I love this pak!

I carried 4, 1 gal. distilled water bottles from the grocery store, on my e-bike, with this pak. It was very heavy, but the pak didn't even break a sweat. I was comfy with it on my back. Not sure what it's like to walk with that kind of weight on it. I've only used it the one time so far. It seems to be very well made. I just love it. Thanks all ! C.
