Fleece Lined Thermal Underwear Set for Men Who Ride in the Cold

This men's thermal underwear set is a two piece base layer built for cold weather riding and winter work. The long sleeve thermal top and high waist long johns are cut from soft knit cotton with a brushed fleece lining, so they trap body heat next to your skin while staying breathable and light. Slip the set under your riding jacket and jeans and you get real insulation without the bulk of extra layers.

Frequently Asked Questions

Does the set run true to size?

What is the difference between the crew neck and round neck tops?

Both are pullover thermal shirts in the same fleece lined fabric. The crew neck sits slightly higher on the collar, while the round neck has a softer, more open neckline. Pick whichever you prefer under your jacket.
