Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.

Many great features, but thin back/ feet
Sunspot5 years ago
I bought this bag as an upgrade to my 21 degree bag that I've had for 4 years or so and has received heavy use & much feather loss. I am a very cold sleeper and plan to hike the PCT so was looking for something with a warmer temp rating and as lightweight as possible without breaking the bank. I'm writing this after I tried it out a few days ago. I'd estimate I slept in 30 degree temps, and used a Thermarest Z lite closed cell foam pad. There are so many great things about this sleeping bag that in fact are major upgrades from my previous bag. The zipper is wonderful, has a plastic piece that prevents it from snagging. The down draft collar is amazing. And the top pf the bag is amazingly warm and cozy. The knee area is wider than my old bag, allowing me to bend my knees a bit while sleeping, which feels luxurious compared with my other bag.
The interesting thing the first night I slept in it was that I was warm & comfy on my back, but when I rolled onto my side, my back got cold. It was uncomfortable enough that I noticed it several times throughout the night.
The next night I wore my down jacket to sleep, so my back never felt cold, but my butt again felt cold when I was sleeping on my side. I also noticed my feet were a bit chilly. Not freezing cold, but chillier than I've felt in similar conditions with my 21 degree bag. When I got home I inspected the back of this bag and compared it with my old bag, and there is definitely a thinner layer of down in the back. There are some patches where I can spread my hand and give myself a high five without feeling any down between my hands. One such patch is in the bottom of the foot area.
I definitely understand the utility of having a thinner layer of down on the bottom of the bag, but this seemed a bit extreme to me. And granted, my sleeping pad doesn't have the highest R value, so there's that too. But I am now very hesitant about using this on the PCT and once stores open up I plan to go in person so I can physically compare some bags ad potentially exchange this for another.

Warm Sleeping Bag
11 months ago
This sleeping bag will keep you toasty! I’m 5’3’, and had probably about 6-8” or so extra at the bottom of the sleeping bag. If you get too warm you can unzip from the bottom and stick your leg out. I wish the drawstring cord was a little easier to let out. When you’re all cozied up, I just found it a little difficult to undo. It feels like I need both hands to let it out all the way. There is a pocket on the inside but it is not very large, my Pixel 6a won’t fit in it so I imagine most phone wouldn’t. Other than those couple things, this sleeping bag is comfortable, easy to zip, easy to pack, and will keep you warm.

Super Comfy and Super Warm
11 months ago
When I first got this sleeping bag, I didn't love the mesh carrier. I thought it allowed the sleeping bag to be too puffy. I was pleasantly surprised to see that it came with a smaller compact carrier. The sleeping bag is super comfy and super warm. The fill and lining feel like high quality material. I'm 5'4 and the regular length is exactly perfect for my height. If you are 5'5 or taller, I would recommend the long length. There was very little wiggle room when I was all zipped up. I camp in different temperatures. Temperature wise, I was most comfortable when it was approximately 20-30 degrees. I slept with a hoodie and slept well. The night temp was approximately 40 degrees the last time that I went camping. I had to wear much thinner layers to not overheat. Higher temperatures than that resulted in me sleeping with the zipper open or on top of the sleeping bag. Overall, this is a great sleeping bag and an upgrade from my previous one.

My new all-around sleeping bag
11 months ago
I used the Mountain Hardwear Bishop Pass for the first time this past weekend for a two day camping trip. I typically sleep cold, and use a 15 degree bag through the summer. This sleeping bag is very lofty. Remains to be seen how it loses loft over time, but at the moments it’s almost comparable to my zero degree sleeping bag. I found it to be a fairly roomy mummy bag. The zipper has a plastic covering that I believe is meant to reduce zipper snagging. Probably adds a bit of weight to the bag but I had no issue with zipper snags. I haven’t pushed this bag to it’s limit- so far I’ve only used it for temperatures into the low 40’s- but I slept very toasty this weekend. I was able to compress it down easily into a smaller stuff sack than the one it came with; I'm sure it could compress even further, but that’s probably up to deciding what impact the compression might have on the loft. It still doesn’t pack down super super small, but for a women’s 15 degree bag, I’m happy with it’s packable size. On my scale, including a stuff sack, the bag weighted in at 2 lbs 10 oz, which seems pretty accurate to the bags advertised weight. If you’re an ounce counter, there may be lighter bags out there, but I’m impressed with the amount of loft that’s packed into that weight. This is my new all-around bag, holding my 0 degree only for extreme winter temps.

