The Osprey Variant 37 Pack is a backpack that knows that sometimes you want to climb and sometimes you want to hike. This bag is into compromising: it's not going to make you choose. Use the hipbelt for support on the trail, stow the hipbelt for keeping it out of the way on the climb. Specifically designed with climbers in mind, this bag features glove-friendly buckles and a three-point system that makes for safe and secure big wall hauling. This bag doesn't give up under any conditions: an extendible spindrift collar keeps the snow out and the weatherproof and water-resistant front pocket keeps moisture away from your gear. This pack carries gear with ease, with specified loops for downhill and cross-country skis, an ice axe holster, and a compression pocket for crampons. Does anyone really like those buttered popcorn jellybeans?

Very good pack

I bought this pack for ice climbing and alpine climbing. Great design, with many alpine specific features. One feature I was really hoping would work was the crampon/shovel pocket. This is annoyingly hard to find on many packs. Osprey does it well on the Variant (the BD Deploy 3 shovel or crampons fit pretty nice). Also great are the buckles that can work with gloves/mitten on, I thought these would fall apart or come undone easily, but they've been awesome.
This pack gives a lot of bells and whistles and still remains light.

Only improvements I'd like to see are minimal:
1. The lid could be bigger inside. It's kind of a pain to get stuff into and out of it without dumping small items all over the snow. Osprey could make some more $ making interchangeable lids for this series of packs. I'd like one big enough to fit a helmet inside (like the BD Sphinx).
2. The ice axe attachment points are on the crampon pocket, so when there are crampons in the pocket, the tools poke out from the pack (yeah, nitpicky, I know). I strap the tools down tighter to the pack by use of velcro straps to the upper load compression straps.
3. The upper load compression straps could be just a bit longer to allow strapping foam pads to the side of the pack. I am able to strap on a Thermarest prolite full length pad, but a non-inflatable foam pad is just to big (unless you use a 1/2 length pad).
4. Nuclear Red. Easy to find you in a crowd, but I would have preferred a bit more subdued color (I think... the red is growing on me now though).

All in all very pleased. Definitely would recommend the pack to others.

Great 4 Season Pack

I was looking for a winter pack that I could use in the summer if the occasion came up. I tried several packs including some other Osprey packs until I happen to see this one at a store. I placed 30 pounds (10 more than I carry) in the pack and carried it around the store. The pack felt great.

I have only used on a few snowshoe hikes this year but all on hikes after a while I could hardly tell I had the pack on. Some of these hikes including going up on some steep snow covered hills.

The pack has all kinds of straps and tied down slots which makes it great for tying down snowshoes, ice axes etc. The crampon slot is also a great place to carry the snow shovel. The top bag has two pockets and is big enought to carry those items you need quick access to.

Osprey has a winner!

Love the color

Ive yet to take this out to snowy conditions. This review is based on my experience using it as a day pack. First of all, as expected from osprey the quality and craftsmanship is EXCELLENT. I have 3 osprey packs and none have disappointed me. Although I love the color, I wish they would release it with some more color selection. The red straps are a nice change from the typical grey straps on osprey. The back support is firm and melts into your back along with the hip belts (which lack pockets but I can see why with this being geared to climbers as well). Its MUCH larger than any 37L I know of. Its almost as large as my osprey kestrel 68. The straps are rather lengthy but I rather have it too long than too short.

Not a lot new to say, other reviewers covered it well, but this pack is perfect for me. Long alpine routes, touring, cragging, whatever I'm doing this is my go-to pack. Although it was holding up well after a year of hard use, I destroyed it in a fall in RMNP. The pack actually absorbed a lot of the force and probably saved me from serious injury. Osprey's warranty is amazing and they replaced it, no problem. Nothing but good things to say about the pack and Osprey's customer service.

Great Backcountry Ski Pack

Very comfortable and stable pack. The suspension is simple and easily handles 35 lbs. I use it for single day backcountry ski trips. The size is versatile - it can be used for day hikes and light weekend backpacking trips.

This pack carries skis well. A Voile snow shovel fits in the outside compression compartment; the ice tool loops can also be used to strap the shovel's D-handle. Well thought out design.

This pack climbs with you

Good materials and an excellent combination of features designed for the climber/alpinist. Best characteristic is the way it carries a load when climbing. This pack has an adjustable internal frame and load lifters that actually let you control the suspension, making it the best pack of its size that I've used on technical terrain. The arrangement of pockets and hydration sleeve ensure that it's also convenient to use.

Love this pack

Like most Osprey products, another win. I stumbled upon this pack at a local store looking for a 2000 pack. Taking it out a few times I love it. I like the crampon patch to lash to, secures poles or axes well. Lots of adjustments and fits my back really well. I run about 20lbs in it currently and its great for my early season.
BigDumps at REI on 05/05/2011

Has more room than it looks, I use it from hiking to carrying all my kit on the crag. I wouldn't climb with this pack as its a little too large for me to have on my back whilst climbing. Its really comfortable for long hikes and the weight from all your kit does not hinder you with this pack. I love it.

jay5637177 at Backcountry.com on 07/09/2012

I love this pack. i am 6'0" 180lbs and the medium fits me perfect, you can get a really good custom fit with this pack. i use it mostly for vertical adventurers. its perfect for a weekend trip to hold your clothes and gear with room left over. i would recommend this to anyone who needs a pack for the weekend adventures.

mor4644694 at Backcountry.com on 09/30/2011

Great pack

I love this pack. I've taken it on a few day hikes already and it performed perfectly. I haven't tried to take it on any over night hikes and I don't know if I will because I don't see many options to attach tents or sleeping bags to it, but I'll keep looking for a way.

Great design, but durability issues

I used this pack primarily for rock / ice climbing day trips. For this purpose, the design is absolutely brilliant. Unfortunately, I only got to use it twice. More on that in a bit.

The zippers and straps are very well thought out. Everything is nice and large so you can do pretty much anything you need to while wearing gloves. The ice tool bungees double as a stable helmet carry if you're creative (no more helmet flopping around on the approach!). The rope carry system is nice and stable. Nuclear red, while hideously ugly, means you aren't going to lose it (or can be more easily found in an avalanche). The feed through for the water hose is openable, meaning no more losing the head of your hydration system while taking the thing out. The second pocket under the brain is great for phone, wallet, keys, whatever. Suspension is nice and cushy.

In terms of storage, I can easily get a full climbing trad rack, harness, a couple pairs of shoes, 2 liter water bladder, lunch, and a rope on the top carry, and have room to spare in the main compartment.

Really, the design is pretty much as good as it gets for a top-loader for climbers.

One problem: the bottom material was falling apart on my after only 6 days of use. Not really sure why. I'm not exactly gently on my gear, but I was using it as a climbing day pack for 6 days at Red Rocks in Nevada. Didn't do anything too unusual. Got back home and noticed a 1/4 inch hole and several spots that were quickly becoming holes on the bottom.

Returned it to REI the next day for an exchange. We'll see how this one fares. . .
