AVABAG LiTRIC airbag from Arc'teryx & OrtovoxAvalanche airbag system designs have evolved significantly since the 2000s, coming a long way from the initial prototypes unveiled to public in 1985. These days, whether you choose to go electronically-activated or canister-powered, both systems rapidly inflate to increase your probability of survival in an avalanche, and have pros and cons regarding weight, fan requirements, number of deployments, the re-packing of the bag after deployment, etc.

Ortovox and Arc'teryx have recently released AVABAG LiTRIC, an award-winning electric avalanche bag. Coming in at around 2.4lbs and a fully-charged battery that can deploy twice within a 60-hour period, it's worth taking a look at. Check it out!
