Lightest weight baselayer pants?

I have some silk leggings in the 2oz range which are surprisingly warm *for their weight*. I highlight that portion only to say that they offer very little warmth, but I don’t expect anything weighing 2oz to have much insulating effect.

I agree with Ryan — even in a women’s M, anything lighter than 4-6 oz is of dubious value.  My favourite are my Polartec Powerstretch leggings (warm! soft!), but they’re about 6 oz.

Well, I decided to go ahead and pick up the Patagonia Cap 1’s today at the store.  I was pleasantly surprised at the weight–a men’s small weighs only 3.14 oz!  Did they redesign these?  I like the fit of the Cap 1’s better than the Underarmour stuff, since it’s not so tight.  The fabric feels nice too.  I’m hoping this will become my go-to layer for summer backpacking in the mountains down to the 30s/40s.  For stuff around freezing and below, I’ll probably go with my Smartwool microweight bottoms (just over 5 oz).

Yes they redesigned the fabric recently, much better. I don’t think those will provide all that much warmth but they will give you something clean to change into at night.

I’m bringing this back to life.   I’m looking for the lightest base layer set for having something clean to sleep in.

What are your suggestions.  The Patagonia Capilene LW’s are looking good.  What else is out there?

Men’s Copperfield wind pants at 1.35 oz from Enlightened E.

Haven’t used it yet – but, like you I just wanted something clean to sleep in for the night. This seems to be the lightest.

On this topic does anyone know of a bottom made from the 85g/m Polartec Alpha Direct?

I recently got a MacPac Nitro pullover and an now looking for a similarly simple set of bottoms from the same material. Would seem to fit the bill for OP as well if such an animal exists.

thanks!

These from Costco are an excellent value as a not very warm but great base layer leggings for sleeping in. I use them under shorts for running/hiking in rainy/chilly weather in the 30s and low 40s.

They also carry long and short sleeve shirts in the same material.

Can’t go wrong for under $15 for a two-pack.
