First off, I have been a loyal Brenthaven customer for many years. I recently decided to switch because the Brenthavens although well made, are far too bulky and their lifetime warranty seems to only cover the zipper pulls. I wanted a less-bulky backpack with a decent warranty and I think I found it in this Pelican model. I was originally going to purchase the 20L model, but am very happy I chose the 25L model as the size is just right. PROS:Well made, Waterproof, durable material, comfortable straps. CON:This is a big one for me and the primary reason I could not give this product 5 stars. There are 2 main compartments, 1 for the laptop and tablet and the larger one for everything else. The main compartment has a SINGLE pocket even though the product description claims ''Large main compartment with organization pockets''. This may seem trivial, but when trying to organize, the one packet and straps (for lack of a better word) just aren't enough.
