TimUIf you're referring to the Massdrop version of the Static V, then the difference is two-fold:
1) these pillows are being drop-shipping directly from Klymit, which helps us with the amazing price but int'l. shipping is unfortunately higher
2) the Massdrop x Klymit Ultralight V has free US shipping / discounted int'l shipping.
So the pillows are more expensive than normal to ship, and the Massdrop pads have subsidized shipping. Keep an eye for the Massdrop x Klymit Pillow X starting later this week, which will have free US shipping / discounted int'l shipping. I think it will be like $3-4 for shipping to Oz.
