Sporasub scarpin sandwich 3mm
Good to wear. At first glance (first use on weekends 29/01/17) good quality. Nice and warm.
Bad choice !
These shoes are very good and very flexible, but I put just my choice because d'avoir taken 3mm for winter. So slippers 3 mm for a minimum of 16 degree water. Below 16 degrees, take the 5 mm.
