Womens Thermafleece 4.0 Top and Bottoms

I got this gear to wear to Maine. Its is nice quality and looks like it will be very warm. For sizing I woild say size up. My only negative comment is for me, a person with a long torso I wish the top was longer. I prefer to keep bottom layers tucked in but I wont be able to with this. Im still keeping it.

Warmest Base Layer Ever

Love this base layer (both the crew top and the bottoms). So warm and cozy. I can wear the bottoms on their own in single digit temps, and don’t even need to wear another layer to stay warm (besides a long coat).
