Dolly, as we’ve written about elsewhere, is unique, new, and yet uniform. Almost like the cloned sheep of the same name. The Swobo Dolly Knee Warmers are replacing the more traditional Merino warmers because they’re warmer and more functional. Swobo has mated a wool inside to a nylon outside. The Merino inside is soft and warm and cozy. The nylon on the outside speeds wicking, provides a more windproof layer and has a tight stretch that keeps the warmer from moving. In other words, just the same as before, only better. Sizes XS-XL.
