    Top-shelf materials + world class design = one heckuva bag.

    For 30 years, Western Mountaineering has been dedicated to constructing some of the finest and lightest sleeping bags on the market, and the HighLite Sleeping Bag is no exception. Unlike some other bags that claim to keep you warm at certain temperatures but fail to deliver, Western Mountaineering rates their bags conservatively and only builds them with the finest materials available. Designed to keep you warm at 35ºF and weighing in at a ridiculously light one pound, the HighLite is an excellent choice for summer outings and ultralight shoulder-season forays into the wild.

    • Ultra-premium, 850-fill down insulation to retain your body’s warmth and maintain a super-high warmth-to-weight ratio
    • Ultra breathable, packable, high-thread-count ExtremeLite shell fabric encases the insulation without adding unnecessary weight
    • Water-resistant coating protects the down insulation from frost, condensation, and spin drift
    • Horizontal seams are sewn-through, and vertical seams are baffled with 1.5-inch netting to allow unimpeded loft and prevent energy-sucking drafts
    • Slightly narrower shoulder and waist girth help eliminate pockets of dead air for improved warmth retention
    • Half-length, #4.5 YKK coil zipper stands up to years of use
    • Western Mountaineering bags are made in the USA
    • Item #WES0032

    Amazing weight saver

    • Familiarity: I've put it through the wringer

    I honestly don't know if you can beat this bag in terms of warmth for weight. I bought this to take on the John Muir Trail in August 2019 (high snow year) and was seriously impressed with it! The bag comes with a stuff sack (not a compression sack) and the storage sack. The packdown size is incredibly small and I was able to fit my sleeping bag, Big Agnes AXL pad and my Nemo Fillo into the bottom portion of my pack that was normally be completely taken over by my previous sleeping bags.

    To cut down on weight the bag has no draft tubes or any other frills, but I did not have a night where I felt cold on trail. I don't know exact temps but we slept above 10,000 ft every night and the nights were cold enough for frost to form. I would definitely recommend this for any summer backpacking adventures or some warmer shoulder season adventures.

    As mentioned in the description this bag is cut on the narrow side. If you're broad in the chest/shoulders check out the Caribou!

    Absolutely love this!

    • Familiarity: I've put it through the wringer

    I'm 5'2 and got the short version. I absolutely love this bag! I've used it way more than I ever thought I would given the temp rating. I use it with the WM silk liner. I've taken it (unintentionally) down to 25 with midweight base layers and been toasty warm. Its soft, cozy, comfortable, not restricting and warm. Best of all, it's super light and packs down tiny. (for the short, a 5L compression sack does the job). There's truly no other bag I want to take with me on backpacking trips. Used it from about April through September last year. Seriously. Love.

    An excellent bag for the weight saver

    • Familiarity: I've put it through the wringer

    I really enjoy this sleeping bag. It is incredibly lightweight and smashes down into the size of a loaf of bread. Super nice for when you are trying to keep your pack weight down. I'd say the temp rating is pretty accurate. I always hike with a light puffy coat, and usually sleep with that on in the high country which adds a bit of warmth. Prepare to layer up if the temps drop below 30.

    Minimalist Perfection

    • Familiarity: I've put it through the wringer

    If you're looking for a summer bag that compresses down to the size of your nalgene, this is it. My go to bag for spring and fall desert adventures and summer mountain backpacking! They've kept this bag under a pound thanks to cutting away all the bells and whistles. Minimal hood, no draft collars and b.s., and only a 2/3 it's not for the faint of heart, but for savvy campers and people who are looking for their go to ultra-light bag. Only in the desert can I sleep in this thing in my skivvies, but in the mountains I recommend coming prepared with thin long johns and a long sleeve shirt - preferably with a hood. Beanie is nice too. When it dips below 40 degrees, this bag will hang on but it's user also has to be dressed appropiately. Otherwise for your standard mountain evenings, this beauty is a piece of art.

    So for those who aren't shy of minimalist and aren't looking for fancy over produced bags, this is your baby.

    Minimalist Perfection

    Ultralight, Ultra Comfort.

    • Familiarity: I've used it several times

    Love this bag. I've gone through quite a few sleeping bags over the years, until I finally decided to purchase a Western Mountaineering bag. The Highlite met my needs of an ultralight bag and it also provides the room and comfort, so that I can get a great nights sleep deep in the backcountry. I'm 6'-1", athletic build with big shoulders, I feel great in this bag. The warmth is spot on for me... I typically run hotter than most, if temps drop, coupled with a base layer or down garments, you can really stretch that 35 degree rating. This bag fits my needs more than any other bag on the market and it's ultralight! Couldn't be happier and the love the fact that I am supporting a local company from my home state of California.

    Ultralight, Ultra Comfort.

    HighLite Sleeping Bag

    • Familiarity: I've put it through the wringer

    So nice! Western Mountaineering's down and construction are truly all that.

