Which Cuddl duds are the warmest? Which cuddl duds are the warmest? The Cuddl Duds Fleecewear With Stretch and Thermalwear collections are the warmest. My personal favorites are the Cuddl Duds Fleecewear with Stretch Leggings and Cuddl Duds Fleece with Stretch Long-Sleeve Top.
Are Cuddl Duds really warm? In terms of warmth, I prefer this brand to the Duofold. Cuddl Duds is slightly warmer, more lightweight, and my jeans slipped right over them with no problem. They are very silky and nice!!
