Summer nights are short and warm. What you wear to bed should help you stay cool — not trap heat against your skin.
The Best Summer Sleepwear Fabrics
Modal (Best): Fifty percent more absorbent than cotton. Wicks moisture away from your skin. Cool to the touch. The fabric equivalent of the cold side of the pillow.
Silk: Temperature-regulating. Light enough for summer, substantial enough to drape beautifully.
Lightweight cotton: Breathable but absorbs moisture and can stay damp. Fine for moderate heat, less ideal for heatwaves.
Avoid: Polyester. Satin blends with synthetic backing. Anything that feels plasticky.
The Summer Sleep Capsule
Two modal camisole and shorts sets. One lightweight silk slip dress. That is it. Rotate between them. Wash on cool. Air dry in the sun. The modal will get softer every wash. The silk will keep you cool on the hottest nights.
