Been following this with interest.  I'm in the group that doesn't usually wear a PFD - but I'm always in a group and have always been in Quetico when water was not especially cold and I could easily be in it for long time. No that I'm trying solo in a month,  I've sort of been thinking that I might want to wear a PFD.  My primary objection has been how hot and sweaty they make me, but then I've only ever had the basic Stearns vest. Someone point me to better choices?   Hoping I can avoid the $200+ variety that inflate but they may be the answer for comfort.  Thanks.
