Black Diamond Avalung, original vest style, size medium, same functionality as current sling style, but in the form of a vest that you wear as your final layer.
Has a large zippered outer pocket and a small zippered inner pocket. (Another zippered inner pocket accesses part of the Avalung device, so might not be a great idea to use that third pocket for storage.)
Condition is essentially new. The wrapped was removed from the mouthpiece, but I can’t remember if it was ever actually used (or if the wrapper was instead removed just in preparation for possible use on a trip).
Price is $38 plus actual USPS priority mail shipping from 01002. (Paypal is free if drawing on paypal balance or checking account, but additional fees for credit card use.)
