The Strata Merino Zip-off Thermal Bottom is the long john you never knew you needed. It brings a new era of innovation to your ADV layering kit.Full-length separating side zips allow you to easily de-layer without removing your boots or pants. No more sacrificing comfort for convenience. No more dancing out of your pants when things heat up. Just drop your trousers and unzip the base layer to remove them trailside. So quick and easy you might even be able to get them off (or on) before your buddies catch up.

[FYI, we will not be restocking the Strata Thermal Bottom in Umber.]

DESIGN

Temperatures can swing wildly on any adventure. Cold mornings turn into hot days on trail. And hot days turn quickly into cold nights when the sun ducks out of sight. Adding or removing a layer in these situations is a no-brainer, but who wants to stop the ride to pull off your boots, dance out of your pants, and adjust your layers. All too often we sacrifice comfort to avoid these tedious moments. The Strata Merino Zip-off Thermal Bottom’s full-length leg zippers, over armor fit, and above the boot design allow you to quickly and easily shed or add layers without removing your boots and outer pant. 

The Strata Merino Zip-off Thermal Bottom 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.

These are nice and comfortable. The cinch straps on both sides come in handy. I’ll know one star off for the price which seems high but always solid product from Mosko.

No Boundary

After many, many years with the Basilik jacket (V1) I decided to pick up the Boundary jacket for the built-in armor. It’s a serious investment but my experience with all the Mosko gear is that it lasts forever, so on a dollar per ride basis, it’s an excellent value. High quality throughout and the XL sizing was on point for me. Just like the Basilik, the Boundary works when it’s both chilly and warm - good venting options. My only quibbles to date are the lack of an inside pocket a la the Basilik and a very stiff collar that at times interferes with my helmet - though some of this is due to it being new. All in all, this is a riding jacket that will last a lifetime!

How to keep your wrinkle berries happy.

These base underwear are excellent for Texas winter days when it's 30's in the morning and high 60's by early noon. You no ok longer have to deal with hot legs and wrinkle berries due to pants and gear being in the way.
