Using a 3mm sailing long john is a solid middle ground for days when the water is cold but the air is mild. The lack of sleeves lets you reach for lines or handle the tiller with total ease. It sits comfortably under a spray top and offers just enough warmth for long sessions on the water. You can move freely around the boat, and the extra padding in the knees helps when you are moving quickly across the deck.
