it actually snows in Utah next season. All in all this is the best light climbing/alpine pack I have used and I have tried most offerings from BD, Patagonia, Osprey etc...

Does it All Pack

Familiarity:
I've used it several times

Camp USA makes this pack in a 20L,30L and this one is the 40L. I got to try them all out and there are some slight differences between them all but, Ill stick to the M4. My favorite part of the bag has got to be the way you can store rope over the top and the easy buckle system. At first I thought the red tab was chincy and dumb. Then I tried to get the buckles undone with gloves on, what a breeze, i know its a small detail but, a really cool feature to say the least. I went away from back door entry a few years ago thought it was pointless. The way Camp does it makes some more sense. Instead of the entire pack opening up, its just a small center portion of the back that zips open. This means you can choose what to put there so you can easily access it, makes a lot of sense to me to have my water right there. Doesnt freeze cause its on my back and easy to get access too. The zipper catches a bit but, oh well. I own the Patagonia Ascenionist as well. I had to pull out the back stay to lighten it up and this one is a little heavier than the Patagonia version but, way more comfortable to wear! I imagine a bit more durable as well, fabric seems thicker but, I havent ripped my Patagucci bag yet so I cant say better or worse. Camp USA prides itself on not only having really lightweight gear but, functional gear as well. Feel free to hit me up at bporreca@backcountry.com or 801-736-6398.
