Love this cover--thick, soft, gorgeous green color. I mostly use it at night because it is so bulky.  This actually keeps my guy's sheets dry all night long!  The trick with wool is to make sure you have enough absorbency inside--after playing around with it, I have settled on a Pooters hemp fitted with a hemp soaker and a tri-folded small prefold inside.  With so much bulk, it is hard to get a good fit with PUL covers--they tend to gape at the waist--but this cover's stretchy wide waist and leg bands hug the body and prevent gaps, even over the bulky extra-stuffed fitted.

I ordered the 98/104, 2-3 year size for my big, tall, long-waisted 6-month-old.  Glad I got it rather than the 86/92.  It is roomy on him for now but that's okay, it still works fine and we'll get a lot of use out of it.  I really have to size up his PJs to get them over this giant nighttime diaper combo.  In warmer weather, I put him in it during the day with just a little t-shirt on top and it looked super cute.

The reason for 4 stars is that this is a bit more complicated to use than the other wool covers I've tried (Kissas, Woolybottoms).  There is more work required to prep this one.  It took some trial and error, but after washing/lanolizing it twice, then doing a third extra-long lanolization (I let it soak for half a day in a water/melted lanolin solution), it is working well.  I'd read I was supposed to hand-felt the crotch area before using but I gave up on that and I find that it is quickly self-felting just from use.  The open weave also requires that you really figure out your sufficient absorbency underneath.  But in the end it's worth it for the excellent performance.
