Thanks for that info, TS. Strangely, I kind of like the Velcro on my PeaPod. But I have always had a lot of trouble in the past with the zippers on my mummy bags wanting to snag when I am either in a hurry to get in ( c-c-c-cold, must hurry!) or even worse, when I am in a hurry to get out. Generally, because of no snag of fabric in zipper, it is much easier/quicker for me to get settled in the pod, and WAY quicker on getting out. But, if I just ever had a zipper that did not catch on the bags fabric, I would probably prefer zippers also.
