Compare the fleece and cotton versions of the Flying Squirrel Pajama for winter sleep. Learn which fabric keeps your toddler cozy and which is better for milder nights.

Quick answer

For cold winter nights, the fleece Flying Squirrel Pajama provides extra warmth like a wearable blanket, while the cotton version is better for milder rooms or year-round use.

Why fabric choice matters for winter sleep

Toddlers move a lot during sleep, and a sleep sack that doubles as a wearable blanket keeps them covered no matter how much they toss. The main difference between the fleece and cotton Flying Squirrel Pajama is warmth. Fleece traps more heat, while cotton breathes more easily. Your room temperature and your child's sleep habits will determine which one helps them sleep comfortably through the night.

Fleece vs. cotton: trade-offs at a glance

  • Fleece version: Acts as a wearable blanket. Best for cold rooms (below 68°F/20°C). The fleece layer adds noticeable warmth without extra layers underneath. Use when your toddler's room is drafty or you live in a region with freezing winters.
  • Cotton version: Breathable with gentle stretch. Better for rooms kept at 68–72°F (20–22°C) or for children who tend to sweat in fleece. Still provides coverage without overheating. Choose for milder winter climates or if your child runs warm at night.
  • Both share AAP-safe design: Both versions have a loose fit, ribbed cuffs, and are designed based on AAP safe sleep guidelines. Neither restricts movement or poses a suffocation risk. Safety is identical; only warmth and breathability differ.
