I had a wool one for Kieren...I thought it was a bit 'blah' tbh...i didnt like the fit and didnt like the inserts...I also think they are expensive I tried it at night and we got leaks even boosted with an 2 EP hemps... I wont bother trying one again
I do like them, they were my absolute favs when DD was in size small, used them both day & night. Now when she's gone to mediums they feel a bit bulky (the M/L insert being a tad too big for medium cover) but still it's our favourite for night time. However, then I stuff it with a trifold made of 5 layers of stretchy bamboo terry wich lasts the whole 12 hrs (with 3-4 feedings) and no leaks. It's a shame the wool cover looks worn pretty quickly but it's always possible to shave the bits off (don't know what you call them...).
We loved our wool ones - we did use different inserts though - and ours didn't look worn quickly either... They are expensive new for what they are though and I wouldn't use them overnight as they suggest but I'm a big one for fitteds overnight
