The Boulder Aspen Slim Kits

Intentionally minimal. Boulder designed the Aspen Slim for people who want a vaping device that disappears into daily life—no bulky mod silhouette, no attention-grabbing clouds, just discreet satisfaction whenever you reach for it. At 5.67 inches tall and barely over half an inch wide, it slips into shirt pockets like a pen. The 720mAh high-purity graphite battery punches above its slim dimensions, delivering steady voltage throughout the discharge curve thanks to ultra-conductive contact points and energy-conserving microcontrollers engineered in-house by Boulder. Recharging takes just 45–60 minutes via Micro-USB, with the LED ring at the battery base pulsing gently to confirm charging status. A three-press safety activation button prevents pocket-firing—smart enough to protect, simple enough to never frustrate. The steel and food-grade polycarbonate construction provides surprising durability for something this light, while the premium textured finish ensures slip-free grip during use. Pass-through technology means you can vape while charging. An 11-second safety shutoff adds protection. Precision-engineered replaceable heating elements and cartridge tanks maintain consistent vapor quality across refills. Available in Blue, Champagne Gold, and Red.
