FIEMOL Baby Swaddle Sleep Sack 3-6 Months | 2-Pack Blue Whale

Meet the FIEMOL Baby Swaddle Sleep Sack

Designed for babies around 3 to 6 months, the FIEMOL Baby Swaddle Sleep Sack is a versatile, two-pack wearable blanket that grows with your little one. It combines a swaddle blanket and a sleeping bag in a single, detachable system, giving families adaptable warmth and comfort from naps to night sleep. The cheerful blue whale design adds a playful touch to bedtime, while the soft, breathable fabric keeps baby cozy without overheating.

Flexible 3-in-1 Design That Grows With Baby

• Detachable swaddle wings pair with other sleeping bags to tailor warmth for different seasons and growth stages.
• Swaddle mode at night provides a snug wrap to help ease the startle reflex and promote calm moments before sleep.
• Sleeping bag mode offers more freedom of movement while keeping arms and torso secure.
• Swaddle-only mode delivers a lightweight option when the weather is warmer or when less wrapping is desired.

Quiet Closures for Undisturbed Sleep

• Silent, gentle hook-and-loop closures are soft on baby’s skin and designed to reduce nighttime disturbance.
• The 2-way zipper opens from the bottom for quick diaper changes with minimal movement of your baby.

Breathable Comfort You Can Feel

The FIEMOL swaddle sack uses breathable cotton that feels cloud-soft against tiny skin. It’s lightweight enough to be comfortable on warm days and provides a cozy wrap when temperatures drop. The fabric is moisture-wicking to help baby stay comfortable through naps and nights, while the TOG system lets you adjust from a light 0.5 TOG on warmer days to a snug 1.0 TOG for cooler evenings. Wrapping the wings is like tucking in a light blanket — a simple cue for baby that they’re tucked in and safe.

• Breathable cotton keeps baby comfy without overheating.
• Moisture-wicking fabric helps maintain a fresh feel through day naps and night sleep.
• Seasonal adjustability with TOG options, adapting to changing room temperatures.

All-in-One Convenience: 2-Pack in a Sweet Blue Whale Design

The 2-pack gives you reliable options for busy parents: rotate between outfits, or have one ready for quick trips or overnight stays. The blue whale pattern adds a friendly, soothing look that complements bedtime routines while staying practical for everyday use.

Simple How-To

Place your baby on their back, secure the wings for a gentle swaddle if needed, zip up from the bottom, and switch to the sleeping bag mode as your baby grows. When temperatures change, detach or reattach the wings to match seasonal needs. This design supports a calm, comfortable transition between sleep stages without requiring a full wardrobe change.
