The time has come .... my old Mountain Equipment bag (PW in 1981) and Snugpak (round the world tour in 1996) and both on innumerable Munros, backpacks and car camps are tired and worn out - a bit like their owner.
I've seen some 3-season Berghaus and Vango bags on Blacks website https://www.blacks.co.uk/equipment/sleeping/sleeping-bags/
Should I open the wallet and let the bats out - or think again? I don't need a super lightweight job for Antarctica. Mostly just spring/summer/autumn in the UK - assuming we're not all locked into our homes, of course.
