Description

The ideal place to spend those winter nights.

When all the three-season wieners store their camp gear for the winter, bust out the Western Mountaineering Puma Gore WS Sleeping Bag, and head into the mountains for a solo venture. From overnight ski tours to remote alpine climbs, the Puma beats back the cold thanks to weather-resistant Gore WindStopper shell and 35 ounces of light, lofty, 850-fill goose down.
  • Breathable, water-resistant, windproof WindStopper shell protects the down insulation from frost, condensation, spindrift, and howling winds
  • Ultra-premium 850-fill down insulation retains your body’s warmth and provides a higher warmth-to-weight ratio than any synthetic-fill insulation
  • V-Block side baffles keep the down insulation from shifting and developing cold spots
  • Interlocking draft tubes and a down-filled collar prevent energy-sucking drafts from zapping your slumber
  • Wider shoulder girth allows for extra layering in brutally cold environments
  • Western Mountaineering bags are made in the USA

Top Notch Quality and Performance

  • Familiarity: I've put it through the wringer

This was my first of many products from Western Mountaineering, and certainly not my last. Excellent craftsmanship due to the precise stitching and evenly distributed 850 fill down. Western Mountaineering takes exceptional pride in making their products perform and last. This bag compresses into a medium sized sea to summit compression sack and is very true to its temperature ratings. I strongly recommend you try out Western Mountaineering if you want something that will last and outperform any other.

One of the best

  • Familiarity: I've used it several times

This bag is fantastic. Great performance, warm and holds it's rating. A bit heavy and bulky, but totally worth it.

Sweet super warm well made bag

  • Familiarity: I've put it through the wringer

Toasty to -30F and wind/waterproof for stormy outings. I'm still torn between this and my older feathered friends, but the windstopper is so good that this gets more use and maybe stuffs smaller. Except for 8000m peaks or the arctic winter this is all you'll ever need. Haven't had it refilled yet but I think Western could do it and the fabric will probably last that long.

can you zip two of these bags together...

can you zip two of these bags together with a left and right zipper?

Best Answer Responded on

Yep, same zipper types. Disengage the trollies and zip back into the opposite bag's teeth.

You might end up with some warmth issues though. Spooning and romance are all fine and good, but at 25 below, that extra space might require keeping your clothes on. It's just the nature of air inside sleeping bags. Western Mountaineering not being an exception.

Responded on

Just get a wider bag. At the cost of a western mountaineering bag plus a bit most places will custom make one a bit wider

Saved my bacon

I spent 11 days in the Eastern Sierra Nevada from 8 to 11k during April. This phenomenal piece of gear was amazing. I received it as a gift for graduating med school and I love it. We had a 5 day ice/sleet/snow/rain storm and over the trip I watched as my friends bag's deflated with the inevitable moisture build up. Every day, I would pull this bag out and it would inflate like a hot air balloon. With temps hovering below 10F and significant moisture in the air this bag performed flawlessly. I was never cold (at night) and it shed tent condensation while breathing away my considerable persperation. I am blown away by the quality of the material and the precision of build. The zipper is effortless (even at 2am when my brain cant figure out inside from outside) and NEVER snagged. I have 7 sleeping bags from various reputable manufacturers and nothing compares to this quality. Nothing but positive things to say. At 3am when its frigid outside I am so grateful to have this thing.

Is this bag water resistant?

Is this bag water resistant?

Best Answer Responded on

Yes, same as the Bison WS. Gore WS is their same laminate without the PU coating... its not as WP as what they have now, but they can still use this laminate and call it water resistent. It is HIGHLY water resistent! You will love either the Puma or the Bison, depending on where you're going, Garrett. Have fun!

Hey gear experts! I'm looking for a -20...

Hey gear experts! I'm looking for a -20 to -30 bag that can be used in the Andes as well as Denali and I have heard great things about the Puma. What do folks think about the incremental benefits of the GWS vs. MF in those conditions? Is the wind/waterproof GWS worth the extra weight? The MF is 6 oz lighter which is very tempting... 3lb 4oz is super light for a -25 bag! Thanks for any feedback.

