I purchased four of these Esup 15L lightweight hiking backpacks for a family trip to Mexico, and they turned out to be the best travel purchase I made! These backpacks are incredibly lightweight and compact, making them easy to fold back into themselves for convenient storage. They fit effortlessly into my purse, allowing me to pull them out for extra carrying space during shopping trips or when more storage was needed. The straps are comfortable and surprisingly sturdy, providing excellent support. We now include these backpacks in our regular travel gear; they are perfect for hikes, trips to the park, beach outings, or even everyday use. One has even become our go-to bag for dog walks and hikes, fitting all our pup’s essentials easily. Their ease of packing and versatility makes them a must-have for any traveler. I would definitely purchase these again—100% recommended!
