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.

Perform Down Bag -7C

Overall a great sleeping bag. The toe box area has plenty of room for your feet and the bag packs down really small to fit in your backpack. The bag is soft and lightweight, plus it comes with ear plugs and an eye mask for comfort. The shoulder room wasn't the greatest, but I am 6'4" at 230 lbs, so my shoulders are a little broader than most. I would recommend you purchase this bag if you enjoy backpacking, hunting, and really anything outdoors.

AMAZING BAG for the experts
2 years ago
This bag is awesome! Since I've got it, I have already put over 45 days in it. It holds it down, the pockets and hood is well thought out. The middle zip is convenient and the zipper doesn't snap, so I never worry about the dreaded morning fluff pile. It packs nicely. This bag comes with an AWESOME compression sack, a wicked black out eye mask as well as ear plugs. The best ready, set, go camping kit for those that are heaving outdoor users.

Best sleeping system I have ever used.
2 years ago
I did a week of camping around the southern Okanagan on a rock climbing trip and slept in the bag each night. Slept like a king every night. The eye mask blacks it out and there are a set of ear deci damps. The sleeping bag is super comfortable, highly functional zippers that don't catch on the fabric. I could go on and on but this sleeping bag did not disappoint on any level.

Lightweight, Compactable, Super Warm

I haven't had a chance to take it on any excursions but have used it for car/ tent camping and have woken up sweating on multiple occasions. The down packs very well and doesn't stay bunched when unpacked. Zipper doesn't snag and the complimentary sleep mask is a nice touch for people who struggle with light sensitivity.

Very confortable and soft. It is also quiet, I move a lot so it's good for my girlfriend too. The best part is the central zip with the anti-snag, you can't go back to side zip after trying it. Overall it seem tough, I sleep 1 month in it. Con: it's not the most compressible sleepingbag

One week in the Grand Canyon from 30-50 at night and slept great. Rained last 3 days but bag outperformed and a little damp kept me warm. Great value at discounted price. Center zipper a bit getting used to but worked well. No sleeping on your side with a zipper underneath you.

Warm & Comfy

The most comfortable bag I have tried in this temperature range. The zipper is fabulous and doesn't snag, the inside is soft and I felt really warm sleeping with nothing but underwear at -1 Celsius. It packs small and the earplugs and mask are a small bonus

This bag is extremely comfortable, it condenses down to a very small size, and clearly uses high quality material. Has been nothing short of amazing on cold nights in the mountains. Love the middle zip, too.

Good quality bag. I tend to sleep with my arm under my head, so the tightness of the hood isn't ideal. Otherwise it's plenty warm, the zipper is snagless, and it packs pretty tight.
