Men's Thermal Base Layer Long Sleeve Shirt

$40.00 USD

Reliable, comfortable, and itch-free companion on chilly days 

Finding a warm and comfortable base layer to go through winter that won’t trigger allergies or a rash can be difficult. This is because other thermal pieces use fabrics like wool, polyester, or Spandex that can trigger allergies and skin irritation. 

That’s why we developed an allergy-free thermal long sleeve for people with allergic or sensitive skin. Made with ultra-soft, 100% chemical-free, GOTS-certified organic cotton fabric combined with latex and Spandex-free ribbed cuffs, our thermal base layer long sleeve shirt keeps you warm and cozy without the rashes.


  • Relaxed fit with a honeycomb texture
  • V-neck design for a subtle look
  • Hypoallergenic ribbed cuffs without spandex.
  • Soft, ultra-fine, and breathable 100% organic cotton fabric 
  • Irritation-free label for sensitive skin
  • No latex and spandex
  • No chemicals, synthetics, and dyes

      Where has Cottonique been all my life?
      I'm in love with the feel of how comfortable the base layer is against my skin.

      Great quality

      Cotton is thick and soft and great for sensitive skin.

      Simple Ordering via Phone

      After failing three times to place an order on the internet, I called Cottonique. Ordering by phone was pleasant and very simple. I anticipate ordering more Latex and Spandex-free products from Cottonique by phone in the near future.

      great thermal

      very nice. I'm a woman and bought a small size. Covers my mid section and has long enough sleeves and nice cuffs on sleeves so they don't ride up. Superior to other long sleeve thermals I have bought. Very soft and comfortable.

      I am a woman and wearing the thermal underwear for men is roomy, comfortably soft.
      I wear them at night here in Washington State.

      Excellent product, warm and snug, and non-allergenic.

      Thank you!!!

      Your man and woman thermal long underwears are the best, warm and soft. We bought 3 sets for each of us. We love them. Highly recommend them.

      a perfect snowboarding companion

      I tried the men’s thermal shirt when I went snowboarding in Japan. It felt so soft when I put it on. I was surprised to see it keep me so warm even though it’s really just cotton. The material has some good stretch to it but there isn’t any elastic in it which is why I think it regulates body temperature a little better than that synthetic polyester spandex that you find commercially. Overall pretty good job with this one. I will be using it again when I get back to the slopes.
