The Swarovski 49624 Stay-On-Case is specially made to protect a Swarovski STS and ATS-80 angled and straight spotting scope. It hugs the scope so that it is optimally embedded in the case. The case will not rub or slip inside the cover. The scope is perfectly protected from any nudges or jolts when traveling and in the thick of field action. It is supplied with a neoprene carrying strap.
