I think the Kokatat ones look nifty, wasn't so big a fan of the Greenjacket, can't think why other than it's a bit 'gadgety' and the big moving frontpanel kinda seems weird in safety vest? Don't know if it's just me, but it's worth thinking about. Worth noting is that I have the playboating vest with the same panel and I don't wear it all that often, for the same reasons as above and almost never on a river. If you like the fit of the Astral vest try one of their
Aquavests (300r?), I use it and reckon it's it's got all the right bits in the right places. It has it's drawbacks but overall it's pretty cool.
Simon R. has the
Kokatat and Kill has/had the
Stohlquist, ask them if you can try them on and see what you think.
If I had to change mine today I would go for the same again or the Kokatat for the handiness of the entry zip.
Best of luck.
