We have one double gusset. I love it! I use it at night, stuffed with hemp. Our other night diapers are bG 4.0s. The fit of the Alva is way better. I love how stretchy the PUL is.
I ordered directly from Alva. Free shipping. It took about 2 weeks, and there was no tracking. I was a little nervous, but for $6? Totally worth it. If I ever need more diapers, I'm going Alva!
