I have last year's Viper 10 and I love it, is this pack worth the upgrade regardless of the money? What does anyone out there who has it have to say about it?
Here's a review that might be helpful. http://youtu.be/FPB0VavUr_M
Also, you can go directly to www.ospreypacks.com, and do a compare for both the current model, and the previous years' models.
Click on "past seasons" packs...click on the model you're interested in...then look at the speck on the tab at the top of the window.
Then you can compare to the current season's model to see what, if any, improvements have been made.
Hope this helps!
