Two issues.  Both related.  One issue is that the upper section was too large and I purchased it according to the sizing info provided.  The second issue is the upper section has a draw sting where the tension is held in place by a clasp system that didn't stay clasped.  The material is quite.  The velcro works well.  The strap that goes under the foot is great.  Fix the other two issues and I would buy them again.
