The BCA Float™ E2-25 is the mid-volume sweet spot in BCA's airbag lineup — 25 litres of carry capacity in a low-profile, lightweight package purpose-built for backcountry and sidecountry skiing and snowboarding. Enough space for a full day out: beacon, probe, shovel, layers, food, water, and first aid. Low enough profile for heli skiing, guided sidecountry laps, and lift-accessed freeriding where pack bulk matters. At its core is the Alpride E2 supercapacitor system — 40% smaller and 11% lighter than the previous E1 — the most technically advanced avalanche airbag trigger system on the market. TSA-approved for airline travel. Three-year warranty.

The Alpride E2 supercapacitor is what makes the Float E2 fundamentally different from compressed air airbag systems. Where compressed air canisters store energy as pressurised gas — subject to temperature sensitivity, volume restrictions, and the logistical problem of refilling after a deployment — the E2 uses a supercapacitor: a device that stores electrical energy through magnetic charge rather than chemical reaction. The practical advantages are significant. Supercapacitors maintain performance in extreme cold, where compressed air systems can suffer pressure loss and slower deployment. They're classified as capacitors under IATA and DOT regulations, meaning the E2 system is not subject to the dangerous goods restrictions that govern compressed gas canisters — you fly with it like any other electronic device. After deployment, you recharge the system via USB rather than sourcing a refill station. Two AA batteries can be installed alongside the supercapacitor for additional deployments in the field: alkaline batteries add one deployment and maintain charge for up to three months; lithium batteries add three deployments and maintain charge for up to five months. Once triggered, the 162-litre airbag deploys around your head and shoulders, creating buoyancy to help you stay at or near the snow surface during an avalanche — reducing burial depth and protecting your head and neck from trauma.

The pack itself is built around how backcountry riders actually move. The Side Stash pocket is an external zippered compartment on the side of the pack — large enough for a water bottle, a layer, or a set of skins — accessible without removing the pack or opening the main compartment. In avalanche terrain, removing your pack to reach your water bottle means stopping in a potentially exposed location; the Side Stash eliminates that. The Back Stash zip is a second external access point on the back panel, designed for your BCA BC Link radio, a GPS device, or small accessories you need at hand. The dedicated rescue tools compartment is a separate zippered section with fast, unambiguous access to your shovel and probe — the tools you need in the first seconds after an avalanche. No digging through a full pack while someone is buried. The curved side access zipper allows you to reach the main compartment from the side without fully opening the pack — useful on the skin track or at a rest stop when you don't want to unpack everything to find something at the bottom.

The moulded "cooling fin" back panel is a structured foam panel with vertical channel cutouts — it holds the pack away from your back slightly, allowing airflow during high-output skinning and uphill effort while maintaining contact and stability. The frame sheet inside the back panel transfers load to the hip belt effectively, keeping weight centred even with a full load. Shoulder straps are dual-zippered and modular — removeable and replaceable if damaged, and adjustable for torso length (S/M fits 38–46cm torso, M/L fits 43–53cm). Hip belt pockets provide quick-access storage. Load lifters on the shoulder straps let you dial the weight distribution. Diagonal ski carry and vertical snowboard carry are both included. The pack is BCA BC Link radio compatible with a dedicated routing system for the antenna. Waterproof-coated 420d ripstop nylon exterior with DWR-coated YKK zippers keeps your gear dry regardless of conditions.

Frequently Asked Questions

How do I choose between S/M and M/L?
Torso length — not height or weight — determines the right size. To measure: stand upright, find the bony bump at the base of your neck (C7 vertebra), and measure down to the top of your hip bone (iliac crest). S/M fits 38–46cm / 15–18"; M/L fits 43–53cm / 17–21". There's overlap in the 43–46cm range — if you fall there, consider your build and how you like packs to fit. A correctly sized pack transfers load to the hips properly and keeps the airbag trigger handle positioned where you can reach it quickly. If you need help measuring or aren't sure which size to order, call us on 03 9421 2293 and we'll sort it out.

Can I take this on a plane?
Yes — the Alpride E2 supercapacitor is classified as a capacitor with energy storage of 10Wh or less under IATA and US DOT regulations, meaning it is not subject to the dangerous goods restrictions that apply to compressed gas airbag canisters. BCA recommends downloading and carrying the Alpride E2 fact sheet when travelling. No special declaration or removal is required beyond normal carry-on or checked luggage procedures.

What happens after the airbag deploys — how do I reset it?
After deployment, you deflate the airbag by opening the valve, fold it back into the pack, reconnect it, and recharge the E2 system via the included USB cable. No refill station, no compressed gas canister sourcing. The recharge process typically takes a few hours from a standard USB power source. If you have AA batteries installed, they allow additional deployments in the field without recharging — lithium AAs allow up to three additional deployments.

Does an airbag guarantee survival in an avalanche?
No — and BCA is explicit about this. The Float airbag system increases your chances of staying near the surface of an avalanche, reducing burial depth and protecting your head and neck from trauma. It does not guarantee survival. The most important avalanche safety measures are education, sound decision-making in the field, and carrying and knowing how to use a beacon, probe, and shovel. An airbag is a last-resort safety layer — not a replacement for terrain awareness and risk management. We strongly recommend completing an AST (Avalanche Safety Training) course before venturing into avalanche terrain.

Is the E2-25 the right size, or should I look at the E2-15 or E2-35?
The E2-25 is BCA's most versatile size — enough capacity for a full backcountry day without being bulky enough to slow you down on lift-accessed sidecountry or heli objectives. The E2-15 is the right call if you're primarily doing short sidecountry laps and want the smallest, lightest possible pack. The E2-35 adds an A-frame ski carry, compression straps, and more capacity for longer objectives with heavier loads. If you're doing a mix of day tours, heli trips, and sidecountry access, the E2-25 is the right call. Call us on 03 9421 2293 and we'll help you choose.
