I‘m building a huge igloo with my stepbrother and we are kneeling by this pile of snow we shoveled and we are hollowing it out, and our goal is to work 6 hours straight on this thing, but like halfway through we have to go in because we are cold because our pants are soaking from the knees down. I‘ve tried wearing 4 PAIRS OF PANTS!!! (3 denim jeans, 1 pair of mesh pajama pants) and still, dripping wet. Our last resort is to tape paper-towels to our knees, but when they get soaked, they‘ll shred up and fall apart and just make us colder. Any tips on how to keep your knees dry in extensive periods kneeling in the snow?
