Here is the clinical reality: an immature neurological system cannot effectively regulate core body temperature. Putting your baby in a synthetic polyester fleece traps ambient heat, forcing them into a dangerous "cold sweat" loop. They overheat, sweat, and wake up crying because they are damp and shivering. If you are battling false starts and warm summer nurseries, our collection of bamboo sleep sacks eliminates the guesswork. Engineered specifically for hot rooms (74–78°F), this 0.5 TOG sleep sack delivers the necessary tactile security of a baby sleeping bag while strictly preventing thermal failure.
