    These wool base layer pants are so soft and comfortable! The wool isn't itchy at all feels like really great quality wool! It fits my son exactly how I had expected based on the size I got him. It definitely helps him stay warm when doing winter activities to wear this under his snow gear. Overall, a great value for such a versatile clothing item!

    Soft

    Published by Lindsey on Feb 22nd 2026

    My son has adhd and sensory processing issues when it comes to fabrics and textures. I was worried about merino wool being an issue for him as he prefers to wear everything dri-fit material, fleece or a very smooth and soft cotton. At first he complained when he put this base layer on, but after wearing it for a few minutes, he said that it’s very cozy. Bought as a base layer set for skiing as he runs hot and sweats easily. For the first time when wearing this base layer set, I took off his ski helmet to a dry head. It definitely helped to regulate his temperature and wick sweat. Very great product. Not surprising though as I loved the sleep sacks from Ecoable when my son used them.

    Arrived with a hole

    Published by Disappointed on Feb 22nd 2026

    The inner seam of the leggings had a hole in it due to a manufacturing defect when I opened the package. I paid more than $125 for the leggings and shirt and shipping. I was offered only a 15% discount to keep the item as is, or free return shipping label and full refund; Customer Service said I could not exchange them. I was really disappointed as I paid a lot and wanted to have these for a long time.
