Merino wool at its finest.
As expected, this merino wool is super comfortable. The fit is just right and insulation value is perfect (not too warm or too cool).

Pretty Upset
Ordered this item in this color and size because it was listed in stock. 9 days later, I get a notification that the order was cancelled because it’s no longer in stock. WTF? Tried to order a new base layer set for my son for Christmas. Now I’m getting a notification in the 11th hour that my son is only getting a pair of leggings right before Christmas…pretty irked by the customer service here.

Great shirt for camping
Comfortable and can wear it a long time without having to wash

Shirt is true to size. Comfortable and super warm. Used snowboarding and camping. Slightly scratchy if you aren’t used to wool but easily forgotten in a few minutes.

A definite base layer only, but a good one at that
Great product. Comfortable and will perform well as a merino base layer (sweat mitigation, anti stink, etc). However, it’s definitely only a base layer. The neck is cut very wide and doesn’t sit like a causal t shirt. The length of the torso is short as well. Slim fit is fine as again this isn’t a casual/baselayer combo…just a baselayer. Their 150 tech tee is perfect for everyday wool wear so I am going to invest more in those than this product as wool base layers have a very specific use case.

All round solid layer
I wear this layer other than hot days of summer. I pair it with a wool hoodie on cool days. I work in it, I hunt a lot in it. Ski in it all winter. Breathes really well while still holding heat. Doesn’t hold odor. First time buying this product and will buy again.

Must-have base layer.
I use this base layer almost daily here in the PNW where the fall through spring are cool and wet. Doesn’t retain body odor, and maintains comfort and insulation with regular washing.
