Climbing up Engineer Pass in Colorado's Rocky Mountains is a major accomplishment, & our Colorado Pass sticker series is a fun way to remember it. The breathtaking scenery is a favorite of Jeeps, ATVs, UTVs, overlanders & ADV motorcycle riders who love to brave this treacherous alpine terrain. Great bumper sticker for your Jeep, 4x4 window, rooftop cargo box, or motorcycle panniers and helmets. Perfect waterproof sticker for Hydroflask water bottles, thermoses, or coolers. 2 sizes available, including a smaller 2" size so you have plenty of room to collect more of our Colorado decals, inspired by the CO state flag! Small: 2" diameter. Large: 3" diameter. Durable die-cut waterproof vinyl with a matte UV resistant finish for years of use indoors & outdoors. Made in Texas. Looking for a specific mountain pass?
