It's rated IPX4 splashproof, meaning rain, sweat, splashes, and spills won't hurt it. It's also dustproof and shockproof with a rugged ABS + PC shell and reinforced rubber edges. Toss it in your backpack, clip it to your bag with the included carabiner — it's built for the outdoors, not a desk drawer. Just don't submerge it in water and you're good.
