Stop Settling: Why Your Regular T-Shirt Isn't Cutting It as a Base Layer
Are you tired of your typical t-shirt failing to provide the comfort and functionality you need? It's time for a change. Let's face it: relying on a regular old t-shirt as a base layer just doesn’t cut it. Whether it's inadequate moisture management, lack of odor control, or discomfort due to seams and tightness, your current go-to isn't up to the task. But fear not! Upgrade to a base layer that offers seamless design, moisture-wicking magic, and a fit that flatters. Say goodbye to compromises and hello to ultimate comfort and performance.

Here's What Our Customers Say
I Love the fit and materials of my Numi classic shirt. It really protects the outerwear sweaters and jackets and other long sleeves from my sweat.. That says a lot.!!

I had a blouse that showed perspiration stains - it was frustrating to use adhesive pads. I am beyond happy with my signature undershirt. It is lightweight, comfy and works to prevent perspiration stains, just as advertised. Best part? Canadian company and made in Canada!