    It is a perfect summer season bag. The 1/2 zip is just enough to keep things cool when needed, while really keeping the bulk down--I have this paired with an 8L compression sack, which stuffs down to tiny. Again, so nice.

    AT worthy!

    • Familiarity: I've put it through the wringer

    Used this bag on my AT thru hike last year. switched to a 55 degree bag when it was warmer but this one kept me warm in the smokies and up north. so very light! I continue to use this in my camper - very well made sleeping bag

    temperature range

    • Familiarity: I've used it several times

    I've used the bag for two weeks in July 2014, in Colorado at elevations ranging from 6000-11000 ft. For high altitude camping, I think I should have purchased the other Western Mountaineering bags rated at 5,20, or 25 degrees.

    At higher elevations in Colorado, overnight temperatures usually drop into the 30s and 40s (even in July). If the temperature reached the upper 30s, I was definitely cold sleeping in this bag.

    The sweet spot for being comfortable in this bag for me was about 45-55 degrees. This is my first down sleeping bag, maybe all down sleeping bags are like this. Otherwise, the bag is constructed well, very light, easily pack able. I am happy with it but I will need to invest in an additional bag that is more suitable for high alpine camping

    p.s. I was sleeping in a t-shirt and boxers

    Jonathan--you should try your bag again at 35 degrees but wearing your winter clothes--I bet you'd be warm, as long as you use a serious pad (one that costs at least one hundred dollars). A t-shirt and boxers is an extreme test that very few bags can pass!

    My 2 cents

    • Familiarity: I've used it several times

    After 8 nights in a row with temps at or below the rating. For me the rating is spot on. I got too cool to be sleeping well at 36F. Needed to put on thick base layer like UA3.0 or SmartWool so I give WM a 5 on rating. I can't say I love the bag cut. The hood is cut too shallow and it needs a draft collar. Also, the zipper doesn't lock and I found it unzipping every night by 6 or more inches yet the velcro tab stayed closed. My only complaint is the cut around the head doesn't work for me. My Marmot is a dream but it's cut so deep you can wear it like a hat. If it's in the mid 40's and you like to have your head out of the bag it's great but if you 'hole up' when it's cold expect to work at getting things to line up. I have a Feathered Friends and other quality bags so it's a fair compare.

    This is a minimalist bag, it cut a whole pound compared to its 30 degree rival due to no bells and whistles like draft collars, big hoods, burlier zippers...something I really love because usually don't need all that. But for high alpine you're definitely risking beind cold. I rarely ever sleep in this bag unless I'm wearing long johns and thermal top. Only time I can sleep in minimal clothing is down in the desert! So if you're taking this bag up high, be prepared with hat, high neck shirt, and warm bottoms. Otherwise don't expect it to keep you totally cozy unless it's quite warm out!


      I purchased this pack for my ultra light set-up & I couldn't be any happier! It is made with unbeatable attention to detail & the weight of this thing is almost zero. It fits perfectly into an 8L Outdoor Research Ultra-Light Compression Sack & compresses to 6"x6"! (the OR compression sack does add an extra ounce though) Overall I couldn't be any happier with this bag!

      Amazing Sleeping Bag!

      • Familiarity: I've put it through the wringer

      I can't say enough good things about either of my WM bags. I've slept in this bag down to about 30 degrees and the weight can't be beat. Packs down very small. Great product.

      Samuel, the 6' bag packs into the 6" x 12" included stuff sack. It does fit perfectly into an Outdoor Research Ultra Light Compression Sack 8L & compresses to nearly 6" x 6"! My 6' bag weighs in at 1 Ib. 1oz. with the included stuff sack. Hope this helps!

      November7-9.My house up Rancheria to the Baskets. Camped there. Up to the top of the greenhorns and down Just Outstanding trail to Isabella for recsupply/ burgers/ beer. Rode to Keyesville and started Kern Canyon Trail, camped out by the by the River. Rode the Kern Canyon trail back to Badger gap trail to Rancheria and back home. Would be 104 miles, epic brake failure on the Kern Canyon Trail....

      Ultralight, Compact, sleep system

      • Familiarity: I've used it several times

      I have used it on three backpacking trips this summer in the North Cascades of Washington State at elevations between 6-8k'. I think for the mountains it should be thought of as part of a sleep layering system, using your other base layers as needed to increase insulation and warmth. It will save weight and space and my 4 season tent maintains a temp 10-15 degrees above the outside temp so it's range can be extended. I have used Western Mountaineering bags over the last 20 years and have come to trust there quality and temp. ratings. I have an old Alpenlite, Kodiak SDL, and a newer Bison and Puma for shoulder seasons.

      Quite Impressed

        At first glance this bag is super light and meets my needs for warmth. I sleep on the hotter side so this bag keeps me comfortable even in the upper 20's anything lower and all I would need is an extra layer and I'm fine. The fact that this bag is made in America made this bag a must buy for me. It compresses down to a little bit wider and about 2 inches taller than a nalgene bottle which saves a TON of space in my pack which allows for more food and other assorted necessities. I would recommend this or the summerlite to anyone looking for a high quality sleeping bag.

