How does it prevent my baby from overheating?

Our specially engineered organic cotton actively wicks moisture away from your baby's skin while allowing air to circulate freely.

This prevents the dangerous heat buildup that many parents describe as finding their baby "like a furnace" at night.

Is it baby safe?

Absolutely.
The Summer Sleep Sack has a safety-first design that significantly reduces the risk of suffocation, rashes, and SIDS.

Does it help reduce SIDS risk?

 While no product can completely prevent SIDS, our sleep clothes address a major risk factor by preventing overheating. Research published in Frontiers in Pediatrics and by the NIH shows that "excessive thermal insulation can lead to lethal hyperthermia" in infants. By maintaining optimal temperature, our product helps reduce this specific risk factor.

Is it actually "breathable"?

Our organic cotton uses a specialized weave that creates genuine micro-ventilation to help your llitle one sleep comfortably all night long.

What should my baby wear underneath?

It depends.

  • For temperatures above 75°F: just a diaper or thin onesie
  • For 70-75°F: short-sleeve bodysuit
  • For 65-70°F: long-sleeve bodysuit
  • Below 65°F: footed pajamas

How do I wash it?

Unlike some delicate organic products, there's no need for special detergents or hand washing.

    Cold baby cries, hot baby dies

    That old saying kept me checking my LO constantly. But, with the Summer Sleep Sack he no longer gets sweaty on summer nights & sleeps a lot more now.
    Literal godsend.

    She Sleeps Perfectly

    We live in Perth where it regularly hits 30'C+ , and even with our struggling AC, my daughter stays perfectly cool in her little sack.

    Wriggle-Proof

    We have a very active sleeper who rolls constantly. But with this sack, she legit for the first time, she doesn't try to wiggle out at night!

    Bubs Sleeps Better Now

    The temperature difference between bubs' skin in regular sleep clothes versus the Summer Sleep Sack is crazy! My little one seems to cry less at night now.

    Long-Lasting

    I was worried the organic fabric wouldn't hold up to frequent washing, but we're six months in and its still silky-smooth.
