The Aspen Slim

Welcome to the best open system for vaping.
Precision, performance and pricing you'll love.

When you're ready for a high-quality, modular ecig that delivers consistent satisfaction day in and day out, the Aspen Slim is ready for you. We've designed this sleek entry to the Boulder system for maximum livablity and ease of use.

A three-press safety activation button keeps the Aspen Slim accident-free in your pocket or bag. Its powerful, high-purity graphite 720mAh battery packs plenty of punch and stays that way for long satisfaction, thanks to ultra-conductive contact points and energy-conserving microcontrollers designed in-house by Boulder.

Recharging the Aspen Slim is quick and painless through the supplied Micro USB cable and takes only 45 minutes. The LED ring at the base of the battery gently pulses to let you know that it's charging. Precision-engineered heating elements and replacement tanks ensure the same satisfying experience, each and every time.
