Plans were to use backpac for infield hunting bag. Medical issues changed that. Ending up on a knee scooter, the backpac went into service to haul everything I could throw at it(or in it) for nine months of hard labor.
Once this little jewel cmae off the knee scooter handle bars, it went straight to the woods to carry ammo, clothing, food and electronics (deer stand entertainment).
No problems, great buy.
Actually bought two of them as I figured I would need a back-up when one crapped out at the wrong time. Over a year and still on my first one.
