A long sleeved men's quarter zip sweater, designed as a mid layer.

Our Stratam LS Sweater combines 46% yak wool for its superior thermal properties with 42% durable and eco friendly DuPont™ Sorona® biopolymer for a smooth external surface.

Our Hima-Layer™ Stratam fabric is made with a combination of two yarns. On the inside the 100% yak wool yarn knitted in a terry loop construction traps air for warmth and provides excellent wicking properties. On the outside, we’ve used biodegradable DuPont™ Sorona®.

DuPont™ Sorona® is a biopolymer yarn made from corn starch. It creates a smooth surface which offers further protection from the elements.

Giving back to the Himalayan nomads

kora was founded with the aim of supporting the communities of the Kegawa Herders' Cooperative, by buying their yak wool directly to create our layers.

A collective of more than 90 families in the Yushu Tibetan Autonomous Prefecture, our friends live all year around at 4,500m.

We buy this wool at a set mid-market rate throughout the buying season in order to offer price certainty, and in addition we pay a 10% stipend.

Well constructed sweater, side panels allow a lot of range of movement . Colors that kora outdoors has are vibrant . Temp range that Stratam covers is amazing . Fit and Fuction is off the charts

I bought it for my husband for our trip to the Aleutian Islands.

Perfect mid layer, pinnacle piece

I’ve been on a quest for some years to find the perfect mid layer. I’ve amassed well over 20 fleeces, vests, and wool pieces. All are great, but the Stratam LS Sweater is head and shoulders above them all. Here’s why.

I invariably end up wearing my gear indoors a lot. The temperature range/regulation on the Stratam is truly amazing. I balked at buying it for a couple of years due to its 350gsm fabric weight. I feared it would be way too warm as my 200 weight pieces are often too hot. I’ve never had that issue with this piece. Also it layers as well or better than my thinner super fleeces while providing substantially more warmth.

While I like a full zip they always feel like wearing a jacket to some extent. The deep zipper on the Stratam provides sufficient venting while retaining the comfort and coziness of a pullover. The sleeve length is perfect and the sleeves push up and stay up comfortably. Plus the collar has a perfect height, snugness, and flexibility, and lays down nicely when zipped down a bit.

Wearing a great piece while not looking like you just came off a mountain or being a billboard for an outdoor company is a definite bonus. The Stratam toes the line between casual and performance gear perfectly. I mean it looks good. The color is rich, the texture is luxurious, and the craftsmanship is top notch. Seriously, I feel like a king when I’m wearing this. I was unsure about the pocket but I’m finding it unique and a good place to store a handkerchief or light snack.

I will say I’m almost always a solid large, and although the size chart recommends an XL for me I went with the large and it fits like a glove. I’m a proportional, athletic 5’11”, 185# guy with a 43” chest for reference.

It’s long enough to be tucked in and also looks good out. It’s just a class piece through and through. I’ve purchased a second so I’ll always have one on hand. Thanks so much Kora. Well done indeed.
