Pac Jac: Compact, Durable, and Ready for Anything Packable pocket. Carry on. Armpit gussets. Punch that glass ceiling. Reinforced elbows. Stay sharp. Weather protection in the palm of your hand The 3-season Pac Jac wards off morning wind and rain. When the sun comes out, Pac this Jac into its own chest pocket. Toss it in your toolbox, backpack, front pocket of your Freshley overalls, or hang off your carabiner. In addition to packable magic, a potion of PFAS-free, plant-based repellency makes the Pac Jac water and stain resistant. Ultralight ripstop is breathable, and UPF 50+. This lightweight toughie can take any blows you throw at her: super-strong Cordura® fibers fortify the fabric, so you won’t snag on thorny plants, nails or other prickly situations. We chose Kelp Green and Jasper Orange to complement the other styles in our Springtime stash. Mix and match, or for a full ultralight weather-proof ‘fit, pair the Kelp Pac Jac with our new Anna Trail Pant in Kelp.
