Right around this time last year, I wrote a post about the ISPO Brand New Award finalist Biknd Helium case. And true to plan, the case is now available for sale.
The $600 price tag is rather expensive, but if you do a lot of bike travel, saved bike rental fees could pay for it in a hurry. The soft case uses inflatable air cushions to keep your bike traveling as safe as you--safer if you happen to get stuck next to a fat guy with wandering elbows. It comes with a hand pump for inflation.
You can find it at Huck N Roll and other bike retailers.
