Cozy warmth for cold-room nights

The Nivolltha 3.5 TOG sleep sack with feet in foliage brings thoughtful warmth to chilly evenings. Designed for toddlers who stay active, this wearable blanket uses a soft 100% organic cotton exterior with a plush quilted polyester filling. The color and texture feel inviting against little skin, while the overall construction aims to keep your child warm without excess bulk.

Smart design that grows with your child

With a 3.5 TOG rating, this sleep sack is well-suited for rooms below 12°C (54°F). The sleeves are detachable and can be zipped on for full coverage or removed to reveal arms, allowing your child to move freely during crawls, steps, or playful kicks. The feet-and-leg design provides a roomy, natural stance that supports active leg movements while preserving warmth.

• Plush, breathable exterior made from organic cotton for skin-friendly softness.
• Legs and feet offer mobility and a relaxed hip position for growing toddlers.

Designed with parents in mind

Practical details are built to simplify nighttime routines. Bottom crotch snaps enable quick diaper changes without fully exposing warmth, and the 2-way zipper makes dressing convenient from the top or bottom. A zipper guard protects delicate skin, while the shaped neckline and snug cuffs help keep the garment in place through various night-time activities.

• Secure chest area creates a calm, swaddle-like feel for better sleep transitions.
• Snug cuffs at wrists and ankles prevent riding up and maintain warmth throughout the night.
