Low cost Puffy Pants

western mountaineering flash pants are pretty amazing. About $175 a pair but you can (rarely) find them on sale for less than 150…

incredibly warm, about 7 oz… on some things, it's just worth it to spend the extra dough. when it is on things that keep me from going hypothermic…

I second the Patagona Puff pants, they can be had on ebay for less than 80bucks.

Light insulated pants under $100? We can all dream….

The Montbell's are the least expensive and lightest ones, plus being a big company, they can often be found on sale.

If you have time, you might be able to find them on sale for close to $100. Or used for less.

Otherwise, some very basic fleece pants, with out zippers, and pocktes etc, are warm and cheap, but obviously not as light.

Your choice.

…but definitely durable and in the price range are the military surplus M65 Pant Liners. They’re about 9.5 oz, according to this thread, and are made of the same stuff as a poncho liner (which is good down into the mid-forties for most folks when sleeping).

Hope it helps!

Those surplus, military liner pants are cut to fit about mid-calf, above high top military boots. Buy a second pair of liner pants to cut to add more length to the pant legs, hand stitched, no sewing machine necessary.

With a sewing machine, you could make them into chaps to save some weight.

If you can find them, the 'long' version comes to aboute ankle length.

I don't wear puffy pants often, but when i do, these dirt bagger specials work well.

If I had more ambition, I'd upgrade my basic sewing skills and sew in some cords on the ankles and waist.

And, as someone mentioned, these pants are only $10. :)

I just received my M65 pant liners today.
I got the small (27-31) waist – long inseam size and side buttons version. It weighs 390g or 14 oz – quite a bit more than I expected. The version without side buttons weighs less I imagine, but I wanted this version so I can layer over my pants when resting/setting up camp/cooking.

I'm 29-30" in waist, 31" inseam, and skinny. The pant liner comes down to my ankles, I can't complain. The waist has some adjustment to it, can't complain here either. The pant liner is very baggy on the other hand, I don't see how it could be called a pant liner (unless you're a rapper :)). As an overpant it is adequate, but still on the baggy side.

If I were a 32" waist, I wouldn't shy away from the SM size. If I ever come across a pair, I'd like to try an XS size…

Yeah, the ones w/o the side buttons are about 3-4 oz lighter.

Find I use them more for car camping or just before a backpacking trip when I bivvied the night before. (In the morning, I slip them over shorts as I am packing up my gear and eating breakfast)

Some of the cheaper snowmachine pants are acceptably light, though I'd go with the military ones if you aren't mountaineering.

The military green Patagonia puff trousers are very good, my Xl comes in at 470g
