Wait, were you guys expecting $50 jackets? Nikes pricing has been like this for limited stuff for a long while now. The Olympic 21c Windrunner is $450+ and it is made of nylon and reflective material.
The Gyakusou Lunarspeed is only marked up by $20, that isn't that bad. Those other jacket w/o the Gyakusou styling and logo is probably only about $30-$40 less at retail. A typical Nike running tee could go up to $55 and the Gyakusou is priced at $75 (which is $100 at the NikeStore so it is already 25% off at MrP), heck this Nike Speed tee is already $70: http://store.nike.com/us/en_us/?l=shop,pdp,ctr-inline/cid-1/pid-523719/pgid-508666
The quilted hoody is $360 at NDC while it is $320 at MrP and the regular Nike running vapor jacket already retails at $300.
Of course we all know we are paying for the extra logo and a unique design/style so don't be too surprised at those prices.
