The Strata Merino Quarter Zip Thermal Top is constructed using Nuyarn® technology, a lightweight, incredibly comfortable, and durable blend of Merino wool and nylon. By removing the twist of the yarns and drafting the fibers over a nylon core, Nuyarn® has produced a fabric with higher stretch and recovery, better moisture management, greater warmth and increased durability than traditional Merinos. It culminates to an itch-free, moisture wicking, and naturally odor resistant material to take the edge off in cool conditions.

Love it

Perfect weight and warmth for me Also like how I can remove the hood.

Merino top with hood

It’s ok however too expensive for what it does and I had a problem with static sleeping in it all night long in my tent.

Best Outdoor Pyjamas I ever had

I bought the top and the pants - they are super comfortable for both - sleep and ride.
Compared to "normal merino", this nuyarn feels smoother for me - no itching whatsoever.
Will keep you dry and warm.
Also, they do not get smelly quickly.
There is a reason these thinds are almost sold out.
I need another set.

I Can't Quite Recommend Mosko Yet...

I really want to like Mosko Moto. I like what they are doing with highest quality gear. That being said I did purchase a pair of their Woodsman Enduro riding pants which were amazing build quality and I wanted to keep them however the inseam length was just way too long even with under gear and boots on (I'm 5'8" tall with a 30 inch inseam). If they offered these pants with that inseam option I would immediately purchase. After returning the pants I ordered the quarter zip long sleeve with removable hood. Everything is good EXCEPT the stitching at the quarter zip appears to have been sewn while under tension because the fabric is wavy on the chest while wearing. They don't disappear unless you pull the shirt taught which is a manufacture/quality control defect. At these products' price point they should be flawless. I did not realize the wavy until after I removed the tags and looked in the mirror. Keeping the shirt as it will spend most of it's time under a riding jacket.

Best ever!

I bought the Merino combo of pants and sweater last year and wear them several times a week. Whether on the motorcycle or on the sofa - they keep you super warm, and the quality is really great. I especially like the hood. I think I'll get another set in a different color to have a bit of variety.
