KLIM Nac Pak Technical Backpack - Waterproof Hiking Backpack for Outdoor Adventures (Black & Crystal Blue) - Perfect for Camping, Travel & Daily Commute

I would not hesitate to get this slim backpack for motorcycle use if you don't need it for large amounts of storage. I did purchase a Klim hydration bladder to go with it.It's slim and functional but does not have a large capacity, so it suits me fine as I have other storage. It is extremely well made, has zippers and straps that are easy to operate with gloves on. I have a small tool bag, I've used the included tool bag to carry straps and carabiners, the optic pouch will fit a visor and has an included chamois.The chest straps are comfortable and have some small storage pouches with zippers. I also have a home for my Garmin In Reach which gives it direct access to the sky. I will say that on a slim rider the chest strap provides chest protection. I'm a big boy and the pads protect my armpits. Despite that it is very comfortable and I didn't miss having a waist strap.
