Ranked in these QuestionsQuestion Ranking
Pro Includes raincover
A raincover comes with the pack.
Pro Lockable zippers for security
There are locking zippers on both the main compartment and laptop compartment. The zippers are close enough together that you can use the same lock for both.
Pro Straps can be stowed away
The straps can be zipped away, giving the bag a slimmer profile (more suitcase-like), and protects the straps from damage.
Pro Three-dimensional zippered pockets for organization
Two pockets inside the main compartment are three dimensional, acting as built-in packing cubes.
Pro Women-specific version available
There is a women-specific version of the REI Trail 40 available, which has a slightly smaller torso fit range.
Pro Pockets on the hip belt for easy access
The hip belt has two zippered pockets which lets you store things for easy access (such as papers, money or snacks).
Pro Four zipper access to easily get to your belongings
The pack is front load with four zipper access, allowing you to unzip from either the top or bottom. This is great if you want to grab something from the bottom of your pack without opening it completely.
Pro Includes raincover
The pack comes with a rain cover that stows away in it's own zip pocket.
Con Hip belt sold separately
There is a hipbelt available for the Minaal, but it will be sold separately.
Con Pocket for hydration reservoir is difficult to access
The pocket for the hydration reservoir is external, located right behind the back panel. There is very little room, making it hard to access and can only fit a small amount of water (around 1.5L).
Con Internal bungee compression system can get in the way
The internal compression straps are a bungee system, which does not unclip the way most do. When your pack is full, this can make it a very tight squeeze if you want to access something in the back.
