Rated 4.3 out of 5 by 30 reviewers.
Rated 4 out of 5 by Thank goodness for Nonna (grandma) I ordered a large because I had a pair of Columbia fleece pants from a long time ago that were too small. Problem was, the size on the tag was with some obscure scale, like a number in the 200s, so I had no idea what size they were. My grandmother's educated guess was they were a medium so I ordered large. They ended up being much too big, but thankfully expert seamstress Nonna was able to cut the length and leg diameter down to size. Next time I know to buy medium :) December 15, 2016
Rated 5 out of 5 by Great quality pants. I got a pair a few weeks back and loved them so much I got another pair. The first pair was washed a bunch of time and there was no shrinkage compared to the second pair. Pants are super comfortable for wearing at home, to the gym or for running outside during cold, wet morning. October 28, 2016
Rated 5 out of 5 by Very Comfortable My husband lives in these pants. Comfy but stylish. This is our second time buying these pants. They wear well and wash well. They are also great to travel in. My husband is very tall but the leg length is quite generous. A great buy all around! October 5, 2016
Rated 5 out of 5 by Very comfortable. Very comfortable pants that are true to size. They are a relaxed fit so they are going to be a little baggy, but I wouldn't have it any other way. The pockets are a little shallow and the rear pocket has a zipper. Again, another top notch product from Columbia. December 2, 2015
Rated 5 out of 5 by This product is really cozy and comfortable. My husband and I really love wearing these fleece pants. They are perfect for around the house as well as casual wear. September 2, 2015
Rated 5 out of 5 by excellent very satisfied, excellent quality. February 28, 2015
Rated 5 out of 5 by Men's Trek Pant's The material is so soft and flexible. February 23, 2015
Rated 5 out of 5 by Excellent comfort... Loved this first pair of trek pants...comfort from the minute I put them on...stylish enough to wear to the grocery store. February 14, 2015
Rated 2 out of 5 by Pants are way too big and pockets are too small It's hard to believe that Columbia is actually selling such a misshapen piece of junk. I'm usually a big fan of Columbia gear, including its pants, but this stands out for its poor design and quality. The pants are gigantic -- a medium is swimming on me, a 5' 9", 177-pound guy. Yet as other reviewers have said, the pockets are so shallow as to be unusable, unable to safely hold a wallet or smartphone. And the material has a cheap feel. Shipping these back. Very disappointed. August 4, 2014
Rated 2 out of 5 by Not a Good Fit The material is to thick, the in-seem is to short, and the legs are a little to flared. April 2, 2014
Rated 5 out of 5 by Fast Trek Fleece Pants Nice soft fleece & great for lounging around the house. Ordered a medium & they fit nicely in the waist but about an inch to long. Took them to a tailor to have them hemmed, & all is well. March 8, 2014
Rated 5 out of 5 by Columbia Fast Trek pants Nice quality pants. Very warm for these cold winter days. Size is just right. My only complaint is that I wish the leg bottoms were more tapered and not as wide. Well worth the price. February 15, 2014
Rated 5 out of 5 by Columbia Fleece Nice fleece pants and they are warm without a lot of weight. The fleece is smooth and washes nicely. The cut is generous and the color even. Good for lounging or a trip to the gym. February 15, 2014
Rated 3 out of 5 by Great material/feel, awful pocket size These pants are incredibly comfortable and warm, but in my opinion have something of a fatal flaw. The pockets are much too shallow. I have already lost one expensive cell phone and had a couple other harrowing experiences tracking down items which fell out of these pockets when on the road. Perfect pants for wearing at home but very bad for anywhere else that you might want to go with items in your pockets. Would give them a 3.5 if I could... February 5, 2014
Rated 4 out of 5 by Drawcord could be better The drawcord does not pull easily for tightening or loosening the waist. Otherwise the fleece pants are great. January 15, 2014
Rated 4 out of 5 by House Pants I am 6'4" tall and the pants ran a little long, but they felt great. January 6, 2014
Rated 5 out of 5 by Bought it for a Christmas present It was a huge hit overall. The individual is a fan of Columbia products in general, but had specifically eyed this one out in a store. The only issue he had was his large phone (Note 3) kept falling out of the rather shallow side pockets. Other than that, the product was a perfect fit! December 31, 2013
Rated 5 out of 5 by Great for canoe-camping I found these looking for warm, quick-dry fleece pants for cool-weather canoeing and camping. Regular cotton fleece is warm, but not so good if it gets wet--"cotton kills". Cotton fleece tends to bag at the knees, too. These pants are light, super-comfortable, and keep their shape. Good value! October 21, 2013
Rated 3 out of 5 by Inseam The waist size on this product was perfect for me, but the inseam length was too long. Now I have to have them tailored. Overall, a good product if you're tall enough. September 8, 2013
Rated 5 out of 5 by Great Fit, Quality Product They fit great. Well made product. I will be wearing them under my foul weather gear fishing this fall and winter! July 21, 2013
Rated 4 out of 5 by Pure fleece pants Item is as described. Pure fleece pants. Not sure I would describe these as trek pants, more like Sunday morning lounging upscale PJ's. These were perfect after a day on the slopes. Easy care makes these better than your avg sweats. February 9, 2013
Rated 4 out of 5 by Men's Fast Track II Pants have had a design change These new pants are a different design than the original pants I had purchased. I needed the 2 zippers up the ankles so I could use them as warmup pants and remove the pants without taking off my tennis shoes. My new pants did not have these ankle zippers. February 8, 2013
Rated 5 out of 5 by super comfortable relaxed and comfortable, perfect for cold weather and walks to park November 25, 2012
Rated 4 out of 5 by pants length was longer than expected, had to get shortened. October 22, 2012
Rated 4 out of 5 by happy pants!! nothing better than fleece pants! so comfortable!! October 4, 2012
Rated 3 out of 5 by WAY too BIG Got them for B-day gift...but very much over sized for a large! September 19, 2012
Rated 5 out of 5 by Does the job The fleece really blows basic sweat pants out of the water. These are toasty. They do run a bit large and long though--but this is often a good thing. July 26, 2012
Rated 4 out of 5 by Great product Excellent product would recommend to everyone. June 24, 2012
Rated 5 out of 5 by Functional These were purchased for indoor warmth and comfort and perform both functions very well. January 2, 2012
Rated 5 out of 5 by Wardrobe Staple The winters in Oregon are cold, rainy, and very windy. These fleece pants are my main go-to item during the winter. They are extremely comfortable, fashionable, and keep my entire legs toasty. Columbia ROCKS! November 22, 2011
