Swedish Thermotic AB manufactures fantastically comfortable underwear that both warms and floats. The thermal properties mean that you retain body heat longer if you end up in the water.
With these super thin garments, there is no excuse not to wear buoyancy aids! Suitable for kayaks and boats in summer and on the ice in winter.
We have a sample ladder in the store if you are unsure of the size. Generally, the size is about 1/2 size smaller than Swedish standard sizes.
