I have a Hit-Air vest. A couple years back the inflation time was reduced to 0.25 seconds. The older units inflated in 0.5 seconds. What is the advertised inflation time for the helite? I had the opportunity to "test" my unit while off-roading when I ran into a den of marmots..... similar to gophers. Their community is like a giant ant hill. When I hit it at about 15 - 20mph my front wheel immediately sunk in up to the axle and I went over the handlebars. Long story short - I think the vest saved my ass.
