KeenFlex Envelope Sleeping Bag 3 Season Extra Warm Waterproof Advanced Heat Control System – Ideal for Camping Backpacking Hiking Festivals Twin System

This envelope sleeping bag gives you more leg room than a mummy sleeping bag ideal for a better nights sleep. Zip on each side makes it easier to get in and out and let's you open the bag symmetrically when you get too warm. Neck baffle keeps the cold out when the temperature drops. This is not a true backpackers sleeping bag as it is not small or light enough when every kilogram of cubic centimetre counts but nevertheless it is good value for money for a camping holiday bag. Needs to be washed in an industrial washing machine or dry cleaned which I didn't find out before buying but that's not a major problem. I would certainly recommend this bearing in mind what I have said above.

First class sleeping bag for that price. Lightweight and very warm. Zipping and unzipping from inside the bag is unusually easy. Not easy to roll back tight enough to get back in the bag but it is possible and it is then very compact. It would be perfect if it it had 2 bags, one if you want to work hard at making it very small and one if you don't care and just want to pack it.

I really like the soft, cosy lining; also the good strong zips on each side, and the drawstring hooded bit which held my pillow in place.But I tried it in a tent in my back garden in May and I needed a duvet on top- and a woolly jumper, pyjamas, socks and leg-warmers. It was quite a cold night - 5 degrees Celsius. Probably ideal for visiting friends who are short of spare beds but have heated homes

I bought this for my elderly father who has arthritis and feels the cold a lot. He is thrilled with this sleeping bag because it is super light, so it is easy for him to lift with arthritic hands. It is also very warm. A very good buy and excellent quality.

Having zips on both sides is a godsend her bag hasn't so depending on where we crash sometimes I'm on the left and sometimes on the right. Now it's no hassle and I'm toastie warm too. The stuff sack is generous too and the bag goes in comfortably and scrunches down too.

Very effective. So comfortable that we (me and my kids) just use one each as our normal bedding in the house. Look very nice too. And are very sturdy. Kept us warm throughout the cold winter, so very effective.

I was persuaded to buy this bag because of the double zip feature - it seemed like a really good idea to make getting in and out less trouble. In practice, though; it doesn't really work; it's really difficult to get both zips pulled up to the top once you are in it and unless they are fully closed with the top tab fixed in place, they tend to open up again during the night. In the end, I'm just leaving one of them permanently closed up, so it has effectively become a one-zip bag! Nice idea but needs more thought. Other than that, though, a good quality bag of middling warmth/thickness.

Bought this for my daughters sleep over. She loves it and likes to sleep in it at home as well. Good value for money, warm and comfy!
