Quick answer

Wash your Pima cotton pajama set in cold water on a gentle cycle, then hang it to dry. Skip the dryer entirely—heat is what breaks down the fibers and causes shrinkage and pilling.

Why Pima cotton needs a gentler routine than everyday cotton

Pima cotton has longer fibers than standard cotton, which is why it feels smoother and resists pilling. That advantage disappears if you treat the fabric like a basic tee. Hot water and tumble drying rough up the surface and shrink the fibers, so the set that felt silky on day one can turn stiff and fuzzy after a few washes.

The good news: you do not need special detergent or a separate laundry day. A cold wash and a drying rack are enough. The only real adjustment is patience while it air-dries.

What to check before you wash

Always read the care label on your specific set first—it is the final word on temperature and drying. For the Pima Lusso Printed Long Sleeve Top & Boxer Pajama Set, the label calls for cold water wash and hang to dry, and explicitly says not to dry in the dryer.

If your set has satin piping, turn it inside out before washing to reduce friction on the trim. Skip fabric softener and dryer sheets; they coat the fibers and can make the cotton feel less breathable over time.

Step-by-step Pima cotton pajama care

  1. 1. Read the care label first: Check the tag on your specific set before doing anything else. Follow its temperature and drying instructions exactly, since blends and trims can vary. If the label says cold wash and hang dry, treat that as your default for every wash.
  2. 2. Turn the set inside out: Turn the top and boxer shorts inside out before washing. This reduces surface friction that can dull the fabric and protects any satin piping from snagging. Fasten any buttons and close the fly to keep the shape from twisting in the wash.
  3. 3. Wash in cold water on a gentle cycle: Use cold water and a gentle or delicate cycle with a mild detergent. Avoid hot water, bleach, and fabric softener—they break down fibers and leave a coating that reduces breathability. Wash separately from heavy items like jeans or towels to limit abrasion.
  4. 4. Skip the dryer completely: Do not put the set in the dryer. Heat causes shrinkage and pilling, and it can damage the smooth finish of Pima cotton. Instead, gently reshape the pieces and hang them to dry. Hang drying takes longer but is the single most important step for longevity.
  5. 5. Store folded, not on a hanger: Once dry, fold the top and boxers and store them flat in a drawer. Hanging a long sleeve top can stretch the shoulders over time. Keep the set away from rough hooks or zippers in the drawer to avoid snags.
