For the price these are very decent biking / hiking/ winter outdoor pants. I really looked at the reviews and the sizing closely hoping to find the right size. Ordered 3XL for 5 foot 10 205 athletic build. I was looking for a little room not something that look like tights and these fit fine plenty of room for base layer slightly long but I prefer that.
Have used on two different hikes with my dogs no biking yet and at 45 degrees they seemed a little warm at 35 degrees they seem to work quite well without a base layer.
Have not use them in snow or rain to see how they repel moisture and actually use so I'm interested in that may use them to ski and the next week or so will try to update after that.
I like these pants did get a little bit of sag through the back but stop noticing this halfway through the second hike. One thing that might be a drawback is the pockets feel like very flimsy light windbreaker material not sure how they will hold up. I would also be okay with a small back pocket on these
Overall for the price I am pleased with these and feel like they will be a decent pant for you in cold weather for biking hiking and outdoor activities

Read the other reviews regarding fit / size. I'm about 5'10" 175 lbs (177 cm, 80 kg), 33 or 34 inch (84 cm) waist, 30 inch (76 cm) inseam. I bought XL and the waist and length are perfect. I've wore these around the house for an hour, and I've one 30 mile ride, and two 10 mile work commute rides in them on subfreezing 30 F (-2 C) windy weather days. These aren't form fitting spandex type bike pants, nor are they loose sweat or warm up pants. There's a sort of quilted insulated lining - just enough to add warmth, but not so much that you'll be sweating on frosty days. They're a loose enough that I could wear running tights or long underwear underneath if I was going to be out in 0F (-18C) weather. There are zip slash pockets, which comfortably held some currency, ID and debit cards. The zip openings at the legs are gusseted, but open sufficiently to go over boots, or a probably to put them on or take them off without removing bike shoes (I wouldn't, You could, but why?). There is some difference between the fabric on the front and the fabric on the back, making the front a little more wind resistant than the back, but not visibly so. I expect I'll be buying a second pair of these - not for biking, but for windy chilly days when I'm working on the beach. They're good for biking, probably for xc skiing. They'd probably not be good for sitting in a stadium or on a ski lift. I wish they had some reflective material or accent near the knees for bike commuting, but I'm sure that would add to the dork factor that middle age men already have on bikes - and might not appeal to the rest of the consumers.

I read the other customer reviews carefully before purchasing these pants, which I intended to use for winter hiking in the Catskill Mountains of New York. While the pants were designed for hiking, many of the reviewers noted that they were excellent for many outdoor activities in the winter, including hiking. They were absolutely correct. These are the best wintertime hiking pants that I have ever purchased. They are remarkably comfortable. I used them three days ago on a 6.6-mile hike in 15-degree weather, gaining approximately 2,000 feet of elevation. They kept me warm and dry, and they flexed in a way that kept me comfortable throughout an arduous, icy hike.

Those who enjoy hiking in the winter should definitely purchase these pants.

These fit GREAT!! I'm 5'9" about 190lbs the XL perfect! Just enough room for base layers and plenty of mobility!
The length is perfect!
Time will tell how well they gold up but I'm pretty impressed so far!
They look great and are extremely comfortable!
I'll be buying another pair if these hold up!!

I ordered the 3XL ones the first time around and they were a little big on me (I'm 6' 190lbs). I returned them because the pockets were so poorly sewn that one was just a hole... however they immediately refunded me and I liked the feel enough that I thought I would try again. I ordered the size smaller 2XL, came in much better. Sewing was quality done, and to answer the waterproof/resistant question I added a photo, as you can see, repels water extremely well.
