Pros
- Dirt cheap
- Warm
- Lightweight
- Easy to find
- Durable
Cons
- Requires some mods
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 buttoned into the m65 pant so they don't exactly have a good waist closure system, just a button with 2 slots of adjustment. I'm going to mod mine with some 550 cord.
Regardless, 10ozs, very warm, lots of room to layer under and I paid around $10 shipped for an unused pair.
Cool added bonus is that since the sides have 5" gaps between the buttons, you can access your pockets without having to remove or unbutton the pants. Also the crotch is open for quick and easy access. Even with the gaps, the pants still add a ton of warmth.
Be sure to order the long version as the pant liners are cut short to not interfere with tall combat boots. Even with the long they will be a bit short but still work.
Pics below are me wearing a size large long (18 degrees F, very comfortable). I'm 6'2" 190lbs with a 36" inseam for context.

Nice! As I asked in your other review, where do I find these?

The jacket liners, aka smoking jackets, are also warm and lightweight. They don't compact very well for their size, though.

I've got a pair of these that are almost 40 years old now. Mine were issued. And if you don't mind the weight of some of this gear, you'd be hard pressed to find warmer clothing. I've got a pair of the arctic mittens, the bunny boots, and muk-luks. Anyone who's ever worn a filed jacket with the liner can testify just how warm they can be when you're properly layered underneath. Love these pants for sittin' around the fire or just hangin' around camp. But JtothaK is right about needing sub-0 temps to be active wearing these.

Goose - purchased unused (NOS) from ebay. To Phil's point, I have an ultralight hooded Mont Bell synthetic mid layer (and a Montane) that packs much smaller than the m65 jacket liner (smoking jacket). Of course, the Mont Bell jacket was around $150. And this is the point of my reviews, there are some really good deals out there from the mil surplus side that actually perform quite well when compared to commercial offerings. We all know that the, for example, Patagonia Micropuff is great and we all know that Western Mountaineering bags are incredible (love my Summerlite) but there don't seem to be many reviews around the mil spec side within the context of outdoor, non-military, use.

Have some military Thermolite Micro insulated synthetic liner pants and love them but the M65 pants ae a LOT less money. Thanks for the idea. I'll post it on WINTER TREKKING. Eric B.

They really work best as a liner as that is what they were designed to be. They button into the M51 field pants which are now made of ripstop synthetic. I use the liner and new M51 field pants every winter.

@Bill - The application of using the liner as an overpant is more in-line with the modern PCU/ECWCS level 7 design of wearing a really warm insulated pant OVER the other layers. The benefits are not overheating when under exertion, drying the other layers via body heat and the ability to quickly don and doff.

Phil, synthetic fiber quilted jacket liners compress (stuff) far better than the same size and shape fleece liners. Only down liners would compress better. That's why I have a light down jacket and liner pants and a +30 F. and -20 F. down sleeping bags. Oh yeah,and down is lighter than synthetic too, R value being equal.

If you can find a set of the older style camouflage overwhites in nylon they also button into those. Putting a wind resistant layer over these really does increase the insulation but naturally at the expense of some added weight. The big advantage of the nylon overwhite is a long knee length side zipper so you don't need to take of your boots to put them on. You can dye the overpants any bright colour you like too. As already noted the only real downside to these is the weight.

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.
Pros
- Super lightweight
- Keeps you warm
- Dries fast
Cons
- Sweating in them can make them cold
Just concurring with other reviewers—it's a great piece of military surplus that is cheap, warm, and dries fast, although when buttoned into the Army cold-weather fatigue pants while on patrol in subfreezing weather on the Korean DMZ or in Germany, if you sweated in them, you got pretty cold. But those were always forced situations and not the same as much more leisurely backpacking or winter sports, or even search and rescue. They're a good bargain and work well as described.
The problem with buying any kind of military surplus online is you don't know what you'll get and it's such a hassle to send back. It's always best to go in person to a military surplus store so you can touch, examine, and pick out what you want. Most surplus stores carry the M65 liners.
If you have to go online, then still go to a military surplus store. One of the best is Old Grouch's. They have the liner for $3! (oldgrouch dot com)

I got the best results by wearing these under my BDU or Gore-Tex pants, over the polypro longjohns. Of course, I was an artilleryman, not an infantryman, but the glow plug for the cab heater in my track always seemed to break when it got cold and it is COLD inside a metal box in the German winter. I tended to wear the field pants over the top of everything because they were tougher than the Gore-Tex pants.
