Re: Good sleeping bag for sailing
I recommend the Gauss Marine Sleeping Bag. It's layered with fleece inner and the synthetic fillings work if they get wet - unlike down-filled bags!
The Gauss bag is sold in the UK as Gauss is a British company, but they can be persuaded to ship the the US and Australia. Prices are about £189.95 ($320).
The bags are very warm when both layers are used and I know many that have never used the inner fleece layer. Personally, for sailing in cold climates, the Gauss is a very welcome, warm and comfortable treat!
