My mother's in her 90's and can still shower on her own; however, she can no longer manage a regular bath towel. With deterioration in her shoulders most towels are way too heavy and difficult for her to manage. She is pretty picky about absorbency and softness. Thank you!
Rainleaf Microfiber Towel
Quick Dry - Super Absorbent - Ultra Compact - Lightweight
Comes in a variety of colors, sizes and prices.
They are quite light and absorb well, but she may perceive them as being too thin, like a dish towel, but softer.
