My old ?Blacks Polar? is great a 4 season bag that kept me warm in Glen Geldie one February when I needed a pneumatic drill to get the tent pegs into the frozen ground.
Fine, but an overkill for summer camping and it has no zip which is a pain. It is also VERY heavy and bulky to carry.
Right, I need a good summer bag, lightweight (I guess that means down) warm and compact to pack but not hugely expensive.
What should I be looking at?
