Lightweight/single-layer footmuff for BJ Versa GT?

[Laquila]

I have a Kaiser Multifunction, which I love, but it's too thick and warm for spring and summer - can anyone recommend anything thinner that would work on the Versa? Ideally I'd like something that sort of works as a cocoon, so that it goes inside the seat and the straps come through it, with another bit (preferably removable) that then goes over the legs and feet.

Thanks in advance for any help :)

The normal buggysnuggles are lightweight, just a fleece layer on top.

I love my sheepskin and stay put blanket for warmer weather as the sheepskin keeps them Copland the blanket fastens onto frame so doesn't fall out, I think it allowsmoreairflow than a normal footmuff.

Cool not Copland lol

Oh god the typos... Can you tell I have a new phone?!
