I bought xl underjams off of ebay and Im pretty slender... 5'10; 140 lb; 28- 29" Waist. However the sides rip within 15 minutes or so. I did modify 1 of them with saran wrap taped and stapled to the sides in order to allow for a larger waist size. This worked to an extent but it was very time consuming and after 2 hrs, the rubber sides had significant tearing and where about to break.
I like the underjams diaper because of how thick it becomes after it becomes wet. The Jell density is much greater than goodnites.
Does anyone have any modding suggestions? Is there a simple way to combine them with regular underwear?
