Care & Maintenance

Empty the bag after use and allow it to dry completely before long-term storage. Rinse away salt, sand, dirt, or debris as needed and periodically inspect the roll-top, taped seams, buckle, and D-ring for wear or damage. Avoid packing sharp objects that could puncture or abrade the lightweight fabric.

Expert Insight

The Sea to Summit Lightweight Dry Bag is a strong all-around choice for users who want more durability than an ultralight 30D bag without stepping up to a much heavier dry-storage system. Its 70D fabric, 10,000 mm waterproof rating, white interior, oval base, and wide range of sizes make it especially useful for organized travel, paddling, backpacking, and dive-related gear storage.
