The Port Kitt feels sturdy and made of high quality materials. The toiletry pouch is waterproof from outside and its inside pockets, and is easy to clean. The rubber loops inside are tight but slightly wider than usual bottles will be unlikely to fit through without really stretching it. The tech pouch has outside loops that I used extra straps from my Errant pack to turn it into a small bag to carry around. Only the tech pouch can be attached inside my Errant using the fidlock, but it's quite fiddly to remove, and the toiletry pouch will have to be stored separately during that time. If the outer pocket on the tech pouch was lined with felt instead, for keeping a phone or other more delicate tech stuff, would've made the tech pouch better. Besides the fidlock, there's also a button pin to secure both pouches together, and when separated, the flap of the pin can be pinned onto the tech pouch into a loop so it doesn't just hang around, which was a thoughtful design. The hypalon on the outer zippers on both pouches feel nice, but I do worry they will break after a number of years (my Errant's which I've had since it's release has recently broken, and I don't pull the hypalon at all to use the zipper). The whole thing came in a cloth bag that can be used for other stuff when the Port Kitt is not being stored, which was a nice surprise. Overall, I appreciate that if I'm just a tad "creative" with the modular parts of the Errant and Port Kitt, they're a versatile combo for daily…
