Organic Winter Long Sleeved Sleep Onesie - Dragonflies 3.5 TOG

Sleep Onesie – 2.5 TOG Organic Cotton

Sleeping Bag Alternative | Organic | TOG-Rated

Includes a FREE Room Thermometer

Every Sleep Onesie includes a FREE room thermometer, helping parents confidently dress their child for safe, comfortable sleep.

A Flexible Sleeping Bag Alternative

The Sleep Onesie is a TOG-rated alternative to a traditional sleeping bag, designed to be worn on its own or layered with PJs or Bodywear underneath. It’s ideal for:

• Toddlers and preschoolers transitioning to a big bed
• Sleep walkers
• Children who kick off blankets
• Little starfish who dislike the restriction of sleeping bags

Warm, 2.5 TOG Comfort

The 2.5 TOG Sleep Onesie is suitable for room temperatures of 17–21°C (63–70°F), keeping children warm without the need for loose blankets when used in a cot.

For older toddlers and preschoolers who are blanket-training in a big bed, the TOG rating helps maintain warmth if blankets are kicked off. If using a 2.5 TOG or 3.5 TOG for blanket training, a light blanket on top is recommended to prevent overheating.

Use the included room thermometer and What to Wear Guide to layer appropriately underneath. Socks can be added on colder nights for extra warmth.

Organic, Stretchy & Skin-Friendly

Made from and filled with GOTS-certified organic cotton, the Sleep Onesie is breathable, non-toxic, and gentle on sensitive or irritable skin. The super-stretchy fabric allows freedom of movement while keeping your child cosy throughout the night.

Designed for Comfort & Practicality

• Separate legs — supports natural movement and walking.
• Three-way zip — easy overnight nappy changes or toilet trips.
• Fold-over foot cuffs — keep little toes warm.
• 1.0 TOG sleeves — balanced warmth for arms.
• Zip enclosure — protects delicate skin.

Certified & Safety Approved

The Sleep Onesie complies with AU, US, UK, and EU safety and quality standards and is reviewed by the Eczema Association of Australasia as a skin-friendly product. All fabrics are dyed using non-toxic, water-based dyes, with prints designed in-house.
