Changing kit bag
Great product, used it many time to get rolls of film into developing tank.

Still got it
This is a really sturdy changing bag. The double closure avoids light leaks, as does the slightly fierce elasticated armhole arrangement. It's big enough to get a reasonable-sized daylight tank inside with plenty of room to work. The fabric is thick and it generally inspires confidence. Paterson remain the go-to brand for bits like this.

Great kit, it has worked a treat.
Great product, it's huge and gives room to work. Getting used to fumbling around in the dark bag for the scissors this size can be the only problem you'd have.

Not a “double zipper”
It’s a nice, large changing bag with plenty of room for rummaging, ideal for desktop use. It has a doubled ended zip (puller at each end), it doesn’t have a “double zipper” with the “added safety” that a double zip might provide. I had a small Paterson bag many, many years ago which packed down nice and small and served me well - this one is much bulkier, not suitable for carrying around in a camera bag. Arguably, a double ended zip could result in a light leak. I’ve reduced a star as it’s not quite as described. I’ll keep one puller tight against the end of the zip.

Does what it’s supposed to...and does it well
Being new to film developing this ag gas proved perfect. It keeps light out and is roomy enough to have the various bits of equipment to hand.

Wrist holes are a bit tight but maybe I have fat wrists.

A bit more expensive than some alternatives, but it's well built and so far had no issues with it.

Pretty much the standard, default changing bag. No one using film cameras should be without one. Even if you never develop film, should the need arise to remove snarled or damaged film from a camera this beats hiding under a blanket in a closet. I've used these for years. I develop my own film in the kitchen with Patterson processing tanks that let you do the process in room light. But you still need a dark place to load the film into the tanks for processing and these changing bags work perfectly. I've been using these since the 70's. They get the job done and are large enough to handle medium to large format tanks if needed.

Funziona benissimo. Ho sviluppato due rulli bw e non ho avuto problemi. Molto spaziosa.
