Very clever designs that mean they fit really well and wont budget
Made in Aus to the best of my knowledge.
I use to have the baggy ones, but that didn't work for me.A couple of years ago I found this type and they are awesome.When I drive back in my wetsuit when its cold in the winter I flip them over the head part and roll them on the chair. seat protected and you roll them up and take them of in a second.
