Sleepsack recommendations

Our little girl has learned how to pull zippers. So she can break out of her sleepsacks. We have both the sleep sacks with the zipper down the middle and one one that zips around the edge of the sleepsack. She pulls toward herself so the 2-way isn't helpful anymore. We don't do diaper changes in a sleepsack anyway. There are no snaps or stuff to cover the zipper tabs that have kept her from unzipping.

Anyone know of one-way zipper sleepsacks or "child proof"?

She is in the largest sleepsacks of the brands that carry larger sizes. Some brands she cannot fit. She's 30lb and 33inches tall.

Help! I love sleepsacks for her. I'm not ready for blankets and jammies.
