Coldmaster™ down sleeping bag 30°F / -1°C Ultralight and Multifunctional

This is a good sleeping bag for moderate weather. I haven't been brave enough to try it in the cold because it seems too thin for really cold temps, but I like it for mild nights. It's light and packs easily. It's soft and comfy, overall I'm quite happy with this light sleeping bag.

I live in Florida and hike / camp in areas that get chilly. I selected this sleeping bag as a versatile option to use in our hot & humid weather to put on top of my air mattress and also take on hiking trips where it gets chilly at night. For really cold nights the 'hood' top of the bag can be drawn closed to keep your head warm. The bag has very durable zippers. It's designed to fully zip tight like a mummy for maximum warmth, or partially zip so your feet can hang out. The top 'hood' section can also be detached. Packed with features including stretchy straps to attach it a ruck sack or camping gear. It's soft and has a down type feel. I was impressed that I would sleep on the top of it over my air mattress without getting hot during an overnight camping trip with the temperatures were in the 80's. The sleeping bag rolls up small to fit easily on a backpack. Works well for airplane travel or for hike in primitive camping locations.

I really like this bag. I ordered it late September, very lightweight perfect for packing and to move around with you. Comfortable and cozy enough for them cold camping nights.I was a bit nervous that it had lost its loft and warmth being in the bag but when I pulled it out and shook it out it popped right up and was extremely lofty!I was actually Hot in this bag at night but it is the end of summer in my area where the temperature is can get down to mid 50s at night.I love that you can open the whole thing up like a blanket or just open the feet or zip it closed. The hood of the sleeping bag can be zipped off a well.The zippers are big and of good quality. I'm 5.9 tall/ 195lb and I had plenty of room from side to side zipped in with lots of space to move my feet around.It is a nice quality bag and I do recommend it highly ??

I like that it's more spacious than my mummy bag. And that I can let my hot feet cool off by opening the zipper at the bottom. Easy to roll around inside without accidentally moving the bag.Compresses and decompresses nicely.

used it tent camping at the end of October in the 40s. I was never cold despite how thin it was but to be fair I had brought an extra lightweight blanket. I cant say how it would perform under 40 degrees but you should be fine to at least that temp without another layer. Its light, thin and packs easy. Great for the price.
