Similar to the original Allpa Travel Pack, this 20L version is perfectly sized for anyone who prefers a smaller pack-whether that's for a day trip or for your kiddo. This pack will stand up to the wildest of adventures with 100% recycled, super durable, and water-resistant fabric. We kept the carry as comfortable as possible with a foam back panel and adjustable shoulder straps. And make packing easy with a suitcase-style opening loaded with internal zip pockets.
