    Snug over the parts it covered

    Autumn kayak fishing in Scotland in a stiff breeze. This pursuit can require a lot of sitting about without moving. For this I was kept warm despite the cool October breeze. With my legs over the side for long periods I didn't feel any cold. The parts not covered did get cold after a bit over an hour wearing a Vaikobi Flexforce 1.5mm top, though I would have been fine if active, most likely, but I hope that shows that the extra thickness ensured extra warmth. I never needed to pee using the excellent new addition of the relief vent, but that'll come in time. A comfortable fit & easy to move around, good purchase for Scottish waters.
