The Dakine Storm seat harness is a comfortable, durable, value for money harness.    I have been using the harness since Feb 2006 and have not had any problems with the harness.  The harness has been used for buggying, landboarding however mostly kiteboarding.  

Comfort
The harness is generally comfy being used for Kiteboarding or Landboarding.  It offers relatively good lower back support, and doesn't twist or shift.  If the leg straps are not fitted correctly, or the harness is slightly large it will ride up a bit and give you a wedgie.  This also occurs if you spend a long time with the kite above you and the general force and pull of the kite slowly encourages the harness to ride up.  This is not so much of an issue if you fit the harneess correctly.  There are adjusters for the back support, tightness of the harness, tightness of the spreader bar and leg adjusters.

Spreader Bar
The spreader bar is good, and is also slightly longer then the equivelant Mystic style spreader bars, and has a good hook shape to it.  Due to the shape it does require you to pull more towards you to unhook, opposed to some other style harnesses where you can nearly slip the chicken loop off with minimal effort.  

Get the Pad!
When you purchase this harness make sure you get the spreader bar pad with it, the harness becomes a lot more comfier.  Without it and you will most likely end up with a number of bruises from the force of the spreader bar against your body.  When choosing the Dakine Spreader Bar Pad check that you are getting the correct size pad for the bar.  The spreader bars come in different sizes, and so do the pads that go with them.  You need to pull the hoops of the pad through the spreader bar, then connect the pad's rings to your harness.  See the photos of the Spreader Bar and Pad together to understand better.

Strapping In / Out
Getting in and out of the harness is quite easy.  The harness has a hook style quick release, that allows you to clip the spreader bar on and off very easily, and has a screw to ensure that one side of the bar is always connected so you don't loose it.

Durability
The harnesses are an excellent general purpose harness, and do everything well.  The harnesses higher up in the Dakine range are built a bit tougher, and are more durable.  However the Dakine Storm has lasted me two years already.

Overall
Since purchasing my harness over two years ago the price of the Dakine Storm has dropped considerably, and therefor remains still as one of the best value for money harnesses available.  If you are pushing the limits, and very hard on your gear it may be wise to look up a model or two.  If you are just starting out like I was when I purchased it for the water, then it is a fantastic choice to go with.  Remember to go in and try it on before you buy one!
