I just got a loveybums fleece cover in, it is very nice and trim especially compared to my stacinator fleece. I don't usually trifold so I don't know much about how a cover needs to be to secure that, but this cover seems like it might work.
mmm....i think my advice to you would be to use a wool cover that's a little tighter than stacinators and if your child won't open it..velcro. I seem to always get a tighter wrap with velcro than with snaps...maybe because mine won't sit still so i'm working against the clock to get a cover on LOL.<br><br>
Btw...stacinators run a *little* big imho which is why you're probably a little bulky <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">
