So I've been playing around with a topcover for the BB, and I have made one of these, as well as cutting out a pattern for future clones.
I will be posting instructions soon (my first 10 pics are stuck on the camera - the usb port is broken!), but I was wondering if anyone would be interested in playing around with this topcover and see how they like it. Me, I like a full sock instead of a topcover; but for the gram weenie, this is MUCH lighter than a full sock, and accomplishes the task of holding in heat while still being breathable. It is 1.1 ripstop, untreated.
I won't be checking back in to HF until tomorrow (it is Valentines day, you know,) so if you PM me or post something in this thread tonight, don't expect an immediate response.
