What GSM should I look for in a hand towel?

GSM (grams per square meter) describes weight and density. Lower-GSM towels (around 400) dry faster and feel lighter, while heavier 600 GSM options like the American Soft Linen set feel plusher and more absorbent but take longer to dry. For powder rooms and quick hand-drying, mid-weight is usually the sweet spot; for a spa-like feel, go heavier.
