I weigh 170lbs and am 5' 11" tall with a 32 waist and 31 inseam.I ordered two pair. One large and one medium. As soon as I received them I threw them in the washing machine, warm water wash. Then I dried them in the dryer under medium heat. They take a while to dry, I guess its the wool in them but I had to run them twice to get them dry. I used the washer and dryer because where I'm going with them I will not have the option of line drying. After trying on both pair the medium fit perfect, the large I can wear but they are about 2-3 inches too long and just a little baggy. Especially hanging under the crotch area. But not so bad I could not wear them as a base layer. The waist band fit well around my waist on both pair.They are definitely thicker than the normal Fruit Of The Loom waffle type 100% cotton long johns. The kind you pick up at Walmart. They are very soft, I don't smell anything before or after washing.Haven't worn them in cold weather yet but I've no doubt that they will be warmer than the cheapo's and I'm satisfied with the purchase although I may get another pair of the medium.I gave them 4 stars only because I haven't yet tried them in cold weather and I cannot remark on longevity.May update this post later.

These are the best underlayment I have ever purchased. The wool is what makes them so great. I highly reccomend especially if you work outside (35 degrees or less)

This winter season, I've tried out about 3-4 different long john brands, and by far these made by the Indera/Coldpruf company have been the best for price/value. I'm about 6'1 with a 33 waist, slightly athletic, and for some reason most long john have good length but poor hip/waist measurement. For these, the length was a little big, but the waist size was almost perfect. And given the quality of materials, the price for me( about $35) was a STEAL. Try to find ANY long johns with a decent quality wool blend for less than $50, it's not happening. I can highly recommend these for -10-0 degree Celsius weather.

Here is a review from my boyfriend, the owner of the product:My girlfriend had a pair of these for many years and then handed them down to me. I wore them for years and like them so much I ordered a second pair of my own. I ride my bike to work and spend tons of time outdoors in All Seasons. They are incredibly warm and durable. They last forever through excessive washing and drying. Highly recommended!

Ye, these are more akin to the traditional 'long john' base layer in their styling/structure, which is exactly what I'm looking for: performance not fashion. This 50% cotton, 40% wool, 10% nylon blend is built for people who have to be outside in cold and inclement conditions, day in and day out. I wash them inside out in hot water and dry hot; their shrinkage is minimal, as is the pilling effect of the fabric. I have been wearing these now for two years, first in freezing Minnesota and now in the cold and damp of maritime Washington state; and I can't recommend them enough. Reasonable price, high efficiency and easy care. Who could ask for more?

I wanted something like the old duo-fold underwear that I loved. The new duo-fold is not the same as the old stuff. I don't like the feel of the various types of polyester underwear. If you want the comfort of cotton and warmth of wool, this is your underwear. I use it for ice fishing. Works great.
