I live in the mountains of West Virginia and decided to take my KTM 890 Rally! It’s 42 degrees and there are patches of snow. This is the first chance I had to test out my new ecotherm jacket and I love it! I put it on over a t shirt and had it on high! I was riding at high speeds and still found myself starting to get hot! Mosko products are definitely worth every penny!

Have used 3 days straight in temps rangeing from 40 to mid 50s. 50 and above without heat.
And below 50 with heat made riding enjoyable.
It's also lighter and more packable than the heavy fleece I usually wear. Expensive for sure. But so far I'm very happy with it.
It's made me realize I need heated grips on my 890!
And maybe 🤔 a heated seat. LoL

I've been riding 40 years and have tried all the Gerbing, Venture heat stuff. This jacket continues to impress me after two years of use in remote places. Nothing prepared me for how good this heated puffy was going to be (and I commute in NYC to film sets down to 18 degrees in the winter - F*** the subways).

I got my Ectotherm December of 21. I used it on my dual sport in the Chihuahua desert of west Texas, all over Arizona, Utah, Death Valley, Redwood Forests of Northern California. I then used it on my sport touring bike from southern Arizona up to Utah and the Grand Canyon, trying to outrun a snow storm coming south through Flagstaff and Sedona (I almost won). Out west there are often huge variations in temperature from time of day and elevation changes and this jacket makes planning for those rides in shoulder seasons possible.

I recently used it again for a long tour from Arizona down to Baja this year. It was the only puffy jacket I took with me as you need to pack minimally for a long journey across so climate zones while doing off-road. Sometimes I would turn it on max in the mountain passes and other times I can leave it off, only as a base layer. Baja Norte can still be chilly in the winter time but Baja Sur can get into the 80's during the day and warmer when working on the bike off-road. Either way, it was a perfect base layer to explore towns in, walking around with the cord tucked away. It's as good as a Patagonia puffy when off the bike. I spent many nights around a campfire on a beach or in the desert of Catavina, under a blanket of stars, and was super cozy in my Ectotherm. Now I just need to add the Strata base layers so I can have zip off long johns and maximum flexibility for morning to mid-day temperature changes!

I'm back in NYC now and it's plugged into my bike and under my Klim Latitude jacket as I commute each day. I have to admit, every time I put it on, I long to be on another adventure instead of fighting traffic on busy city streets...

I ordered a large since Mosko say that they have fixed the fitment issues and this is mostly true. It fits greats everywhere except for the hips and butt area. I also tried the XL but it's too big in the arms. It bunches and is loose in the body and a little long. The problem with the large is that its pretty snug at its lowest point and I have slightly wide hips and a butt and it just doesn't look good from behind. I'm not excessively overweight. A dadbod and I could lose 10lbs and it's snug enough that it visibly looks a little meh in the area. Functionally, there is zero impact but I enjoy it when my clothes compliment me, like almost everyone else. Not sure why sizing is an ongoing issue with Mosko. Is everyone at the office shaped the same? Narrow hips and no butt? I have a Jackaloft that is an XL and fits right (a little long in the sleeves), but...
I dont really wear XL in anything. I'm universally a large and these items fit correctly.

Now why is it that Mosko doesnt fit? Is it a me issue or is it Mosko? Sure, a lot of people wont nitpick but for the price, I want this to be more than motorcycle apparel. It's warm, comfy and doesnt look like a MC clothing. From the front its very flattering but as soon as I turn around...well you decide if its an issue for you or not.

Anyways, verdict is that its a good jacket, hence the 4 stars and if you are built differently, buy it! Only having to run one mid layer under a shell is a game changer. The color is fantastic (unlike the luminous colors they currently have for the Rak and Basilisk) and it looks good.
