The Cargo Hold 37 Panniers transform the HSD into an incredibly versatile transport solution. These panniers function as your mobile car trunk, ideal for hauling groceries, a convenient backpack for errands and commutes, or a spacious diaper bag equipped to carry toys and baby necessities. For ultimate convenience, you can easily fold the sides of the panniers to switch to a hassle-free "Bucket Mode," which also accommodates a Yepp seat if you need to transport both your little one and your shopping. When used with the GSD, the Cargo Hold 37 neatly fits either behind an adult passenger's legs or behind a single Yepp seat, making it an adaptable addition to your transportation setup.
