It is like magic how it stays cool under the cover even though the scope is sitting in full sun. And, it's very light and easy to fold compactly. My only quibble is with the elastic drawstring, as it takes quite some time to get it cinched up. Perhaps a non-elastic cord would be better. All the same I am very happy to be able to protect my equipment with this.
Purchase was simple. Quality of scope cover is unsurpassed. Great buy! Will buy more.
