I have just discovered a "low rider" in non-plastic. Gary Mfg is now offering PUL pants and I ordered both the standard cut and the extra rise cut. I was happy with the extra rise; it is more than adequate to cover a night (cloth) diaper fully.
I was disappointed that the standard cut is too brief for covering a day (cloth) diaper but it is fine for covering a disposable diaper.
I find the PUL (poly urethane laminate) very comfortable. The cloth outer is smooth and most likely nylon or rayon. The inner suface has been treated with urethane to waterproof the fabric.
I also have the Kins Low Rider vinyl pants (for wear over disposables) and I think these Gary PUL pants are very similar in the cut to the low riders.
Order your size in the Polyurethane Laminate Pant, Pull On, Regular Pant Cut, and add Comfort Style for $2 which is covered elastics at waist and legs. Yes, they are costly.....mine are size Large and cost $21.99 each.

I'll bet you'll like the fit and feel of the Gary PUL pants.
