Lightweight Next-to-Skin Performance

Build your day on a solid foundation with the K1 - Primus Long John baselayer. Merino wool with a synthetic coating 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 closure provides support and fuss-free access (even with gloves).

Beyond Wool

Polyester fibers and a synthetic coating take our warm, moisture-wicking merino wool to the next level, increasing wool’s natural durability, preventing shrinking when washed, and speedily evaporating mopped-up sweat.

Package Deal

The Ballhalla™ fly keeps you comfortable all day long with anatomical support and minimal bulk, and the unique closure design ensures easy access even while wearing gloves.

Fuss-Free Foundation

Flat-seam construction ensures all-day comfort, delivering a smooth next-to-skin feel and reducing bulk when layering up.

Great product, logistics off

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.
