Snug as a bug.
This sleeping bag really does exceed expectations, it gets warm and snuggly within seconds of getting in it.The drawstring top makes it easy to convert to a mummy sleeping bag if you get cold when out camping.The fact you can use it as a double or two singles is very convenient and saves on arguments when the grandchildren want a sleep over.Great quality, suitable for all ages, not too bulky, I would highly recommend it and will be buying more for our next family camping trip.

but I was comfortably warm. Impressed withe the price and quality
Used the bag for the first time at the week end and was well impressed. Night temp was about 8 degrees, but I was comfortably warm.Impressed withe the price and quality, no lose threads.The zip functions well inside and out with no snagging.I was on a motor bike so was impressed with the small pack size which fitted neatly into my pannier. I also tried it in my 35 litre ruck sack and it fitted snuggly in the base, so will be handy for summer wild camping.I'm 12 stone and 5'9. Had enough room to move around in my sleep and didn't feel pinned in like I have with more expensive bags.I think for colder night the addition of a thin micro fleece liner would help extend the bags lower temp range with out compromising inner room.All in all a good well made resonably priced sleeping bag.

Superb product, needs instructions for storing in bag provided.
The sleeping bag arrived very quickly, was loaded into my motorhome ready for use the same evening and off I went on what turned out to be the hottest weekend of this year! I opened the very nice protective bag, pulled out the sleeping bag and this was my biggest mistake - read on....The actual bag is lovely, lightweight, soft material very nicely lined and invites you to climb in straight away!I unzipped it, being careful not to catch the zips in the edge of the lining, snuggled inside, put my pillow in the hood, zipped up and found it a bit too restrictive across my shoulders. The bag measures 21" across and I measure 18", so very little room to manoeuvre IF you want it zipped right to the top, however, it does wrap itself warmly around you, is almost 7ft long and I had the most comfortable night ever in my van.My mistake was not taking note of how it was packed into the protective bag. I have tried all ways to fit the mummy bag back inside and failed, so the sleeping bag is now stored in a "bin bag", which doesn't do it justice and is very disappointing.Could The Body Source please include instructions on how to do the above, which I am sure would be greatly appreciated by customers, especially those camping outdoors. Apart from that annoyance, as long as you are not a very broad and over 7ft tall I can thoroughly recommend the bag!

Comfortable sleeping bag that is easy to carry
I purchased this sleeping bag to get me through 5 nights of camping at a festival abroad. It certainly delivered. The bag comes folded up in a small carrier bag and was surprisingly lightweight and small. The carrier bag has little straps to help carry the sleeping bag. Once taken out, you can tell that it is a quality product. It is well padded and the zippers are of good quality. Lying inside the sleeping bag is comfortable and I had no problem sleeping snugly inside. It was of great use during a couple of cold nights. I did not have to test the waterproof aspect to it (fortunately) so can't comment on that, but the product is of a really good material and build, I have no doubt that it wouldn't let a drop of water get anywhere near you. At this price, the product is well worth a purchase.

Very warm
Warm!....only slept in 2 ° C so far and was in light pjs and toasty. I'd reckon 0 degree nippy though with good sleeping pad. Very comfortable and easily packs away. But is heavy and bulky . But unfortunately zip has failed me as very snagy. 😕. Then completely failed and broke...Did pach work on it but awkward to use now. Good first bag but upgrading to a new one.2023 ..... Only 6 months of use from last review and upgraded my sleeping kit to a mountain warehouse 700 and thermarest pad. But still have this as spare..... I did repair Zip kinda ....but still useable. Still worth buy in my opinion ☺️

Affordable price for a warm sleeping bag of exceptional quality. Definitely recommended !
Excellent sleeping bag at an affordable price. I have used it while working at Glastonbury 2016, which was a wet, rainy and muddy festival, and I haven't been cold at night at all. I was actually pretty warm at some points, even sleeping without wearing anything else -in a tent, not a van. I did have a sleeping bag linen though, in cotton, and my tent's floor was well insulated. However this does not lessen the quality and warmth of this product. The only time I felt cold sleeping, it was because my upper body had slipped outside of the bag since I was warm at first and didn't close it well. There is a cord to close the bag at shoulders' level (or just above), and another one for the hood of the mummy shape. If you are looking for a good sleeping bag, not too heavy or bulky to carry, of good warmth and quality, look no further: you have found it. (And no, I'm not getting any commission for this review. This bag really is so great.)

Actually decent
The bags are actually pretty good, used them recently on a hike, weather got down to 10°c and was perfectly fine! However my feet did get a little bit cold but what can you expect from a really cheap bag, the hood could do to be a little bigger and zips a bit bigger but again for the price you cannot complain im just being picky! Definitely recommend for summer camping, would not recommend for any other season other than summer! 😊
