Great Bag That Keeps You Warm

Our family needs sleeping bags that are built to last and this one seems to match this need. My partner feels the cold and this bag keeps her happy and pro ides a good night of warm sleep. Zipper seems solid and the storage bag is well made too

Good for 15 degree temps while wearing a light layer. Can’t speak to durability and zipper performance over time.

High Quality..great Value

My girls have really enjoyed this bag. I would definitely recommend it if you're looking for an affordable bag with quality written all over it.

Good Stuff

My partner wanted a double bag, but I got this to zip up with my anthracite. Its a little bulkier than the male version, but in sure there's science behind that. I usually carry this one in my bag. Im jealous that they get the better colour.

Warm And Great For Shorter People

This was the perfect size for me (5'2“). Have only used car camping at around 40 degrees so far but was very comfortably warm. I also love the purple color

Keeps Me Warm All Night.

This was a much needed upgrade. I find myself camping in high elevation all the time, mainly in the summer and needed something that would keep me warm enough but not too warm. Temperature in this bag is perfect. Keeps me warm but still with enough room to move a bit. I have never been a fan of the tight mummy bags but this provides just enough space for comfort. Definitely would recommend this for car camping, backpacking, or tent camping.

Great Beginner Backpacking Bag

Bought for my wife for a 4 day backpacking trip in the White River NF. Lightweight and packs down small enough to fit in her bag!

Womens Anthracite 20f

I bought both the men's and women's Big Agnes Anthracite 20°F sleeping bags, and they've been excellent for three-season camping. The lining is soft and comfortable, not slick like some synthetic bags, and the FireLine Pro Eco insulation keeps warmth even around freezing temps. I've found the men's bag comfortable into the high 20s, and the women's version with extra insulation in the hood and footbox works great for anyone who runs cold. The design details really stand out: the draft collar, cinchable hood, and smooth zippers make the bag feel more premium than its price tag suggests. You can also zip them together for a roomy double setup, which pairs perfectly with a double pad. They are a bit bulky and heavier than ultralight down options, but that's expected with synthetic bags. Overall, the Anthracite 20°F is a warm, durable, and budget-friendly choice for reliable comfort outdoors.

Warm And Beautifully Designed.

So warm and comfy. However, this bag is pretty narrow. It is very beautifully designed with a great hood and zipper that won't snag. And I love the color!

Tight

I know it's a mummy style sleeping bag; however, there is almost no room for movement at the feet.

Great Value And Instant Favorite - Big Agnes Women's Anthracite 20

I bought the Big Agnes Women's Anthracite 20 for my wife as a budget-friendly alternative to my ultralight Sea to Summit mummy bag-which she would always steal on overnight trips. She loves the feel and snug comfort of a mummy-style bag, and mine kept mysteriously ending up in her pack. This bag turned out to be a perfect solution. She instantly fell in love with the color, the soft fabric, and the overall quality. For the price, the materials and build are seriously impressive. While she's not into backcountry camping, this is now her go-to for any trip where we're not in a proper bed. She's already told me she's never leaving home without it again. Big Agnes really delivered on value and comfort here.

Very Warm

I love this sleeping bag. It's very warm and the snug fit is great. I can't wait to use it for our winter camping trips - it's held up well this fall. The only thing I don't love is the color - the purple it a little more grey than it appears on screen.

Good Purchase

Awesome value, I'm 5'11/135 lbs and could almost use a tall length but works fine and comfy. Soft, thick insulation provides cushion.

Warm And Stylish!

Haven't used the bag yet, but upon unboxing it I tried it out home. Super comfy and warm, I like that there is a tall feature for us! I'm 5' 8' and chose to go for the long version rather than switch to a men's sleeping bag. I'm very happy that it has enough room height and width-wise for myself and a blanket if needed. This will be my go-to for camping and rafting!
