Personally I'd skip those. They look way more rough, almost "ridged" material, vs smooth nylon.I think the shine is more from the flash than the material.There are LOTS of different types of nylon. Rip stop vs non-ripstop, calendered (smoothed) vs non, various thread count/denier/density of fibers, waterproof vs water resistant, etc. These can affect the material's thickness, stickness, smoothness, etc.
