Paterson PTP125 Overview
Having a changing bag means a jammed or partly exposed film roll can be safely removed from the camera, shooting can continue, and your film can be loaded into a developing tank without having to find a darkroom.
It has a fail-safe double skin with a double zip closure. The inner lining is specially designed to prevent perspiration during prolonged use.
The Paterson changing bag is small enough to fit in a camera bag, yet large enough to contain a fully-opened camera back or a roll of film that needs to be loaded into a tank.

Arm holes are sized for a baby

The bag seems high-quality however not even my wife can get her arms in to the bag comfortably and I am a big guy the only way I’m going to be able to use. This is to cut the elastic and maybe even pull apart the seam a little bit. These things should come with adjustable arm Sleeves.
Not for people with large hands and arms

This was a gift for someone who did not open until six months later when they used for first time. Their hands did not fit inside the bag. I can't return it now. The sales person said this is a must have product for someone who is shooting 4x5 sheet film. Now I stuck with this. Large on box can be misinterpreted. Maybe the cats will love sleeping on it. We continue to darken the kitchen at night when changing slide film.

Is this big enough for the Patterson 8-reel tank?
The Paterson Changing Bag (24.2 x 27.5") is large enough for the Paterson Super System 4 Multi-Reel 8 Developing Tank.
But you will need to leave it on its side.

Is the inside of the bag dust free?
Is the inside of the bag dust free?
It’s dust free when brand new and still in the packaging. Whether it remains dust free depends on whether the equipment placed inside is dust free and how it’s stored. I think a small amount of dust inside the bag is inevitable but shouldn’t cause any serious issues.
