Excellent piece of kit
The Thermalite DRYSystem really is an excellent piece of kit. I've always been into drytops with gear underneath, but this 2.5mm top gets rid of the need for a spray/dry jacket and is a much less bulky option. Over the top of the Thermalite Longjohn this will take you through most normal winter sailing and should things get a little too fresh, stick a thermal top on underneath and you're good to go. Sailing in the Lennon supported Solo 5691, catch me for a chat if you see me at an event.
