Review: Nice comfortable product - Perfect fit. Husband is 5'6" 145lbs wearing Small. Soft feel yet light and warm.
Review: Warm, and Good for Layering, and Great for Cold Rides! - I picked up the medium black 250 and it’s been perfect for cold weather riding and chilly workdays. I’m 5'10" and 180 lbs, and while the fit is a bit loose, the length is perfect. After 2 years of regular use, it’s still going strong—just a minor hole at the ankle, easily hidden by socks. Pros: ✅ Great Cold-Weather Warmth (250 Weight) – Warm enough that I haven’t needed to upgrade to 320 ✅ Ideal for Motorcycle Rides & Cold Work Days – Keeps me warm without bulk ✅ Socks Are High Quality – Cozy and well-made ✅ Durable Over Time – Still in good shape after 2 years Cons: ❌ Slightly Loose Fit (Medium on 5'10", 180 lbs) – Not overly baggy, just not snug ❌ Minor Wear – Small hole near ankle, but nothing major Final Thoughts: Whether you’re riding in the cold or braving freezing temps at work, this base layer does the job exceptionally well. Warm, breathable, and built to last—an excellent investment for cold-weather comfort.

### ⭐⭐⭐⭐⭐ Best long johns I've ever owned !
*by R***. on October 14, 2025*

The Merino Wool Base Layer Mens Bottom Pants are very warm, soft and comfy. I bought the Heavyweight, 320g bottoms, and I was worried about them being too thick, they're not that thick at all, they are perfect, very, very comfortable and warm. I was golfing with them in 40 degree weather with 12 mph wind and my legs were not cold at all, plus they were not too warm either, actually just right. I didn't where anything but a t-shirt, polo shirt, and light wind proof Foot Joy golf jacket on top, but my chest and arms were not as comfy warm, as my legs were, even though I was wearing thin golf pants over the Merino bottoms. I live in a cold, northern, climate and have bought many, many, different types of "long Johns" and these are by far the best I've ever bought. When it comes to bottom layer long johns, I think they should be snug, but not too tight, I have a 33 inch waist and a 32 inch inseam and their medium size fit me perfect!
