At the time I was sold on the dead air mask but I was looking at Silencershop, as stated dead airs were out of stock, so not being in a hurry to buy one I just put the idea on the backburner. I happened to go by McCoys outdoors in Mobile and as always got in a conversation about the dead air,just so happened they had one in stock but the guy behind the counter asked me had I considered the switchback. At the time I had never heard of the switchback so I came home and did my homework. After all the considerations I settled on the switchback. Both are rated the same but the switchback has a little more versatility plus the price was better for the switchback.Would you have chosen the mask over the switchback if it was in stock?
