While the Pack Jack may have the appearance of a fun loving, beach going, better half (it is all of those things), don’t let its beautiful outer extremities fool you, the Pack Jack has the technical pedigree to protect you on any adventure.

A mighty material, this particular micro ripstop is also mighty nice feeling; our selection was made for its light, buttery smooth next-to-skin feeling. A breathable PU coating and DWR finish makes our Pack Jack wind proof and water resistant, while simultaneously allowing for your body’s moisture accumulation to escape.

Business in the jacket, party in the fanny. Not only is our Pack Jack an incredible looking, lightweight, first line of defense against the elements, it also packs into its built-in fanny pack!!

    Quickly became my favorite piece of clothing

    Ordered this for ski season but on a colder, cloudy day I used it for my bike commute and now I'm looking for excuses to wear it during the summer! This jacket is so light but does a great job protecting you from the elements without overheating you either. It also has an incredible fit for me (6'4, 195 - L), arm length and the shoulder articulation are great, and the elastic cuffs are the perfect amount of flexibility. The jacket feels great, and the pockets are just enough to carry your everyday items without feeling too busy. Love the colors, red/blue doesn't pop as much as the pics but it's got a nice understated look.

    Bonus points for how fun it is to transform into a fanny pack. I've shown this off to everyone I can when wearing the jacket!

    Game Changer - Life Changer

    My expectations were high ordering the pack jack and it still blew me away. It's super lightweight, comfortably stows a beer in fanny pack mode, and keeps weather at bay all while being extremely comfortable. Looks are great too, the photos online do not do the redwood color justice.

    Overall, could not recommend the pack jack enough, my only regret is when I forget it at home.

    Doesn't fit well

    Unfortunately the Pack Jack just doesn't fit really well. I love Trew gear and wear a lot of it and if there is any issues at all it is usually with the sizing. Not Uni-Sex sizing works at least with the Pack Jack.

    Thanks for making great products!

    Breathable comfort!

    Very happy with this addition to adventure wardrobe. It is the perfect layer for biking to work or hiking to hot springs in light rain/wind, very breathable, and practically weightless. The fanny pack feature is awesome for concert settings and biking across town (fits 12 oz can of beer). Thanks again for a great product, Trew!

    Thanks Daniel!
    Can’t live without

    The pack jack is the layer I never knew I needed, but now can’t live without. I wear my pack jack under my bibs for the perfect springtime top- it blocks the wind, it’s light enough to tour in, packs down to nothing, and gets all the compliments when im dancing during aprés. Also, in a pinch, turning your jacket into a fanny pack is the perfect party trick!
