I have a microfleece peanutshell. I used it alot when my DD was born last July and it was my favorite pouch out of my pouch stash which includes a WAHM fleece and the slingset pouch set, particularly for a newborn. I felt it had a perfect fit for me and DD and the fabric was stretchy enough for comfort without being too loose. The microfleece was very cozy without being too hot. I've never tried a hotsling but I've been very tempted many times to try one.
