Re: WM Auto/Manual PFD $140
The BassPro ones are red or blue, in addition to camo.
If you have a harness on, you do not need a PFD.
I like the option of choosing whether to wear either an inflatable PFD or a harness, or both. There have been incidents where a sailor regretted having an inflatable harness on - I believe there was one recently where someone was prevented from swimming down to detach someone else who was rendered unconscious from a sinking boat.
As far as the differences between inflatable PFDs, I have news for you. The retailer's name appears on a synthetic cover attached by velcro to the underlying inflatable ring and inflation device, so the underlying inflatable device sold by Defender may be the same one sold by West Marine, which may be the same one sold by BassPro.
The cover is different, the inflatable tube and device are the same. Of course, there are different versions of the device which triggers inflation and some may require differing degrees of immersion to trigger.
