Airblaster Grumpy Jacket: although it may appear rough and rugged (which it is in some cases) the Airblaster Grumpy Jacket was designed to hold you like the old man on the porch holds his shotgun; with a loving embrace. This critically seam sealed Nick Dirks special carries a 10,000mm waterproof rating and is stuffed with 100g synthetic insulation for solid weatherproof protection that will make you un-grumpy. That’s the Grumpy’s mission; to carry the burden so you can ride free and clear of discomfort on the mountain. Designed with a long cut and new shirt-tail hem cut the Airblaster Grumpy Jacket offers us the confidence in comfort and impeccable styles of our gun-toting trigger happy grandpa’s. God bless’em! With added features including a removable hood, removable powder skirt, and mesh lined pit-zip vents the Airblaster Grumpy Jacket works hard to shoulder the burden.