Warm and comfy bag!

I recently used this bag on a weekend camping trip in Northern MN. I'm 5'3 and the regular was quite roomy. I like how big the draft collar is and it compresses down nice and small. Color is beautiful!

Great for cool nights
11 months ago
This sleeping bag was quite an upgrade for me. It’s really warm and roomy while not having too much extra space. I’m 5’5” and don’t need the extra length, but I always like a bit of extra room. 15 degree gives me a lot of options to use this bag, especially for Colorado nights. There is a small pocket inside, making a headlamp easily accessible. It comes with two stuff sack, one to really condense the bag and another to allow it to expand—a nice touch.

Cozy bed

This bag feels wide enough to stretch out my legs even though it’s a mummy shape. Warm but breathable even in warmer summer temperatures. I tried it sleeping open air without a tent and it was water resistant to morning dew. Color is appealing. Appreciate the sleeping pad loops as I otherwise roll off my sleeping pad!

Kept me warm!
4 years ago
I bought this bag because I am ALWAYS freezing in sleeping bags and was looking for something that would keep me warm even into the fall and spring of Western Colorado. I tested this sleeping bag in my backyard last night and it got down to twenty and not even my toes were cold! I had on a thin long-sleeve, shorts, and thick socks and thought the bag held up very well. There is a puffy layer along the zipper and neck area to block any wind or cold vents. I could sleep on my side without cold air coming in if I cinched the face area a little bit, but it was really easy to adjust to my liking. I was very comfortable in a regular length bag and I am 5'5" with an athletic build.

Narrow hips and legs
5 years ago
I replaced by 10 year old North Face Snow Leopard sleeping bag with something lightweight. This fits the bill, but the legs and hips are very narrow compared to my old bag. I should have paid more attention to the hip girth- this bag is 8-10 inches smaller than other bags I was comparing while shopping. For reference, I'm 5'5" and 160 lbs. This is probably great for more slender or athletic builds, but for those of us with some curves, it's borderline claustrophobic and will not even allow for side sleeping.

Great sleeping bag, but not as warm as I thought
4 years ago
Don't get me wrong I really like this sleeping bag and I wanted to give it four stars, but I am a cold sleeper and this bag didn't keep me as warm as I thought it would. This is definitely a good 3-season sleeping bag. I have taken this bag in both cold and warm temperatures. The lowest I have taken this sleeping bag to sleep in was 30 degrees. I woke up multiple times from the cool weather, even in this sleeping bag with a properly rated sleeping pad and thermals. I would say the majority of the heat loss was from the sides of the sleeping bag. However, I still really enjoy using this bag, but since I am such a cold sleeper I tend to use this bag for more moderate temperatures. If you are a cold sleeper I would recommend using a warm sleeping bag liner in combanation with this sleeping bag.

Durable, lightweight, snug bag
3 years ago
My only complaint w/ this bag is that my bum gets cold (back sleeper, 5'4, 130 lbs). That could be though because I only use a z-lite sleeping pad. It's been with me on: 4 days on the JMT in summer, up Mt. Shasta in May, various camping w/ kids trips, and each time it's just warm enough, but not necessarily the warmest. That said it's very versatile: backpacking, mountaineering, camping. I pack it w/ a compression sack and it fits on the bottom of my backpack perfectly. Just know if you run cold or like to be super warm at night, one might think about purchasing a liner. Otherwise the warmth and lightness are definitely worth the price, it's very durable, easy to use. I like the mummy fit. Just a hands down well-made bag.
