Why did Amazon ask me to rate this on warmth, comfort, and thickness? Uhm....you know what, let's have fun with this.
It's a lovely, warm, dark grey fabric.
It feels really comfortable in the hand, not like it belongs there because it belongs on your belt, or your backpack strap or whatnot, but when I'm sliding my belt through it to get ready to carry my DSLR around at the ready..... goodness is it comfortable.
Whatever they put in the back to stiffen it up has a perfect thickness to stiffen it.
Ok that was fun but;
The Capture Clip is like, like what I've always been waiting for, but never knew I needed it until I got one. Of course mounting it to your belt, sideways, is freaking super annoying. Drawing your camera one handed, awful. Putting the camera back o your belt sideways, awful. Having a reasonably weighty camera attached to the Capture Clip on a backpack strap, not bad really.
Put the Pro Pad on there......that thick, warm, comfortable Pro Pad, well look out world. It does the following amazing things;
Drops your camera down a little lower off of your belt. Now I can actually wear a flannel or other shirt and easily access my camera. Nothing is cooler than an aging hipster who can draw his DSLR the fastest during a high noon landscape shoot.
Allows for real, easy, one handed access off of your hip. Now the quick release pin is right where my pinky wants to go. My eye says "wow, this could be a reat photo" and somehow my camera is just in my hands. Then when I'm done, it just slides straight down into the clip. Doing this all sideways is a stellar pain the tuckus.
Adds firmness with its 5 star thickness to any mounting situation. Like let's say you pop the Capture Clip onto the shoulder strap of your goofy old Domke J-bag because you want to relive your glory days of backpacking overseas. You try to tug your camera out of the clip and the clip wiggles a bit, flexes the strap and whatnot. Pro Pad + thickness + stiffness = comfort and warmth at 5 star levels.
tldr: if you're gonna hang your camera on your hip, get this. Gonna put it anywhere else, you might not need it.
