So how easy are they to attach to each other, will the attachments stand up to use, what if your inner rug gets damp ... ?
I would sooner have two separate types of rugs; turn out and stable I think that I dont like staying in my work clothes and like to change the same as a horse kept in their turnout rug might feel?!
I'd be worried if the inner rug has the same chest fastenings as the normal thermatex. They inevitably slip or even come open if you leave them on over night, or at least mine do LOL!
