Shoulder strap pocket?

Some other cottage industry companies carry similar items such as MLD, Zimmerbuilt & Zpacks. If price isn't an option, these are proven true or they wouldn't sell them.

However, if you like MYOG and are half way decent at it, it wouldn't be too hard. You could make a stuff sack out of your material of choice, with a zipper at the top or along the front of the stuff sack instead of a drawstring closure. Or you could even use the drawstring closure instead of a zipper.

The trickiest part is keeping the pocket in place on the strap. First, you want install a closure system that will go around the strap, such as a strip of velcro or small webbing with a snap. That will hold down the bounce factor. Then you want to keep it from sliding down your strap. If your pack uses a sternum strap, a 2nd strip of velcro or webbing parallel to the first (one above the sternum strap and one below when in use) could work. Or, you could do something similar to the above referenced sellers and have a clip that would attach to your strap.

I have one and its pretty cool- but it's BIG, and a little unwieldy. You might also want to look at ZPacks' shoulder strap pocket, or similar designs from MLD and Simblissity. That's my favorite, though it's pretty tight for my iPhone and GPS. Good luck and have fun!

I've attached a small stuff sack on the shoulder strap.

I use a small attaching carabiner connecting the D ring and closing cord on top.

On the bottom – I put a small button inside the sack and wrapped a cord around the button on the outside, then attaching it to the shoulder strap so the sack doesn't bounce around.

i put my normal camera case on the sternum strap. easy to reach, doesn't bounce unless i run, easy to remove and put away if it rains.

You guys are good! Lots of options. I was thonking about it last night, and maybe all I really need is an iphone case that clips onto my sternum strap. But….$80 for the Lifeproof case and another $30 for the belt strap??

That's more than my whole backpack cost!

I could put my phone in a ziploc, then put it inside some rubbery/placticky/leathery case with a belt loop stitched to the back. Loop that to my sternum strap and call it a day. Any iPhone specific cases that would do this well?

Other make similar bags (including Cascade Designs I think), but you get the idea. You should be able to attach this to any strip with two pieces of shock cord like a water bottle.
