Silo Dry Drop 10L Bag

Fully Waterproof 500D PVC Construction – Roll-top closure creates a watertight seal that keeps rain, mud, dirt, and sand completely outside. Your backup batteries, dry socks, and emergency layers stay protected no matter what conditions hit the aid station.

Just 9.5 Ounces With 10-Liter Capacity – Packs enough gear for a full aid station resupply without weighing down race staff or your crew. The compact design rolls small when empty but expands to hold clothing, nutrition, and electronics securely.

Modular System Compatible With Roll Drop – Slip the Roll Drop organizer inside the Dry Drop 10L for the ultimate protection—your mesh pouches stay organized while everything remains waterproof. One integrated system that scales from training runs to 200-mile races.

The 500D PVC fabric isn't just water-resistant—it's fully waterproof with heat-sealed seams. The roll-top closure creates an airtight seal by folding the opening three times and securing it with side clips. This protects your gear through torrential downpours, aid stations set up near streams, or race staff accidentally dropping bags in puddles.

How to Use Dry Drop 10L Bag

Load your Roll Drop organizer or gear directly into the Dry Drop 10L. Roll the top down tightly three times, then secure both side clips. The watertight seal protects everything until you reach the aid station.

Use the Dry Drop 10L for kayaking, beach days, camping, or any activity where gear needs waterproof protection. At $17.99, it's affordable enough to keep one in your car permanently.

Pro Tip: Before your race, test the seal by closing it around air—roll the top, clip it, then squeeze. If air doesn't escape, your gear will stay dry through anything.

Ultrarunners use the Dry Drop 10L at races notorious for weather changes—Leadville, Hardrock, UTMB—where afternoon thunderstorms can soak unprotected drop bags.
