Dakine Mission Pro 25L Backpack - Lightweight Durable Laptop Backpack for Travel, Work & School - Black One Size - Perfect for Commuting, Hiking & Everyday Use

Photo notes: Pack with Pelican 1400 stuffed in it are the ones with just a little bit of room at the top; still enough to pack a small lunch and make use of the padded goggle pouch. The pics with much more room are the pack with a Pelican iM2050 case stuffed down in the bottom.Review: I was recently looking for a backpack to take skiing for the purpose of holding camera equipment. Since it was for skiing, I didn't want one that would let water in, it needed to be tough, needed to have both hip belt and the shoulder strap cross section to keep it in place while skiing diamonds. The most frustrating aspect of this search was that most vendors websites, manufacturer or reseller, and nearly every Youtube review, of nearly every backpack, never takes interior dimensions into consideration. They all give this stupid cubic inch or liter rating, which is absolutely meaningless if you have a specific object you need to carry and you know its dimension.So, long story short, you can TIGHTLY fit an object that is 16.5" long (top to bottom of backpack), 12" wide (width of backpack), and 6" tall (backpack measured from your back to its rear exterior panel). You can get a little higher where the top of the pack begins to taper inward. My calculations put this well below the 1525 cubic inches Dakine rates it at, so perhaps they measure the interior capacity using water lol. I'm not going to knock them for this though, the pack is excellent, and it would just be nice if manufacturers would give max interior dimensions.An additional important note is that this pack DOES have a path from the pack through the left shoulder strap for a hydration tube, wire, etc. I believe the version of this pack from a year or two ago had that removed, when it had been there previously, people complained, and it has made a comeback.On the slopes, the pack fits just right and can be strapped down tight to not distract. It has held up great so far after a few cumulative weeks of slope days. Filled up, it is too large to backpack on the lifts though, so you're going to be carrying it on your lap.
