Hi does anyone wear a pfd or impact vest i dont but have been thinking If i get knocked out without it wouldnt be good

Nah have never been knocked out but thought it might make sense i think i bruised a rib last time i went out

Pfd I wouldn't bother with as it's generally not suited to waist harnesses. But an impact vest is good in certain situations, I use mine when it's deep water and a little flotation helps when you crash your kite or when I'm going full on and pushing my riding hard, for general free ride I wouldn't bother though.

Buy a neil pride high hook 50n impact vest and dont look back...
especially if you go out in the surf.

An impact vest will help you float and save some bumps and bruises...A pfd will save your life if you cant assist your self due to KO...

Kiddie arm bands work pritty well for flotation devices.

I have been involved in sailing from a young age and wearing a life jacket (PDF) is like using a seat belt in a car for me it’s now second nature and common sense and I always wear a PDF kiteboarding.
There are a lot of risks involved in kiting and a PDF helps minimise some of them (with PDF’s as with seat belts, there are people out there that don’t believe in them, but in majority of cases I would say a PDF with give more benefit then harm).
I am a very strong swimmer, but accidents happen and I would rather be floating comfortably after a heavy crash then worried about keeping my head afloat or looking “cool” on the beach. I find they also help when body dragging and water starting.

I wear a waist harness and find as long as I put the harness on first, the PDF sits snugly over the top. I do have two life jackets and must admit one of them isn’t very comfortable to use kiting so it’s about finding the right one for you. (PDF’s for Kayaking are often very comfortable and adjustable)

End of the day it’s a personal choice, but how often to you hear about a drowning where the person involved was wearing a PDF!

An impact vest adds another layer of warmth too, love my np impact vest

I've have had a Jet Pilot Nighthawk combination impact vest and type 3 PFD for some time now and rarely go out without it. I kite a lot mid week and am often out on my own. Certainly provides some protection in crashes, and the extra floatation is nice to have in some situations. I wear mine with the Dakine Nitrous board shorts harness and the two go well together and are quite comfortable.
