M's Thermalrunner Insulated Jacket

For how thin the material looks and feels it insulates so well. I wish I had bought this in December/January when the temps were consistently near 0°. Highly recommended

Wore this in single digits Massachusetts winter this year with just a merino wool shirt underneath, was plenty warm. Incredible insulation at such a light weight.

When this arrived I was initially skeptical because of how lightweight it is, but I have yet to use it in temperatures it couldn't handle. My current rule of thumb is that it gives 30+ degrees of warmth (i.e. if its 20 outside I should wear what I would wear for a 50-degree day underneath it). Really impressive insulation and the white artistic design is also fun and high-visibility. Glad I opted for a Medium, it's a little big but works perfectly for layering. New favorite winter jacket. Haven't tested it in precipitation or very high wind.

I’m 6’2”, 180 lbs and the large fits perfectly. Have worn this for about 10 long runs now - several in the mountains when it was 20 degrees F and windy. This jacket does the business. Cozy without being hot. Mine is a mustard-y yellow color that’s plenty visible without looking like a safety vest. Also have a couple LS running tops, some tights, and a couple trail running shorts from Janji. Rapidly becoming a fan of this brand. Keep up the good work.

True to size and warm

Great winter run temperature control and light weight

Did 13 miles in this jacket this morning, real feel 4 degrees, with just a long sleeve t under this. Was never cold but also never hot. Crazy how something that feels this light can stand up to winter runs.

Great winter weather running jacket, soft material, warm yet breathable

I also have made a youtube and ticktock review of this while I am running in snow storm in jersey city temp 30 degrees . The jacket holds really well and fits true to size. The yellow color is amazing. Very light jacket with perfect warmth.
I had two layers underneath the jacket. One thing and one thick layer, as I get cold really quick.

It’s light and breathable. I usually wear small and this has enough room for layering something underneath. Wore it with a T shirt and wool full sleeve jumper in 20-25F run and it was comfortable after the first 5 min.
