## Description

Active Era - Warm M300 Sleeping Bag: This premium quality, 3-4 season sleeping bag from Active Era is made from a durable 190T polyester outer shell, with an ultra-warm 300GSM double filling for use in temperatures from 0°C to 10°C and extreme temperatures down to minus 10 degrees Celcius.

Instead of a single 300GSM filling, this professional sleeping bag is packed with a double layer containing 2 x 150g/m² hollow fibre layers, and a drawstring hood. This provides a considerable increase in insulation and warmth compared to a regular single layered 300GSM sleeping bag, and ideal for use outside in both winter and summer. Features 300GSM (2 x 150g/m²) ultra-warm filling. 190T Polyester durable outer shell - Water resistant against damp. Fully Machine Washable. Double zipper system with windproof draft tube lining for extra insulation. Secure internal pouch for valuables (mobile phones, electronics, accessories). Additional internal drawstring collar pulls above the shoulders to keep out unwanted drafts and wind. · Dimensions Length: 220cm, Width at Top: 80cm, Width at Feet: 55cm.

Review: 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.
Review: Highly recommended! - I am very pleased with the purchase of this Double Sleeping Bag; I can confirm that it is Queen Size, giving just that little bit extra room for two. The inner material is very comfortable and doesn't slide around like many others do. Have only used it for two nights in our VW T4 so far, but the wife and I were very impressed with the quality. I agree with another purchasers comment that you have to be fairly gentle using the zips as I can imagine the material could easily get caught in them, but this is very much the case with all the sleeping bags I have used, so no negative there. Also, very easily packs back into the compression sack for storage, no morning wrestling match with this one. What more can I say? Comfortable, lightweight, warm... and packs away easily. Highly recommended.

### ⭐⭐⭐⭐ Superb product, needs instructions for storing in bag provided.
*by M***R on 26 July 2016*

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!
