My New Favorite Shirt

Incredible design and fit! I've been wearing the isotrope as a ski base layer for a few weeks, and I've loved everyday so far! A sleek and flattering fit with longer sleeves that I can tuck my hands into when they get cold. I wear a medium, and it fits perfectly. If you would rather a loose fit, then you may want to size up. Perfect for all activities, I'm already looking forward to wearing this for biking this summer!

The all occasion, all season shirt

The sleek design and endless comfort of this shirt has been a game changer for me. I was lucky enough to get my hands on this shirt in early February and mainly used it under my layers for ski touring. It fit nicely under my bibs and was cool yet warm enough to support me in my uphill skin. The thumb holes were a great addition when I was too warm to wear gloves but too cold to not have some coverage. I fell so in love with this shirt while touring that I had to give it a go as an around-town essential. Not only does it have a super flattering cut and comfy mock neck, but I have the option to dress it up under some overalls or with jeans, and the option to make it casual as a yoga LS or around house doing chores. If you are looking for a looser fit, I would recommend sizing up as this is a form fitting shirt. I'm 5'9" typically wear a women's L and opted for the XL.
