Given the tripe I came up with reviewing other bits in the same order as this I’m surprised you want anything more from me, but here goes. For fourteen pounds you can buy this, it’s light, decently made, got room to move about without trying to give you a strangulated hernia. It will last. Or you can buy a similarly priced bag from couple of high street stores, probably as warm, bout same size, but fall apart in fairly short order. Only thing is it smells a bit of storage when you get it. Couldn’t be bothered to wash it, hung it on the line in the sunshine. Soon it will smell like me!
