[rifmaniac]

I hunt in Tunisia, but it does get rather cold in winter and I'm quiet chilly.
I hunt with a 7mm Beuchat wetsuit, and I've stuck a 5mm layer of neprene at the back: its narrow on top (to fill the interscapular region) and wide at the bottom (for the lumbar region); I also put cycling shorts over the wetsuit to prevent water from getting in from under the top of the wetsuit.
Once the main part of the body is warm, hands and feet should be ok.
