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).

Beyond Wool

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.

Package Deal

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.

Fuss-Free Foundation

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

Perfect for Backpacking

Have now taken these on a couple camping trips in Colorado at around 9,000 feet and they are a perfect for a comfy camp layer. Have worn them under my hiking pants on colder nights and under shorts in the cool mornings while making coffee and breaking down camp. Plan to use them under snow pants on colder winter days for snowboarding and I’m sure they’ll be a perfect blend of warm and breathable. For the price, I’d buy these and other Beyond items over comparable Patagonia/North Face/Outdoor Research gear.

K1 Long John

I have purchased a couple of pair of these. Great fit at a good price. I wore them this past weekend on a camping trip, Friday night got pretty cold and these helped to keep me warm. Great quality as I have come to expect. I see these serving me well for years to come.

Great early season base layer

I wore the Primus K1 long John on a turkey hunt last week. Temperatures in the morning were in the 30s. Midday temperatures in the 60s.
This base layer kept me comfortable all day

Sweet long john

Love this. I haven't had much time to use it (the time of year) but top notch construction that I know will last a long time.
