So Cozy
"The fabric feels like I’ve owned it for years, it’s so soft and cozy. I normally wear a large but the medium fit me perfect."
Rugged and ready for the adventure. Get one before they are gone. For when the mountains are calling. “The clearest way to the Universe is through a forest wilderness” – John Muir; My First Summer in the Sierras.
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.

"The fabric feels like I’ve owned it for years, it’s so soft and cozy. I normally wear a large but the medium fit me perfect."
"I love all Jungmaven sweatshirts! This one is nice because it has a nice weight and fits true to size. It feels like a real sweatshirt not thin like many other brands. The length is perfect as well! Buy it!"
"This is a comfy lounge shirt. I love the raglan shoulders no pinching around the armpit with this design. I was worried the sleeves would be too short, but they were pretty perfect. Definitely an oversized fit. The thickness is good I don’t like thin winter shirts and this was definitely thicker and worth the money."
"I love this sweatshirt! Perfect for cool southern California mornings and evenings. Only issue is my wife might love it more than me and keeps stealing it. Guess I gotta order another color :)"
"The neck and hemline are a bit baggy. That may be your preference but I prefer a fitted neckline and cinched hem"
"Love this sweatshirt so much, I already owned it black and needed a second one. Perfect weight, heavier than a long sleeve but not quite a sweatshirt"
"This is like bypassing the time when a new sweatshirt is all stiff and going straight to the worn in stage. I love it! I got the poppy red and to me it’s a bit more orange than it looks online but it’s still a great color."
"The Sierra is a favorite. The fabric is silky for a fleece and has a nice weight with slight drape. This combined with the raglan sleeve makes for a comfy, flattering fit that can look discreetly elevated."
"Sierra raglan sweatshirt is my new favorite. So comfortable and warm, but also breathable. I could wear it every day and I think it would work for spring, fall, and winter. I ordered a L (I’m xl in Women’s) and it’s roomy. If I wanted it more fitted I’d go down to a M. I will be ordering another one."
"My favorite Jungmaven sweatshirt - buttery soft and flattering fit. The sleeve hem is supple and roomier - much preferred. Great weight for cooler months. Would be better if bottom hem wasn't so wide, or make a cropped version. Love the colors!"
