If the IR jacket seems to be leaking thru the seams, you can send that in to us at IR and we can test it, and see if there are any holes- we typically do those repairs at no cost to you, aside from shipping to IR. We have changed our waterproof/breathable material in the last couple of years as well, something to consider if you want to upgrade to a full-on drytop. The Semi-dry jackets are designed more so with river-running in mind, not so much for playboating. The Comp LX (full latex)would be the way to go if that is how you find yourself spending most of your time- as you tend to flip more/be upside down more while playboating.
As for your sprayskirt, if you are indeed using the same skirt for the dagger, as you were for the Burn, chances are, that it is pretty stretched out, and its time for a new skirt- they do get a bit worn out over time, and the burn is a XL cockpit, the Dagger rims are on the bigger side of a large- between those two rims, they have a circumference difference of about 5-6", which is a lot. You can check out Skirtfit.com
if you ever need to know the size of a cockpit rim. Our klingon sprayskirt seems to seal well on the Dagger rims. If you ever have any questions on any of our products, we always welcome a phone call, between 9-6:00 eastern time- we are always eager to help you out!
