Product needs improvement

They are comfortable and good-looking. The bonded seam construction is neat, smooth and high quality. The pocket placement is unusual as it is more toward the center; so the content is out of the way when you lie on you side. The pocket design keeps a phone and small wallet stable and secure. The fabric looks and feels high quality. It is lightweight and quick drying. However, the waist elastic is a bit weak. My normal waist is 31" and the small waistband feels a bit loose when I have weight in the pockets. The draw cord bunches the front ugly. The pronounced seams of the waistband are right on the pointy hip bone, which may be uncomfortable under backpack hipbells. I prefer they had used a simple smooth wide elastic waistband.
