Donning the drysuit

First remove your watch as it could tear wrist seals, lay the suit out flat and do a quick 

overall inspection to ensure it is in good order.

Dust the inside of the latex seals with Northern Diver Talc or lubricate the neoprene 

seals using Northern Diver Drysuit Seal Lubricant (supplied in the maintenance kit).

Lubricate the zip with Northern Diver Zip Wax for BDM drysuit zips (supplied in the 

maintenance kit). 

Remove all jewellery – sharp edges can destroy the seals.

Fold the torso of the suit inside out over the legs to about waist level, so the braces (if 

equipped) are exposed.

Make sure the braces (if equipped) are correctly attached, and are not tangled or 

twisted.

Sit down if possible and insert foot first into the suit, making sure you do not tangle 

foot in braces (if equipped).

Grasp suit material at calf level and gently ease foot into boot. Pull up on leg.

Repeat with other leg.

Grasp torso and ease suit up so that the crotch of the suit is correctly positioned.

Raise braces (if equipped) over shoulders and adjust so they support the weight of the 

suit.

When present, fold the neoprene outer cuffs back away from the seals.

Insert first arm all the way, taking care with the seal when pushing hand through.

Repeat with second arm. Try to make sure the inside zip flap is not curled under during 

this process. Make sure that if the drysuit undergarment is equipped with thump loops, 

they are fully retracted, and not caught between the seal and your wrist. This will cause 

a leak.

Grasp the top edge of the neck seal with both hands, fingers on the inner surface, 

thumbs on the outside. Make sure your fingernails do not tear the latex or smooth skin 

neoprene. Spread the opening wide enough to draw the neck seal over your head, 

and adjust so it is comfortable. (Note: some divers prefer to don the neck seal first, 

inserting the arms after. This is a matter of personal preference).

If you have long hair, you may find it easier to wear a nylon stocking or similar over 

your head when pulling your head through the neck seal. If your drysuit has a neoprene 

neck seal, the neck seal should be inverted so that the smooth side is in contact with 

your skin; this forms the seal. Have your buddy make sure the drysuit undergarment is 

correctly positioned under the seal so that there will be no cold spots.
