When I worked as a UI designer, there were several times when I had the opportunity to design for entirely new hardware devices. During the process, we would usually have prototype versions of the devices at various forms of completion. These could cost in the tens of thousands of dollars per unit and there were a handful of times when someone on the team would accidentally have one one fall off of their desk onto the ground. “Drop test!” everyone would exclaim in a half-joking, half-panicked tone. Everyone would be very happy if it passed.

Slim Pack Perfect Backpack Waterproof

Water Test of the Slim Pack Commuter Backpack

Well, a backer recently had the accidental opportunity to put our waterproof commuter backpackthe Slim Pack, through its paces during a flight. As he described:

"Just wanted to send a quick thanks/kudos for the Slim Pack. As it turned out, I received mine the day before we left for a week-long vacation in Mexico.

I had already planned to bring my laptop, so naturally took the opportunity to try out the new pack. Used it as my carry-on, with laptop and some other supplies. What happened next was great. As the slimpack was stowed under the seat in front of me, the air pressure from the plane popped open the person's water bottle sitting in that seat. She didn't notice as it slowly leaked almost a liter of water out beside the seat, directly onto the slimpack.

When I eventually reached for it, I discovered that both it and another bag I had under the seat there were drenched. Everything inside the other bag (nothing important fortunately) was also soaked. Slimpack contents though, including my laptop, were bone dry. (The exterior dried off quickly too.)" -Nathan

In my testing, I can control certain variables such as water intensity and exposure time… but in the field, conditions are more realistic. So far with rain and now this in-flight water torture test, it’s shown to hold up really well in real world scenarios.

Another backer shared his experience:

"Dave, I received my backpack in the very first batch sent. It is incredible. It was put through its paces this weekend at the NAMM show in Anaheim CA during our crazy weather. It handled the rain with no problem, and for those not in CA, this was an exceptional amount of rain. I carried my DSLR and my iPad in it with no fear. Truly impressed with the comfort." -Sam

We’re making great progress on the backorders and they’re coming out great… looking forward to getting them in the hands of the rest of the backers!
