KLIM Nac Pak Technical Backpack - Waterproof Hiking Backpack with Laptop Compartment, Gray - Perfect for Outdoor Adventures, Travel & Daily Commute

I use this pack for enduro rides and find it to be the perfect size for that type of riding. Not to large and bulky but not too small either. I also own the Klim Crew pack which I thought would be a good pack for dual sport and enduro and found it to be too large for most enduro/trail rides. I was a little worried about the security of this pack on my body since it doesn't have a waste belt, but it fits great, feels secure, and gives very good freedom of movement on the bike. The included tool kit pouch is a very nice feature. The only gripe I could have is that it doesn't come with a bladder, but I just transfer my bladder from the Crew pack or any other hydro pack I have when I use it. The construction quality is very good IMHO and the layout of all of the storage compartments was very well thought out. I love that there is a compartment on the front of the vest that will just fit my iphone 7. Nice to be able to get to your phone or keys without having to remove the pack. A phone larger than a standard iphone 6 or 7 probably won't fit in that pocket though. I fell off of a trail on a recent ride and ended up landing on my back and sliding 20 feet or so in the rocks down a steep hill. The pack suffered no damage and it protected me from the fall. Like all Klim products that I own, it is a quality product.
