Why Supima

Supima® (short for Superior Pima) is among the rarest cottons in the world. Grown only in the United States, on about 500 family farms across four states, it accounts for less than 1% of global cotton production. Its extra-long staple fibers spin into a finer yarn, up to 45% stronger than regular cotton, creating a fabric that is exceptionally soft, resists pilling, and grows softer with every wash. It is what UpsideLuxe is made from.

“The fabric is incredibly soft and cool to the touch, which is perfect for me since I tend to sleep hot.” — Kate (received a sleep sack to try)

Materials

• 100% Supima cotton, woven into a 400-thread-count sateen for a smooth, refined hand feel
• Finished in Egret, a soft, luminous cream chosen for its clarity and quiet distinction; calm and understated, yet visually present on the bed
• Naturally temperature-regulating, comfortable in both warm and cool sleeping environments

Dimensions and Fit

• Overall dimensions: 45" wide × 90" long
• Generously sized for adults, designed for unrestricted movement throughout the night
• Drapes smoothly without excess bulk

“It is plenty long. I am 6 feet tall and didn’t feel crowded.” — Erika (received a sleep sack to try)

Care Instructions

• Machine wash cold with like colors
• Gentle cycle recommended

“I was happy to find out that when washing it didn’t change or compromise the quality of the sleep sack.” — Lara (received a sleep sack to try)

Craft and Sourcing

I designed every detail of the UpsideLuxe Sleep Sack myself, here in Albuquerque, New Mexico. Each one is woven and sewn from American Supima cotton by a fine textile mill in Tamil Nadu, India, in small production runs, and every run is independently inspected before it ships.
