The thermal set is warm, but the top is a little short for my torso.

Perfect for cold weather layering! This thermal set is lightweight yet provides excellent warmth. Very comfortable and stays in place throughout the day. I’m happy with this purchase.

Warm and comfortable, but the waist could be a bit higher for better coverage. Good choice for layering on colder days.

Very nice thermal set. It keeps me warm, though I wish the top were a little longer. It fits nicely under clothes, and the material feels good.
