Familiarity: I've used it several times
Got a sweaty dome? Suffer from a soggy noggin? Step right up folks and plunk a Catlike Whisper on your head. I busted up my last helmet crashing into a bollard so I needed a new lid. After some research and reviews (Thanks Backcountry for the cool video review) I picked the Catlike. I'm extremely impressed by the fit, the weight, and the ventilation. It fits better than your favorite pair of jeans. It's virtually unnoticeable (unless you can feel a butterfly resting on your follicles) when strapped on. It's like wearing an industrial evaporative cooler, minus the big square metal box and the bulky water pump. And... the colors are pretty bad-#$$.
On to the downsides... minor as they may be. The helmet industry hasn't adapted concussion-reduction standards, therefore the Whisper doesn't have that feature. A guy can dream. Wishing aside, it's on the expensive side, but you do get what you pay for.