Best Answer Responded on

I think the waterproof shell is worth the extra weight. When it's cold, moisture mixed with down is not your friend. There are too many opportunities to get moisture on the bag when it's cold due to condensation in the tent, etc. I'd hate to be camped out in -20 degrees and wish I'd spent a little more money. I own the GWS, and it's really good.

Responded on

Thanks so much! I think you're right. I also called around to some of the guide companies that go up Denali and they all recommended a bag with a waterproof shell.

Responded on

Hey Mads,
Have to say I'm envious of your Andes trip. You are probably back by now. However, I bought my WM Puma in 1994. The down was probably about 650 or 700 at most but an incredible bag. I spent two nights in the Blizzard of '96, southern Shenandoah, VA at about 10-15 degrees and stayed warm enough to sleep. Caution: Watch out for any bag rated this low. Once you hit "0" its strictly a survival situation.

Tried and True

I bought this bag when it was the Super Puma and first came out in the early 90s. I spent two nights in it caught in the "blizzard of '96" Weaver Mountain Pass in Southern Shenandoah, Va. Since then, it's been my cold weather mainstay. Would I change anything? Yes...I think it's only about 700 down (not sure) but I'd like it to be 850. Other than that you can't beat it. Hint: Keep it in a very large storage bag and it will last forever.

Responded on

Hey Frank,
This comment is way late in getting to you. ALL Western bags are made using 850 minimum fill power down. Typically the down tests above 900 fill power but they guaranty that each oz. of down lofts to 850 cu. inches minimum.
Made in San Jose, CA.
Enjoy your bag!

Tom,
Our replies are slower than pony express. I wish I had seen your comment earlier. I was not aware they used down that lofty back then. Good to know and I stand corrected. Incredible bag. Thanks much.

Cozy Sleeper

I bought this a fews years back. I wanted a quality bag made in the US and stumbled on WM while living in Montana. I really like this bag. The first night I had it the temp was -8 and I was just fine. On a -30 night in Big Sky I slept outside just to test it - no tent on a porch - I was just fine. I got the short and overstuffed the footbox. I really like this bag. The only reason I don't give it 5 stars is because I have since found an even better bag, Feathered Friends. All my sleeping bags are made by them now, the materials are better the price is a bit less, the weight is better, made is Seattle, get to choose your color, and I love their work. This is a super bag and you can't go wrong, but just know there are options for US-made down bags that will keep you safe and warm in extraordinary conditions.

Responded on

I've been using Western Mountaineering bags for years and am completely satisfied. I was unaware of Feathered Friends but will definitely check them out.

I own and love this bag, but have recently lost the stuff sack (size XL). How can I get the correct WM stuff sack for this bag?

Responded on

TRR,
I would suggest contacting Western Mountaineering directly. Their website lacks a phone number or email addy, but you can write them via snail mail at:
Western Mountaineering; 1025 South 5th Street; San Jose, CA 95112
Good luck!

Helpful hint

Everything said about this bag is true. Refer to my review of the microfiber version for more info.One note to help you stuff the bag into its stuff sack. Gore Windstopper is windproof. Air does not excape the bag easily when right side out. To stuff this bag and all Windstopper bags, turn it inside out for a much easier, more mitten friendly time!

Responded on

Glad you mention that. I have the Puma GWS and it is pretty darn hard to put it in the supplied stuff sack if you don't turn it inside out!

True to it's rating

I used this bag for 16 days on Denali this summer and it's the best cold weather bag I've ever had. Not only was it really comfortable and spacious (I had a long)but was super warm, even at -20 a couple nights at high camp. The zippers worked flawlessly, no catching, and the insulated hood fit great and kept my dome real warm. and another great thing is this bag packs down in a compression stuff sack super small, so that leaves you mor eroom for gear in your pack.
