Perguntas Frequentes

Should I also consider wind and session length?
Yes. Cold wind and multi-hour sessions push you one tier thicker. Also add booties below ~16°C and a hood below ~10°C.
What about neoprene types?
Yamamoto / limestone neoprene is ~15% warmer than cheap petroleum neoprene at the same thickness — you can drop one tier.
