Butler Creek Bikini Style Scope Cover

From MidwayUSA

Two pliable black rubber-like cups joined by stretch retainers create a tight moisture-proof and dust-proof seal to protect your valuable optics while in storage, transit or in the field. Bikini Style fits all standard scopes with outside bell diameters up to 62mm. A pair of stretchable bands secure covers to the ends of the scope and cover can be removed with a flick of the wrist.
