They are lightweight, but they aren't super-thin. They are made of a material with a smooth stretchy DWR finished material with a soft brushed lining. They are quite tear resistant, in my experience, and I wore them from pre-season scouting to late November snows.
Travis,
I agree completely that 10 months is way too long, and the communication should have been better. Just keep in mind that Kuiu may have not been lying to you, they could have been making good faith estimates, based on the information they were getting from the supplier/shipper.
I only say this from experience many years ago working in a flyfishing retail store, and suppliers were constantly dragging us along, and incorrect information would filter through us to customers and we ended up looking the dope.
I hope Kuiu gets their supply issues worked out ASAP, as the products I have are really top notch. I have ordered some of their stuff lately, but only if it was in stock and ready to ship. Shipping has been really fast for me. I got the gaiters last week, and I like the design a lot.
