G'day Mav,

They'll keep out rain like other side walls in the sense that they create a barrier, but gazebo walls in general don't come with a watehead rating.  This means they're not waterproof and there no guarantee of water protection.  If you have previously had Oztrail Gazebo walls, or other brands which as essentially similar to these & this gazebo style, they have the same performance.  

G'day Matthew, 

I've just checked with the info provided by Coleman, and the Deluxe Gazebo 4.5 x 3 Sunwall only comes in white.

G'day Adrian,

I've just checked for you, and the Coleman Deluxe Gazebo 4.5 x 3 Sunwall uses no-gap velcro. 

This sunwall is made to fit perfectly with the Deluxe Gazebo 4.5 x 3 size, so you shouldn't have any issues with fit if that's the model you have.
