100% Organic Cotton

With its warmth, comfort, and extra insulation, this base layer bottom surely deserves a space in your wardrobe. Made with 100% chemical-free GOTS-certified organic cotton fabric, this thermal base layer long john with fly serves as a second skin that protects men from cold and irritation. It's not too tight and not too loose, so you can always be comfortable and itch-free wherever you go

Warmest base-layer bottom with allergy-free comfort 

  • Supporting the daily routines of men who are always on the go
  • Layering when temperatures drop during the winter seasons
  • Keeping your body warm and comfy without constrictions and discomfort 
  • Avoiding irritations caused by textile dyes and elastics, such as latex and spandex 
  • People with contact dermatitis, eczema, psoriasis, carba mix allergy, or multiple chemical sensitivity

Note: The latex-free and spandex-free elastic that we utilize in some of our products contains a white rubber tape wrapped in 100% organic cotton. Made with one-third the thickness of standard rubber, it achieves that stretchable feel and ensures an itch-free experience without natural rubber latex proteins that cause allergy symptoms. If you're unsure about our elastic and its potential effects on your skin, you may opt to check our Allergic Contact Dermatitis collection.

Insulation and comfort are important to support your daily outdoor activities under low temperatures. We never fail to add those features with our Men's Thermal Pajama. This hypoallergenic thermal bottom functions perfectly as an efficient base layer or comfortable sleepwear. Slip into this piece and allow 100% organic cotton to make all the difference.

Layered Comfort

These have become a favorite of mine in winter for layered warmth and comfort. I liked the first pair I purchased and reordered a second pair to rotate when laundering the first one.

Excellent comfort and warmth

Several years ago I was advised by my dermatologist to wear hypoallergenic 100% cotton underwear. I had been wearing briefs, and the boxer brief style appealed to me. I bought a number of the drawstring style and liked them. When the elastic style was introduced I tried them and like them better. I just ordered four more. Five Stars!

WOW, just wow!!

These are the absolute best pair of thermals I have ever owned! They are the thermals I have always wanted. They are thick and all cotton, and so absolutely unbelievably soft!!!

The stitching in them is also unreal! I never understood the true craftsmanship that goes into a garment until getting quite a few cottonqiue items and this one is no different. Your legs bend, and everything is still comfy all around.

Love them, I had to buy a few pairs cause I didnt wanna take em off!

Excellent comfort and warmth

Just the right amount of room for me to stretch and feel comfortable. Fit's well under jeans and work cloths. Very comfortable against the skin and has held up really well with repeated washings. I own a few pairs so I rotate them all the time especially with our winters here in northern VT.
