Right! Great strides have been made. Why, they just recently discovered "wind buffers"! (Isn't that what you called them years ago?) Now they're "saddle bags." I invented them myself just two years ago ....
Did a search; they were "wind bumpers".
The side view of the TravelPod shows that no extra cloth is used. The bumps pushing out on the sides of the hammock are WindBumpers, described on another page. You may be able to see how the WindBumpers create an air space between the hammock and the TravelPod for the essential four central feet of the hammock.
