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.

Great design. Best Bag Ever.
8 months ago
The best bag. Ever. Comfort: The interior lining is soft and cozy, providing a snug fit without feeling restrictive. The hood and draft collar kept warmth in on chilly nights. Performance: Rated for lower temperatures, it kept me warm even when the mercury dipped to around 30°F. The insulation is lightweight yet effective. Packability: It compresses down to a small size, making it easy to pack and carry on hikes. Overall, the Sea to Summit sleeping bag combines comfort, warmth, and portability, making it a fantastic choice for me. Highly recommended!

Boab synthetic sleeping bag
1 month ago
[This review was collected as part of a promotion.] The boab synthetic sleeping is a great car camping or base camping bag. It's key feature is that it allows you to unzip the bag all the way flat like blanket. It's very roomy even for tall people. The zippers are also another key feature. The zippers have some chord weaved through them that helps prevent snags and ease the zipping process. Although the boab sleeping bag rolls up wide and heavy, 5 lbs, its weight is not ideal for backpacking. You could still fit it in a back pack. For the price point the boab sleeping bag is a great buy with multiple length and width options. Along with excellent ventilation.

The Perfect Summer Bag!

[This review was collected as part of a promotion.] I'm segment backpacking the Colorado Trail and needed a lighter weight bag for the warmer trips out, and this bag is perfect all the way around, literally! I'm 5'2", 115# and the short length is wonderful in terms of roominess, length, and packability. The included compression sack really gets this bag cinched down. The zipper is easy to use, it doesn't catch and it's a great option to open the foot of the bag or open it all the way into a quilt! This sleeping bag really is the best!!

[This review was collected as part of a promotion.] This is a really great all around bag. Not crazy heavy and being able to unzip the bottom for ventilation keeps you comfortable in the warmer months but also super warm when it gets chillier. This past weekend I went on a trip when it got pretty chilly and damp and I was super cozy. The material makes it great for damp and wet weather by repelling water but not making it all sticky. Love this bag.

[This review was collected as part of a promotion.] I spend most my summer in a sleeping bag in Grand Canyon. I've been looking for a bag that is synthetic, offers more leg space than a mummy bag but with a hood so I don't loose my pillow in the river when I sleep on my raft. Not too bulky so it fits nicely in my dry bag. Zips all the way open so on warmer nights I can just sleep on top of it. Perfect fit for this traveling river girl.

I bought this sleeping bag last minute after forgetting my old bag at home. Took it out to 26 degrees Fahrenheit the first night and I wasn’t cold once. I highly recommend if considering for cold weather
Yes , I recommend this product

[This review was collected as part of a promotion.] Does the job well. Make sure you aren’t going to bed in layers of clothes. Sleeping bags are designed to hold warmth from body heat. Go to bed in base layers at most.
