Hung out the last 2 nights here in Corvallis, OR. Had Gusts up to 40 MPH with medium-heavy rain. I stayed nice and dry under my MacCat Ultra with pole mod. I had the warbonnet superfly (with doors) set up first, but even with the side tieouts the tarp was whipping around, and I was afraid one of the guyouts might break off in a gust. Not so with the MacCat. The slimmer wind profile, generous cat cuts, extra side tieout and pole made all the difference! This thing was rock solid. This will be my go to tarp when high winds are in the forecast.
