I get these light weight, convertible, and very durable pants at Big 5 when they are on sale. I don't find them on the Internet.
They are extremely durable, thin fabric which blocks most lighter wind. Worn over a capilene or other long john they are warm enough for 32 F or somewhat below depending on whether I am walking or exercising, humidity and wind.
They are not waterproof but they hang well so in a mist or light precip they do ok.
Weigh 9 - 10 oz. on my scale w/o belt. Will work w/o belt, but I don't do it since the belt I made is also my emergency splint tightener, pack shoulder strap, and general cinch when I need one.
I use them as an outter layer, until I find something better.
Only cost $15 or so when on sale, so it may be a long time before something better shows up in my gear list.
The zippers in the legs are easy to use, easy to set up to reattach, and sturdy. The leggings roll up tight, small and are easy to stuff in a pack pocket or the pants pocket.
Two front of the legs pockets, one zips, one velcros which I like.
Two deep side hand pockets with mesh in one side to let dirt, water, whatever slip through. For whatever that function is worth, the mesh got a hole in it where my knife on a lanyard attached to my belt weighed on the bottom of the pocket -- so I am not sure of the value of the mesh pocket bottoms is.
No zipper in the bottom for boots on and off ease, but that isn't a real big problem, could slit them and attach velcro or have a zipper put in.
One hip pocket, velcro closure.
I take these, and their predecessors, with me everywhere ... packing, hiking, and on business trips. So: durable, light, usable, functional, always on me or in the pack = 5.
