I got it at a Marine supply store in St. John's Nfld. The store is Campbell's Ship's Supplies, box 274 St. John's A1C5J2
It's made by Mustang (Mustang Survival 3810 Jacombs Road, Richmond B.C. 604 270 8631 firstname.lastname@example.org
) lists at 399 and I got it for 319 (Canadian obviously) There are other brands but these are good quality.
It's like a snowmobile suit, except more lightweight, sealed with neoprene wrist cuffs, head cover that seals nicely and it of course has flotation so you end up head and shoulders up, if you go in the drink. It has lots of reflective tape, and most important it is comfortable and easy to put on and take off.
It is very warm, although we have had a warm fall so I can't say what it's truly like.
It looks a bit bulky, but when you have it on, it tightens up with some straps in the waist and the legs. It's important to tighten these straps as it pushes out air so you float head up.
It's not a neoprene wesuit. They are what we used to wear windsurfing in my misspent youth. They are restrictive, damp uncomfortable, etc..
Having said this you can get less expensive ones that will probably do a good job, however I am 50 and the idea of freezing in the water to save some moolah is not in the cards. I want my wife to see that I have a few clues.
For gloves I tried my windsurfing gloves but they had no grip so I got some of the cheap yellow/orange thin work gloves with some plastic sprayed on to give grip. Check out windsurf or dive shops for warmer gloves.
Hope this helps!
PS My friends and I used to do a windsurfing afternoon on New Years Day in the Atlantic off of St. John's Newfoundland every year.
