    Great for outdoor winter activities

    Published by Plot Trysts on Dec 28th 2025

    These are great leggings for outdoor activities, either as their own layer or as a base under a snowsuit, for skiing, hiking, etc., and also as pajamas! The color is really pretty. Love the lightweight wool, too.

    This is a nice base layer but was pretty pricey, I wish it came as a set.

    Great quality

    Published by Rosie on Dec 8th 2025

    I love wool for staying warm. I ordered for my 6 year old grandson, and they fit well. He's a bit tall for his age so I'm hoping they fit 2 years. Even if they don't, these pants are 'hand me down' quality. Once he outgrows them , they'll go into the drawer waiting for our next in line grand child to grow into. He really liked them, they are definitely soft and I wanted to see if he thought they were itchy, and they aren't. He put them on and kept them on before going out, then when he came back in from outside, he just took off the outer layer and chose to just hang around in his new 'long johns'.
