M's Thermalrunner Insulated Jacket

Perfect fit and true to size. Quality construction in every detail. Warm! Very good value

When I pulled this jacket out of its packaging and felt how light it was, I thought there was no way it could possibly keep me as warm as the literature claimed. I was completely wrong. This jacket, which can be compressed to a very small size, will keep you warm at any temperature above zero. Highly recommended.

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

This jacket insulates well and is comfortable to run in. I like that all the pockets zip and the pocket on the chest is convenient. I'd recommend but not if you're on a budget as it's a little overpriced in my opinion.

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.

Fits well, as advertised with warmth. One odd design note that's kinda frustrating is the lack of a hook or loop to hang on a coat rack, the thermalrunner vest also lacks this. My gf and I have 6+ other running jackets on our coat rack we can just grab and go with but this requires a closet and hanger or for it to be packed down for storage. Since its already so lightweight I feel the loop/hook would make this more accessible.

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.

I bought this jacket to run in the Iowa winters. It’s early into the season, I have ran a handful of runs in -0 or below feels like and regular air temp. The most I have worn under this jacket is a light long sleeve and I have yet to get cold in my 3 mile runs.

Still have no idea how they made this jacket so light, breathable, packable and so incredibly warm. Jacket is almost too warm to wear in most scenarios depending on your region. Because it’s so packable it’s easy to wear when beginning your run and I usually take it off after warming up. Two weeks ago I ran in single digits with just a short sleeve shirt underneath and stayed at a perfect temperature.

Great feel, amazing look, nice and warm, awesome for layering. Love it

I wish it had a little more reflection built in and maybe a keychain holder in pocket. Otherwise love it

My friends love it!

This was my investment in years for winter adventuring here in chilly Upstate NY. This jacket is warm in all the right places, but is lightweight and uber-comfortable. I can wear it with just a tech tee underneath for trail runs when the temp is in the low 20s. Stellar wind-stoppage too. You will be happy with this one!

Fantastic product as youd expect from Janji

Great!! Warmest 100%
