Also note that they have the little chemical hand warmers for a few dollars . These are fantastic and can be re activated over and over again . I've had mine for years and are great to put in your pockets on a cold day sailing.
I did not get an Aldi jacket as I already had a good Burke wind proof jacket which I wear over a sloppy joe and that's ok. I think the jackets are good as my wife bought one and they are also quite cheap at $60. The only thing I would watch is that the jackets are not too bulky to put whatever you wear as a pfd over. The other bits and pieces like thinsulate beanies and scarves are also good for cold weather sailing. I have a neck band type scarf that can be used as a beanie or balaclava I bought years ago at bcf and it's the most useful bit of kit I have . I've worn it in Europe, Canada and Alaska in the cold, even night kayaking in NZ and even though it's only stretchy nylon it's very warm and holds your hat on while sailing

Usual disclaimers , blah blah.
Winter sailing is often the best time of the year, but I dont enjoy being cold. What do the rest of the forum have for cold weather sailing.?
