U.S. Military M65 Trouser Liner

rated 5 of 5 stars I used these in the late Cold War Army—wonderful when worn alone but sometimes not warm when buttoned in the cold-weather fatigue pants. It's the same construction as the wonderful poncho liners which thankfully the U.S. military still provides. In addition to Amazon, etc, you can get these at Army-Navy surplus stores, although Amazon etc tends to be cheaper. Just concurring with other reviewers—it's a great piece of military surplus that is cheap, warm, and dries fast, although when buttoned… Full review

U.S. Military M65 Trouser Liner

rated 5 of 5 stars The M65 pant liner is a sub-$10 hidden gem for cold weather camping or backpacking. The key is using them as an overpant as they're sized large enough and easily unbutton to quickly don or doff without having to remove boots or existing layers. Perfect for those static situations like sitting around at camp or belaying or glassing while hunting. Would be way too warm for active use unless well below 0° IMO while wearing a base layer and hiking pant/shell.   The m65 pant liner was designed to be… Full review

Duluth Fleece-Lined Dry on the Fly Cargo Pants

rated 4.5 of 5 stars Duluth Trading "Dry-on-the-Fly" fleece lined nylon pants for $89.50. They have many nice features that make them a great bargain at their price. I recently got a pair of Duluth Trading nylon twill shell, fleece lined winter pants. For $89.50 they have great quality and easily beat out RailRiders $130 nylon shell, fleece lined nylon pants, even if they were the same price! Features: 100% nylon twill shell, very tightly woven polyester fleece lining (about 100 weight fleece) large crotch gusset for… Full review

Eddie Bauer Men's First Ascent Igniter Pants

rated 5 of 5 stars Love the pants. I purchased a pair of these pants last August. I use the pants for undergarments in scuba diving. Why? Because they use Primaloft as their insulation. If you believe the makers of Primaloft, it is as warm as down and maintains its insulator properties when wet. This is extremely import in scuba diving where heat transmission is 24 times greater in water than air, so if your suit floods this is critical. Why not just buy scuba undergarments? Because no scuba company makes a product… Full review

Patagonia Nano Puff Pants

rated 4 of 5 stars Warm and comfortable in action or at rest, these pants bring the insulation and packability expected from the Nano Puff line. A well-tailored fit and the ability to breathe well allows for active use in lower temps yet the puffy synthetic insulation protects against wind and cold even at rest. These pants would be a great addition for anyone looking for packable insulation for the lower half. Peakbaggers or thru hikers wanting easy to carry wind pants with insulation or fishermen wanting insulation… Full review

Mountain Hardwear Compressor Pant

rated 3.5 of 5 stars Great winter coverover pants. Easy to put on/off. Would recommend to others. I purchased the Mt Hardwear Compressor Pants as overpants for use while climbing in Alaska. They performed well and would recommend them to others. I have since used them on multi-day backcounty ski trips where the temps were dipping below 0 at night. These pants have full length zips so it is easy to put them on and take off. They are insulated so the added warmth is great on cold night. No need to take off your climbing… Full review

Marmot Ridgewood Insulated Pant

rated 5 of 5 stars Nice. These seem to have been eliminated from the lineup, so get a pair while you can. Very good for winter hiking if the snow isn't too deep as they get good air ventilation from the open cuffs to keep legs from getting sweaty. Very soft finish and comfortable. Not too hot with temps at 50-60° either. Full review

Eddie Bauer Men's First Ascent Igniter Pants

rated 5 of 5 stars Warm, easy to ventilate pants. They are made of synthetic insulation and will keep you warm even if you sweat. Full zippers make it easy to vent and put on gear even after the pants are on. Fit is true to size, these are comfortable pants with adjustable waist and a full zipper.  The full zipper allows you to ventilate easily if you get too hot. The zippers can also work from either end, which allows you to zip down from the waist, or up away from your boot to change footwear, add a harness easily,… Full review
