If you wind up buying a dry suit, look into getting zip seals that you can change out wrist seals and dry gloves before you complete the purchase. They can prove expensive to add later and you will probably need to send the suit off to have them added. If you are just looking at thicker neoprene gloves, I strongly recommend that you get a good fit and make sure you don't lose too much dexterity. Also, keep in mind how the gloves will mate up with the wrist seal on the dry suit, some gloves come too far up the arm to work well with dry suits.
