Where did you get the gaiters?
Made them myself on sewing machine from WaterProof Polyester Cloth (Two Layers) and Non Adhesive Velcro Strip (no tacky Glue).
The Bottom Ones are similar (my modification) to the DaveW Design (Dave may supply a set in his Mohair Hood Fabric if you send him a PM request)and the Top Ones My Own.

I hope this helps.
