Not so much a review as a recommendation. After a year plus of ownership, I reckon I've flown it enough in a variety of different conditions to have an unbiased view so here it is...
The vented Cosmic is in a different league to any other vented kite I've ever flown. Yes its eye wateringly expensive but its fantastic. It has a huge wind range (even more when you stuff the LE), and shrugs off gusty condiditions better than any other design I've flown. It is the only kite I've ever flown where the vented is virtualy as good as the standard and thats saying a lot given just how good the Cosmic TC is. it will do what the TC will do but in conditions where you'd pack up and go home if you were flying pretty much anything else.
Simply put, if you don't have a vented, don't spend your money on anything else. Save up and buy one of these. It really is that good!
N.B. I have absolutely no relationship with Kitehouse!
