We took the Original Mountain pant and lined it with flannel for enhanced versatility. Triple-stitched seams, diamond-shaped action gusset, hidden side-seam deep drill hand pocket, reinforced pocket bags, and "mudflap" reinforced heel cuffs make this pant a go-to in cold weather.

To And From the Mountain...

Nothing beats back the cold and wind like these Flannel Mountain Pant. The material inside and out is durable and can tackle any rough play whether you're in town at a bar or out on the mountain making repairs to the fence line. The fit is true to size and so is the length so you can buy worry free and they break-in after only a single wash. In a word...perfect! You won't be disappointed.

These are my winter go to pants. I have a couple of pairs and wear them constantly when the weather is cold. I think they look good too!

Best wintertime pants

Comfort, warmth and great fit. This is my third MK lined pants, added to jeans and khakis. No more longjohns binding and knotting up etc.

Feels like PJs, function like OMPs

These pants are ridiculously comfortable. I honestly feel like I’m wearing Pajama Pants. The flannel lining is as nice as you could ask for and they have the same solid exterior as all OMPs do. These pants have been out in the woods several times, covered in snow, mud and blood and they wash right out. For hunting and winter activities these are a go to pant.

Very Rugged but fit smaller than expected

I wear a 32 at Gap, AE, Old Navy. Because these are lined I ordered a 34 but they are more snug than I was expecting. They fit like a snug 32 had I know I would have probably gone up to a 36. Other than that everyrhing else about them seems great
