The zipper quality on the Staika is by far the best I've experienced in tents. The new Niak uses the same. It does not pinch like so many other tents do. The zipper has a very thick cover to keep the moisture out. Trust me, I've had many tents in my life and there is a reason why I am enamored with Hillberg's tents. All other tents in my past life always created stress in the middle of the night when the zipper pinched, no more with Hilleberg!! I am stress free.
I think I like it inside the bag to keep it clean and dry with my sleeping bag and bed.
