Frequently Asked Questions
Will a dry bag keep my phone safe if I get caught in a sudden downpour?
Yes — when used correctly, a roll-top dry bag creates a watertight seal that prevents rain from reaching contents. For phones, use an IPX8-rated phone sleeve inside the bag so you can safely use the touchscreen and take photos without exposing the device to moisture.
Can a quick-dry towel replace a waterproof bag if my backpack gets wet?
No — quick-dry towels help remove surface moisture and speed evaporation, but they aren’t waterproof. Use a towel to dry pockets and gear, then store electronics in a sealed dry bag or IPX-rated case to ensure full protection from ongoing rain or puddles.
How should I pack a dry bag to protect a tablet or laptop?
Put the tablet or laptop in a padded sleeve first to protect against impacts and pressure, then place that sleeve into the dry bag. Roll the top at least three times, clip firmly, and double-check seams. Keep heavier items lower to avoid pressure on fragile ports.
