Versatile Piece
Review by Patrick K. on 5 Feb 2025 review stating Versatile Piece
I know this is a baselayer, but I often wear it as a mid-layer with a slim fit Smartwool tee underneath. Makes for a good combo with a contrasting tee, and is great for travel as it breathes well and can be worn many days without odor. Overall, a good item.

Great base layer for colder days
Review by Cristian C. on 1 Feb 2025 review stating Great base layer for colder days
Another great product from Smartwool. It is very warm and soft. Whether you wear it directly on the skin or on top of a t-shirt it always feels good. Much better than the polyester or nylon base layers. Highly recommended!

Ce chandail a de la classe, même pour bouger. Je l’ai offert à mon conjoint. Il fait cintré. Il est doux et se lave bien. On l’étend pour sécher

Review by james b. on 22 Jan 2025 review stating Smartwool Classic Thermal Merino 1/4 Zip Boxed Base Layer Top - Men’s.
My go to for active cold weather base laying. This one is my sixth! Soft and stretchy so moves with you. 1/4 zipper helps either temperature regulation. The large fits perfectly for me at 5’11”.

True to size/nice color assortment. 1/4 zip is great for ventilation. Only wish it came with pit zips too. Nice and soft next to skin.
