Description

Who it's for
- Schools and rental centres that need very tough wetsuits.
- Intensive use in summer or in warm water.
- Anyone looking for a simple, durable wetsuit, in kids' and adult sizes.
Features
- Flat_Lock seams: the neoprene panels overlap and are stitched together, a very strong yet flexible seam.
- Double-lined neoprene and GBS seams for good insulation and a long service life.
- Supra_Tex reinforcements on the knees, the area that rubs the most.
- Nylon tape on the inside of the calf that protects the neoprene when you put it on.
- Different-coloured inner and outer lining and the size printed inside and out for quick identification.
- Composition: 80 % neoprene, 20 % polyamide.

Frequently asked questions
Which size should I choose?
Go by height and weight, and check the chest. A wetsuit should fit snugly so water doesn't get in; if you're between two sizes, choose the smaller one if you're slim and the larger one if you're more heavily built.
How are sizes told apart at the school?
Each size has a different colour on the inner and outer lining and the size printed inside and out, so they can be recognised instantly on the shelf.
