Operating as usual


When you're 100km deep into the JMT and all you want is a big warm dinner again... 🤤

What's your favorite post-backpacking meal when you get off the trail? 🍔🥪🍕


We're seeing GREEN 💚🐛🌿🌳

We're loving this natural color-inspired gear layout! Who says you can't do color coordination & ultralight packing at the same time? Our 850+ goose down keeps our sleeping bags and jackets extremely lightweight and packable, while still providing you with immense warmth & breathability for your outdoor adventures.

WM gear pictured:
• VersaLite 10ºF/-12ºC (2lbs / 905g)
• Flash Vest (5oz / 140g)
• Flash XR Jacket (11oz / 312g)


When you go out into sub-freezing temperatures but you sleep so warm you forget to wake up ⏰

Our 5ºF/-15ºC Antelope MF is designed to retain its loft in any temperature or weather, so that you wake up refreshed & ready (yes, even in the snow) ❄️

Not all packing lists are the same! Today’s comes from , who uses this list to pack for his travels worldwide 🌎

While a tent/tarp may not be necessary in these scenarios, you never know where you’ll sleep - we recommend bringing a lightweight, packable sleeping bag or sleeping bag liner to make sure you’re covered & comfortable wherever you find yourself.

Do you travel with your outdoor gear?


We can talk all day about why our down gear makes the best trail companions - but at the end of the day, the fresh air and breathtaking Mountain View’s are what it’s really all about 🌄


Double the gear layout = double the adventure 🏔

Today's gear layout comes from before their John Muir Trail (JMT) trip from Mt. Whitney to Yosemite valley. For anyone looking to get into thru-hiking, the JMT is a shorter thru-hike that features incredible views and even overlaps heavily with some of the the PCT.

Welcome to our next installment of 🔦Gear Spotlight 🔦

Today’s Spotlight
⭐️ Puma GWS ⭐️

While the Puma might not be our best-selling sleeping bag (apparently some people don’t like going outdoors in polar-level temperatures? ❄️), it’s one of the most durable and bold pieces of gear we’ve constructed in our 50-year history.

Made for only the most daring of deep-winter expeditions, this Arctic titan of a sleeping bag can handle almost any condition you can face. The Gore®️ outer shell easily repels extreme cold, icy wind and heavy snow while the nylon taffeta interior maximizes internal temperature and breathability.

Dual interlocking draft tubes provide extra insulation throughout the length of the bag, and its V-block baffle construction is our most targeted down control system. With all these incredibly features, we still manage to stick to our ultralight ethos by keeping this sleeping bag under 4 pounds total.

With its ability to perform in such harsh conditions, the Puma is perfect for both deep winter hunting and summiting Denali, Aconcagua and a host of other peaks 🏔️. We believe no mountaineer’s gear closet is complete without it, and we’re extremely proud, as always, to handmake it in the USA.

For more information on the Puma GWS, click the link in our bio to read ‘s 2019 review of this once-in-a-generation piece of gear.

Have you washed your sleeping bag recently?! 🧼
We build our gear to last a lifetime, but sometimes after heavy use, down’s performance gets compromised from taking on moisture, body oils, or dirt.

To help our gear keep you toasty 🔥🔥 throughout its lifetime, we recommend washing & treating your gear regularly. Find out how our good friend treated his MegaLite after accidentally spilling soda on it by clicking on his profile.

Earlier this December, a multi-team effort resulted in the rescue of a fallen climber on Mt. Hood. While descending from the summit, the climber fell several hundred feet, sustaining serious injuries. Luckily, a team from was on the mountain and sprang into action to stabilize her, while other workers from volunteer SAR group Hood River Crag Rats hauled up necessary gear to evacuate her down the mountain.

One of the rescue workers even provided their personal WM sleeping bag to stabilize & insulate the climber during the seven-hour rescue effort, which unfortunately damaged the sleeping bag in the process. After creating a rope & stretcher system, the rescuers were eventually able to evacuate the injured hiker to the base, where she was treated & released from a hospital.

We love seeing when people use our gear for good, and want to share this story as a reminder of the heroic first responders that keep us safe outdoors every day. Western Mountaineering would like to thank the selfless rescue workers that provided expert care & assistance in this rescue.

🔎 The third installment of our monthly Product Spotlight is here 🔎

Today’s Spotlight:
⭐️ Kodiak MF ⭐️

The Kodiak is the most popular sleeping bag in our Microfiber series and a multiple award-winning bag. Crafted with increased durability and water resistance in mind, this technical winter bag goes down to 0° Fahrenheit, making it ideal for hunting, winter camping, and backcountry snowshoeing.

The design is where this sleeping bag excels, striking the perfect balance between a more roomy interior and lightweight packability - making it great for side sleepers & people with broader builds.

Over the years, the Kodiak has garnered lots of praise, including the coveted OutsoorGearLab‘s Editor’s Choice award for Best Winter Sleeping Bag of 2023 🥇
