### ⭐⭐⭐⭐⭐ Review
*by S***N on 1 January 2026*

I’m quite impressed with this! Very soft and I really like certain accents like the way that the cuffs on the pants and the sleeves taper down to retain some heat better but to fit well either way gloves/boots, to make sure it isn’t in your way, just draped very nicely. The fit is snug, but not tight or restricting at all, and the merino socks are very nice. I’d say overall this isn’t the softest merino wool I’ve ever felt, other luxury dress brand fabrics are softer, but not they aren’t trying to do what this is trying to do, I’m comparing fashion to this technical, earth focused, based layer. And I think it’s soft enough for continued use without any irritation. I cut all the tags off and have gone on two 1.5 hour winter hikes in Canada and have been super comfortable. So far no odour, been great, and I even am enjoying wearing then around the house. Great buy especially for the money!
