Review: Ninja, running around in long skivvies. - I was skeptical about ordering anything wool because of that...you know...the itch. But after trying Under Armour and reading and watching about wool products, I really was hopeful about merino wool. Fit and finish: Out of the box, these bad boys are good to go. When I tried them on, I walked around and thought, "ok, here comes the itch" (enter delayed reaction). Although I felt some itch, it's not as bad as I expected, but I got over it. Some people will be more/over/hyper-sensitive to merino wool, especially if it's going to be 100%. Other products they might try are a wool/nylon or wool/poly blend which might be more comfortable. For size, I normally wear a 34 waist and a 30 inseam pants. Minus33.com size chart says large...I guess I should've ordered large, but I ordered medium instead. The mediums fit just right. Now if you;re a dude who's got a lot of junk in your trunk -front/back or both- you might wanna go large... I wore these for a week with little activity, if you include shovelling snow in 25F weather, before washing; and there was no loss of warmth. It's not so warm that you feel cozy, but just right where your knees don't start chattering. At the end of my work shifts and before I went to bed, I'd change out of them. As far as wicking away moisture, the -33 did a better job at wicking away moisture and odor without losing warmth compared to the Under Armour cold gear. The UA Cold Gear will wick moisture but you will get cold. If I could give you a rough numerical estimate, I'd tell you, -33 will wick 20% more moisture than UA. -33 will retain 20% or more warmth than UA, especially with little/nil activity. For washing, I used liquid detergent in gentle cycle, but will opt for trying shampoo (wool=hair). Then hang dry. Overall, for more sensitive skin, try a wool/poly blend. For less sensitive skin, I highly recommend -minus 33 Minus 33 Kancamagus - little itch, good price, good fit, good finish, good quality. 12/24/2013: I'm wearing the set that I washed. I didn't notice any loss of fabric or fraying. It's 16F outside and I got poly cotton pants over the Minus 33. I'm good to go -not too cold, not shivering- just standing/pacing around smoking a Newport just after 2000 (8pm). I'm at work now, it's after 2300, it's 73F inside and I'm toasty and not roasty. Merry Christmas.
Review: Initial Review - Update to come by end of 2015 - ***This is my initial review after receiving the package and wearing the product. I bought this for hunting season in PA as well as skiing season here in NJ, and will be able to test it further and update this review by the end of the year. I bought this product because I am tired of looking and feeling like the Michelin Man during hunting season with my puffy down clothes and multiple layers. (Bought together with Yukon Men's Expedition Crew Top). I want this to be my base layer, and then simply wear my hunting pants over it. Skiing I've never had a problem wearing just underwear and ski pants and actually wind up sweating because of the movement and I am always warm in general. But something about sitting in one spot while hunting really lets the cold seep in. I won't be able to update this review with how well it performs until the end of 2015, but here are my initial thoughts: Packaging: The packaging is simple, compact, and came with no issues. Fit: I'm 5'5, 140 pounds and have a waist size of about 29/30 inches. I bought a small, and both these bottoms as well as the small Yukon top fit perfectly. Tight fitting (how I usually like my clothing, especially base layers), but extremely comfortable and hugs the body well. Warmth: I noticed as soon as I put these on, my entire body felt cooled down. This to me is a good thing, as it means instead of just trapping heat and moisture, the wool is allowing my body to breath while still retaining heat. To confirm this, I took everything off and felt the inside and they were very warm to the touch. Quality: The quality of the product is very good. The material feels good, looks good (good enough that you could actually wear the Yukon top in public with a nice pair of jeans and not feel strange about it). However these bottoms are not to be worn in public without a layer over them - unless you want people staring :) So far, I am very satisfied with this product. I will update when I can, and if it performs well I will be ordering more of the tops in different weights for the different seasons (even summer) because I really like the quality, fit, comfort, and breathability. I can only imagine seeing myself wearing these bottoms in winter, so I will stick with these and if they pass the winter test I would definitely order more.
