"Awesome shirt. The material and fit are perfect."
Built for adventure, designed for comfort. The Yukon is the cozy brother to our best-selling Jung Long Sleeve Tee. Same classic fit, but made from a soft hemp / wool jersey.
Women should typically size down, but fit is best determined by referencing the size chart. 'Men's Sizing' indicates sizing based on standard garment manufacturing terms, and is not meant to suggest gender identity.
The finished garment is washed in color, rather than dying the fabric prior to cutting and sewing. This results in subtle variations of color and a softer texture. Washed White is not garment-dyed.

Hemp is a naturally strong, durable fiber, which is why we use it to make clothing you'll wear for years. It's also a remarkable crop: in the right conditions, it grows with relatively little irrigation and fewer chemical inputs than cotton.
The facts:
Stronger fiber than cotton. In a peer-reviewed comparison, hemp fibers measured 310–850 MPa in tensile strength, compared with 287–597 MPa for cotton. [BioResources, NC State University]
Resists pilling and wear. In 2025 lab testing of woven bast-fiber fabrics, hemp earned the highest pilling-resistance rating of the fabrics tested, holding up across repeated wear cycles. [Fibres & Textiles in Eastern Europe, 2025]
Uses less water. Hemp uses about 38% less water than cotton over a growing season, and its water footprint is roughly 60% lower. [Journal of Agrometeorology, 2023; Journal of Cannabis Research, 2025]
Needs fewer pesticides than cotton. Cotton is one of the most pesticide-intensive US field crops, with 42 million pounds applied across 10.3 million acres in 2021. Hemp is typically grown with substantially less pesticide input. [USDA data via Organic Trade Association]
Captures carbon as it grows. Published estimates put hemp's CO₂ uptake at roughly 3–15 tonnes per hectare during cultivation. At the higher end, that outpaces the 2–6 tonnes per hectare per year typical of forests. [Portland State University review; University of Cambridge research]
Can help clean soil. Hemp roots can absorb low levels of heavy metals such as cadmium, lead, and zinc from soil. This process is called phytoremediation. [Portland State University review]
Facts refer to hemp fiber and cultivation. Many of our garments are hemp–organic cotton blends.

"Awesome shirt. The material and fit are perfect."
"Nice material- softer than another hemp/merino Jungmaven shirt I have. Fairly thin but a great layer for wearing under wool sweaters. I sized down but wish I went with my regular size."
"The Yukon Long Sleeve Tee has become one of my closet staples -- soft, light, and versatile. It works well solo, of course, but is great under a long-sleeve button-up or even in tandem with a short-sleeve Jung Tee of an complementary color."
"Warm but breathable, soft and stretchy. Thin to layer under a sweater or light jacket depending on the need for extra layers. The hemp is a little rougher than a full merino wool, however I can tell from the first few washes these will last longer than a cotton and merino wool the fabric is tougher. Which makes sense and why I went with the hemp. Overall very happy to replace my cotton and merino under layer shirts from many different companies I think with the Jungmaven shirts."
"Nice quality and love the fabric content"
