I only know warm weather. Winter here is a day or two of frost on the grass, then back to the upper 50's by 2pm.

My go to kilt year round is the one in my avatar. 13oz, 7 yards in MacGregor Tartan.

I have 3 other kilts, a PV, a cotton twill, and a 16oz wool... but there's nothing like my 13oz for comfort and style in the tropics.

edit: In the summer, flip flops are part of the dress code in Florida. Be prepared to show off some leg, since you won't be wearing kilt hose with your flops.
