"Pack well, go far with the Boulder backpack. Made from ultra-soft recycled materials, the Boulder easily packs into an internal square pocket, perfect for a ride to the shops, or to stash in your luggage and bring out for day trips. With air mesh panels and straps for comfort and breathability, sternum strap, internal pockets and side compression tabs, the Boulder has all the functionality of a large backpack with pack-and-go ease."
