Comfort and warmth
Review by lindsay r. on 16 Jan 2025 review stating Comfort and warmth
I really love Smartwool products, especially the classic all-seaon merino base layer boxed long sleeved shirt. I have a few of these in my collection and wear them to walk my dog. They are light and soft to the touch. I can simply throw on my winter coat and head out knowing that I will be warm despite the cold temperatures outside. They wash well...Read MoreRead more about I really love Smartwool products,
and keep their elasticity. Highly recommend! Read LessRead less about I really love Smartwool products,

Excellent base layer
Review by Christine F. on 2 Feb 2024 review stating Excellent base layer
I like the long body for tucking in and the feminine cut. It is light enough to wear under other layers yet comfortable on its own. Great quality and weave. I will be getting more.

Fais bien, transparent un peu
Review by Melissa D. on 19 Jan 2024 review stating Fais bien, transparent un peu
Taille est bonne, confortable, flexible. Mais un peu transparent. Jai choisi couleur pas trop pale pour cette raison

Warm and Comfy
Review by Michelle J. on 1 Jan 2024 review stating Warm and Comfy
Sizing chart suggested I was between a 3X and 4X, went with the 3X and it is perfect, fitted but not tight. Ordered this top of outdoor activities this winter and love it! I've worn it on two short hikes so far and despite perspiring, was still comfortably warm and dry at the end of each outing. Highly recommend and will be ordering another.
