Our tuilik is made out of a very stretchy, high quality neoprene, 3-4mm thick (depending on stretch). You can choose either the same size you would use for other brands or choose a size smaller to get less pooling of water from too much fabric around you in your kayak. Also, the hood gets tighter for smaller sizes. If you have a small-ish head, go down a size (or even two).
You might have preferences regarding fit of course but the sizes are physically about 1,5-2cm taller cut per size. The bottom lip fits both ocean and keyhole cockpits up to size M-L, approximately up to 86cm cocpit length. For larger keyhole cockpits, it might fit depending on the lip with of your cockpit.
Think of the sizes approximately like the below:
- >190cm = size XL
- >180cm = size L
- 165-180cm = size M
- <165cm (<170 women) = size S
- <160cm = size XS
