I have a 7mm Arctic SGS full suit and a 7 mm Arctic SGS hooded shortie as well as a pair of coldwater kevlar 5mm gloves, and love everything. Fits well, stays very warm, and it is good looking suit as well. Having used both the SGS and the non-SGS suites, i recomment the SGS drys in a snap and is easier to put on by a long shot. If you can afford the extra dough, it is worth it for sure. I think they are discontinuing the SGS line after this year, but i am not sure about this. A rep at BARE mentioned it to me on the phone earler this year, but i am not sure if they are just going to call the line something else or get rid of it.
Bottom line: I recommend.
