Yes and No. In a gathered end, the fabric is all "bunched up" and usually covered by my UQ, so a single layer of 1.9 is really folds of 1.9, whereas in the bridge, a single layer of 1.9 is a single wall of 1.9, can't be covered by a quilt, and there is a lot of breathing through that straight wall of fabric if the wind hits it. Great Hammock, but the gear hammock/pack cover or slowhikes "storage end covers" are recommended (by me, anyway) for winter use on the BMB.
