If the paddler comes out of their kayak, a tuilik provides considerable initial buoyancy, and the legs may be drawn up into the air pocket.
[4] Quick-release suspenders were traditionally used to lift the front and prevent water from pooling in the excess length.
[5][6] The tuilik must seal at the face and kayak cockpit coaming, and usually at the wrists (unless there are integrated mittens, as in the tuilikusaq image above).
[4] Some kayakkers make tuiliks by sewing or gluing commercial drytops and sprayskirts/spraydecks together, with a permanent waterproof join.
[8][9] Traditionally, a tuilik can be made from specially-prepared seal-skin, sewn with sinew, with draw-string seals.
If it is dried in cold, dark, windy weather, it becomes opaque and white, and is known as "winter gut".
[3] Seams are avoided in areas where their bulk would make the tuilik stiff or cause water to pool, such as on top of the shoulders.
[17][18][19] Elastic cords (including leather thongs), and sometimes velcro straps,[17] are used to keep the seals in place.
The hood edge must seal to the face, and usually has a draw-cord that wraps 1.3 times around the hood opening, with the cord doubled at the top and exiting the casing through holes near the ends of the wearer's eyebrows before tying adjustably behind the head.
