The Defence 4 is the most popular and best-selling all-round sleeping bag with excellent weight to stuff size and performance ratio. It is a well-established, 3-season sleeping bag that has proven to be 100% reliable on cold nights both in the wilderness and in snow caves. A protection flap on the outer side of the zipper keeps out wind and wetness.
The outer shell is a super-light, highly resistant, microfibre nylon with a fine microporous coating which makes it water-repellent. There is a generous draft tube on the inside of the zipper to prevent heat loss at the zipper.

The zipper in the middle takes some getting used to. The stickers keep the windbreaker in place. The mouth opening is quite small even at its widest. On the other hand, you can also tighten it around your neck and sleep with your head out. The compression bag is great and you can make it really small, Defence 1 / Tropen size. I'm 180cm/90kg and I fit into the smaller M size bag just fine.

It feels high quality and the zipper works well. It's suitable for use in sub-zero or slightly cold weather when you wear an underlayer. An inner bag would make washing easier, but would add weight and size. At least after a few nights of sleep, it doesn't need washing yet.