        Lightweight and compact

          The shorter zip doesn't worry me but the zipper disengages pretty easily and is a little annoying to engage it again when you're in the dark or half asleep. It may be to prevent ripping the bag. I tend to run cold so for me I need to wear a few layers to be warm at the temp rating listed. I mainly bought this bag for it lightness and compactness - it certainly does pack down small.

          Best value in ZZZ-Bag bar none...

            Western Mountaineering get it 100% right and we enjoy their toasty warmth 12 months out of the year.
            Beautifuly made right here in the good ole' USA & light as a feather , it will warm ya up when your cold and cool ya off when its hot..... It's damn near perfect.

            everything I expected from Western Mountaineering

              I just ordered and received this bag after looking at a number of sleeping bag options, including bags from Marmot and mont-bell (I currently own and love a mont-bell UL SS Down Hugger #3). While it has not yet passed the test of keeping my ass warm in the mountains, the HighLite looks like a keeper.

              My initial assessment of the quality and the fit and finish is that it is outstanding, and is everything I expected from Western Mountaineering. The fit is roomy enough (which was one of my concerns with ordering this bag), and it feels instantly warm. I really like the baffling and the down distribution. The bag is exremely light at 16 ounces, which is quite important to me. The fabric has a nice feel, and should be durable enough given its lightweight composition.

              The half-zipper provides plenty of room for easy entry and exit, and since I sleep in a bivy sack, it's not an issue for me to need to slide in from the top. Additionally, the bivy sack use means that I would not need to unzip it for quilt use, but will just control temperatures with the half-zipper and my clothing choices. The half-zipper is well worth the weight savings for me.

              The bag included a lightweight stuff sack that looked to be about 6-8 liters, as well as a very handsome and sizeable storage sack, probably the best one I have ever received with a sleeping bag. Nice touch by WM.

              I will be rolling with bag this on my next backpacking outing, and if the warmth is what I expect (and why wouldn't it be, after all, it's a WM bag), I think this bag will be my go-to choice on many of my trips. I will update this review after it has been field tested...

              Edit/Update: I returned this bag after only one use, because depite my initial assessment that it was roomy enough, it was just too slim a cut for me once out in the field with it. That might just be that I have gotten used to my mont-bell bag, but nonetheless...

              That is no reflection of the quality of the bag, but it just wasn't going to work for me.

              A couple other observations: The zipper was fussy, which as we all know sucks in the middle of the night. The fabric was not as comfortable against my skin as the mont-bell fabric. Just my take...

              You will not be disappointed...WM makes the best bags...I have a Hilite and a Badger and am going to purchase this bag because it is so darn lite...for those of you out there looking for a 30-40 degree bag, make sure you buy a mummy. I made the mistake of buying a non-mummy and have paid the price. I look forward to your update but I am confident you will love this bag.

              Whoo-Hoo what a bag...!!!

                I've had my Western Mountaineering bag for three years. It is just as warm now as it was the first time I used it. It has had a rough life, two thru-hikes on the Appalachian trail and survived the Colorado trail. It has spent half of it's life smashed in the bottom on a backpack, but it still retains all of its loft..!!The only down side is the half zipper. I understand it is necessray for the crazy light weight of this bag, but on warmer nights it stops you from opening up the bag and using it as a quilt.Over all a top of the line bag. I would not hesitate to buy another, if this one ever wears out...!!!!

                Unanswered Question

                Hello Are your sleeping bags coated with Fire Retardants or any other chemicals? Also is the down filling real down or synthetic? Thank you!

                Has anyone used this bag as a liner in another bag? We have some later season camping lined up that I don't think my 30° bag will handle and I am looking at options.

                If I am 6 ft should I order a regular or a long?

                Hi Preston,

                You should be able to fit comfortably in the regular length however it may be just a bit tight if you use a large pillow. If the slight additional weight and cost of the bag is acceptable then I would go with the larger size to give yourself a bit more room - but if not then the regular will serve you well.

                I love the specs of this bag, but I wish...

                I love the specs of this bag, but I wish it had a full zipper. Anyone recommend a bag like this with a full zip? (I understand this would add weight). Thanks!

                This product is described as "manufacturer...

                This product is described as "manufacturer defect" and warranty also says "defects". What is wrong with this item?

                I believe that is a typo. Whoever set up this page mis-wrote the specs area...

                The recommended use should be for Ultralight packing (not ultralight manufacturer defect).

                The Manufacturer Warranty is lifetime for manufacturer defect--that will cover any issue you have with the product that is due to manufacturing error (zipper stops working; velcro coming off the bag, etc...) which isn't due to use.

                So there is no manufacturer defect with this bag. Sorry about the confusion!
