They say the 80s are back, but did the 80s ever really leave? Founded over 40 years ago, Mountainsmith knows the 80s, and they know packs. So, they stepped into their neon ski bibs, pulled on their oversized sweaters, freshened up their mullets and dug through decades of old workbooks, stories, and photos to bring a truly authentic 80s design inspired by the archives that started it all. Meet the Trippin Pack. With a 22-liter main compartment, front panel accessory pocket, internal organization, and interior back panel sleeve, the Trippin Pack is designed as much for the everyday dirtbag as it is for the daily bike commute.
