Always though overwraps were frameless. My bad (y)
I think you will find the image is of the wrap over the Bivvy, the Bivvy front zips off completely if required so could explain why that part us not visible, if you are still unsure why not take a look at the Bivvy itself, it will soon become apparent. It's a trakker tempest v2 Bivvy, don't mistake or for the other half dozen variants the do.
It's funny how they are selling the wrap but showing a picture of the bivvy and no wrap in sight
I’m sure one of the discount codes will get you another 10% off the price.
