Frequently Asked Questions
Are these pouches fully waterproof?
No — the tomtoc organizers are described as water-repellent or water-resistant, which helps protect against splashes and light rain. They are not rated for full submersion. For gear that may be submerged, use a purpose-built waterproof case and a submersion-rated (IP67/68) power bank.
Can I charge my phone through the pouch?
These pouches are intended for storage and splash protection rather than in-pouch charging. You can remove the power bank or open the pouch in a sheltered spot to charge. Some users run cables out of a partially open zipper carefully, but that increases splash risk.
Which materials resist saltwater best?
Coated nylon and water-repellent polyester resist salt spray better than untreated fabrics. After exposure to saltwater, rinse gear and zippers with fresh water and dry fully to prevent corrosion. The premium nylon and water-resistant zippers used in the Performance model offer an advantage for frequent marine use.
