BCA Float E2 Avalanche Airbag Pack

Instead of using compressed gas cartridges, the E2 system uses supercapacitors to power the fan that inflates the airbag. This allows for multiple deployments on a single charge and eliminates the need to replace or refill canisters after use.

Yes. Because the system uses supercapacitors rather than pressurized gas cylinders or lithium-ion batteries, it is not subject to the same TSA or airline restrictions as traditional airbag packs, making it much easier to travel with.

You can recharge the supercapacitors via a micro-USB port or by using two AA batteries. It is a straightforward process that ensures you are ready for your next outing without needing specialized equipment.

The 25-liter capacity is ideal for standard day tours, offering enough space for your essential safety gear, an extra layer, snacks, and hydration. If you typically carry significant extra gear or camera equipment, you may find it tight, but it is well-suited for minimalist, efficient backcountry travel.

The supercapacitor technology is specifically engineered to maintain consistent performance in extreme cold. Unlike some battery-operated systems that can struggle in freezing conditions, the E2 is designed to be reliable regardless of the temperature.
