Although this Vbiger pack doesn’t have any extra bells and whistles, similarly-sized CamelBak hydration packs are $50 or more. You can get this one for just $7 with promo code TKMF82X2.
It features all the essentials: hands-free hose, room for your phone and keys, and waist strap. It’s perfect for the casual user who doesn’t need to spend too much to hands-free hydrate.
