Because airbags weigh enough as is.
The airbag itself features a gas canister deployment (cylinder sold separately) through dual air chambers around your neck, head, and sides for increased shock absorption and overall reliability. There's a chance an avalanche could pop an airbag, but this bag's dual chamber design can help you stay afloat if only one chamber pops. Arva made the safe-locking, retractable handle completely adjustable so you can place it right where you want.

- Q & A
Does the stated size of the ARVA airbag packs include the volume that is taken up by the airbag and deployment equipment?
As a rule for all airbag packs, yes. The advertised capacity does include the volume taken up by the system. That said companies are getting very good at maximising the usable volume even with the system. I have not gotten the chance to use this particular pack but the general rule is 2 liters less than what is advertised. I recently took a look at the Mammut Light 30L airbag and found it to be very spacious and it comes in at only 4.5 lbs, 5.4 lbs with the cannister.
