An instant “Go to”
At 5’9”, 165lb I was between sizes; returned the medium for a large (exchange was quick and easy). It is my go to base layer. Very happy with all my Ornot kit!

Killer base layer
Unbelievably good base layer. I use it biking, running, even took it up mt Washington last week for a mountaineering adventure. It's been cold so I have used this as my first layer with a long sleeve merino on top, but excited to use it in shoulder seasons as a solo base layer. I think it will be super effective. Highly recommend

Great base layer, and probably the only one I’ll buy now. I’ve used it in every challenge the bay has thrown at me and it’s held up great. Super comfortable for long rides, or not.
