Doing Things Different — and Liking It

Colin,
Searched the web and found plenty of fishnet undies using the term, "mesh."
What I could not find were the mesh polo shirts I used to wear that were not just a loose weave, but real see- through mesh weave that was very elastic and too thick for the bugs to bite through. (All the polyester polos I have now are easily pierced by skeeters) It was also quite warm under a shell or sweater. Unfortunately, it was all or mostly cotton, and eventually rotted out and tore itself apart. Miss it.

Google for "fishnet long underwear". Most of the hits are for brief-and-sexy — perhaps not what you are looking for, but a few hits look good. Wiggy's, Fox Ridge (selling Wiggy's), Canadian Wintersports,

Wiggy's is nylon. Canadian WinterSports is polypropylene.

Helly Hansen sells their 'Odin' line of baselayers which is partially mesh. The long sleeve top has a mesh torso and then fabric sleeves. The pants are mesh in the thigh area. The sleeves are merino wool if I recall correctly (I used to work for HH) so the whole garment is pretty light. I think it's ~4-5oz for a medium but I could be wrong. It would be a very light top if you chopped it into a t-shirt and lopped off the turtle neck.

Aclima of Norway make 100% merino ('Woolnet') and polypro ('Coolnet') garments.
