New Rain Cover...
The new and improved RC110 replaces the RC100. The fabric has a waterproof coating and the new design is free of any points for leakage caused by sewing through the fabric. It still has a hassle free tie down system which enables you to easily and quickly adjust the cover to fit your lens and camera during rainy or snowy weather.
It's comfortable to work under and will help to keep your own head dry in wet nasty weather. Better yet, the RC110 is very lightweight and can fold up into it's own tiny stuff sack, which makes it an ideal choice to have in your traveling gear case.
Intended for use with your 300mm to 600mm lenses.
