Much better than expected.
I’m actually shocked by how well these compression bags work. I was able to fit so many packing cubes and big dresses in one of them that I lost track of how much I fit in my luggage and at my destination was convinced I forgot to pack all my shirts. When I unzipped my Esker bag and started unpacking, I found my shirts, compressed into another dimension, tucked away under a big coat and gown.
If you’re on the fence about these bags, I can’t recommend them highly enough.
