I love this lens wrap! It isn't super thick, just the thickness of the cloth, no foam, but it wraps around my camera and lenses nicely and, most importantly, stays there. We live in South Florida where the morning humidity is near 100% RH. If I go out with a cold camera, the lens, body and internals fog up and are subjected to condensation. With this wrap, I leave the camera sit outside and warm up before unwrapping it and exposing it to the humidity. Doing this means no fog or condensation on the camera or lens! Would work great for telescopes too.
