Lightweight Next-to-Skin Performance
Build your day on a solid foundation with the K1 - Primus Long John baselayer. Wool balanced with synthetic fibers delivers long-lasting durability, simple wash cycles, and the fast moisture transport your layering system needs. Flat seams ensure bulk-free layering, and a specialized fly provides support and fuss-free access (even with gloves).
Our wool combines with synthetic fibers to create the ideal performance fusion for moisture management: wicking up and lifting out sweat, protecting against odors and wash shrinkage, increasing durability, and ensuring next-to-skin comfort. Your system’s moisture transport starts here.
The Ballhalla™ fly keeps you comfortable all day long with anatomical support and minimal bulk, and the unique design ensures easy access even while wearing gloves.
Flat-seam construction ensures all-day comfort, delivering a smooth next-to-skin feel and reducing bulk when layering up.

Exactly what I needed out of a warm base layer. M its very close to the skin on a 5'10" 190lb "athletic" body.
I like the feel of the fabric along with the waist. I wish it was a little tighter around the calf’s but that maybe just my personal impression. I like the blend doesn’t get smelly even when wearing for days in a row.
Was looking for a pair of long johns that were comfortable enough to wear under work pants all day and not be too tight fitting and keep me comfortable inside but not let me freeze when I went outside. These were perfect! Will be ordering these again!
The base pants are very comfortable
The base layer I ordered worked like a charm. It kept me dry and warm. Unfortunately it took over a week to ship after I placed my order. It took almost twelve days to actually receive the product after I ordered it. I would expect in this day in age, with shipping technology, that my order can be shipped and received in a more streamlined, expedited process.
