Shield 23L InLock Waterproof Backpack Pannier

What Our Gearhead® Experts Are Saying:

"I like this bag for longer commutes where I’m riding in and carrying everything the rest of the day. It stays dry in bad weather, rides quietly on the rack, and feels like a real backpack once it’s off the bike."

Some rides don’t end when the bike gets locked up, and the Shield 23L InLock Waterproof Backpack Pannier is built for exactly that kind of day. It handles the ride in and the walk after without asking for a gear swap, making it easy to move from commuting to work, meeting friends, or heading to the gym. Waterproof construction with welded seams helps keep gear protected through rain, road spray, and unpredictable conditions.

The bag slides onto an InLock mounting panel and locks into place with a secure, rattle-free connection. A soft mounting interface minimizes vibration while riding, and a quick-release tab allows fast removal at the destination. Backpack straps and a hardware-free back panel improve comfort when worn, making it easy to move through the rest of the day on foot. The Shield 23L InLock Waterproof Backpack Pannier is best suited for all-weather commuters and everyday riders who want waterproof protection, quiet rack performance, and a single bag that works on the bike and beyond.
