I currently have a "full" life jacket that I use when I'm dinghy sailing but trying to break into racing I see a lot of people have these cool "off shore" lifejackets that are very low profile. I guess they need a cartridge to inflate, and then once they are used you replace the cartridges?
something like this:
What do you recommend or use?
Also how universal are the cartridges, and how much do they run for in general (the cartridges)? Are they one size fits all or what?
Any help or advice is appreciated! Cheers!
