What thermal underwear to use under a dry suit?
Unambiguously, this is the underwear you will feel most comfortable with for the specific water temperature. It sounds simple and logical, but in order to reach the underwater nirvana and successfully complete the dive, we need to follow some rules:
- For better comfort, it is better to be slightly cooler than slightly warm. We dehydrate from the heat and also increase our heart rate, blood pressure and put our patience to the test.
- Do not use natural fabrics. They do not bring moisture out, and in the case of a suit, they retain water, become extremely heavy, and worsen its thermal insulation properties.
- On the contrary, the multilayer hightech 3- or 4-layer thermal suits work perfectly, even when completely wet, retaining over 80% of their thermal insulation properties.
- The best materials not only do not lose their properties when washing, but even increase them after 4-5 washes. They are usually made up of 4 different layers, one of them being hollow synthetic fibers. In spite of they are very fat, they do not want a lot of extra weight, have light weight and heavy pay. ????
- Multilayer Dressing – The most versatile and inexpensive option where you use different linen on top of each other depending on the instantaneous water temperature. Thin ski or motorcycle thermal underwear, combined with polar or tinsulite products, are cheaper and very comfortable for multi-layer dressing.
- Tinsulaite materials are the warmest, but gradually lose their properties with each wash.
- The cheapest and warm are ski overruns, but they are uncomfortable because they boil and lose 40% of their properties when wet and require more weight.
And as one Bulgarian poet said: “everything good under one roof does not grow or there is a passenger for every train”! :)))
