If you’re planning on hiking with the packraft, consider the Anfibio Buoy Boy PFD. I just got mine a couple of weeks ago and find it great for backpacking. If you aren’t headed out on class III or above rapids, it should do you just fine.
If you’re from the US or Canada, use the Swedish retailer linked. The German retailer refuses to ship to North America for Insurance reasons.
I’m currently in the process of modifying mine to add additional bomb proofing and features common in professional PFDs suitable for whitewater use. Should be interesting.
