Are roof bags completely waterproof?
The majority of our roof bags are crafted from water repellent fabrics and feature redundant sealing, such as taped zippers and storm flaps. We also carry one entirely waterproof bag. The Thule Sidekick Roof Cargo Box is crafted from a hard polyethylene shell that completely stops the elements from infiltrating your cargo. On the other hand, we do carry one bag which is not specially treated to repel water. The cost effective Thule Quest Bag is an excellent choice for summer jaunts and for people who live in arid or temperate zones.
