Clek - Fllo Convertible Car Seat - Mammoth Ziip (Merino Wool & TENCEL)

The Compact Convertible Car Seat.

The Clek Fllo is one of the safest narrow convertible car seats available, supporting extended rear-facing use and allowing most kids to remain rear-facing until their fourth birthday. The Mammoth Ziip features a premium Merino Wool & TENCEL blend for exceptional softness, breathability, and natural temperature regulation.

Safety Built Into Every Inch

The Fllo is engineered around Clek's EACT (Energy Absorbing Crumple Technology), which actively reduces collision forces using automotive-inspired crumple technology. A Steel Anti-Rebound Bar enhances rear-facing safety, protects against head impact, enables a snug installation, and adds 1–2" of extra legroom for rear-facing children. The adjustable structural headrest features deep side wings, energy-absorbing foam layers, and a complete metal substructure for advanced side impact protection. The Mammoth Ziip is free of brominated and chlorinated flame retardants and meets or exceeds FMVSS213.

Comfort & Convenience

Day-to-day use is equally well considered. The removable seat cushion provides easy rear-facing belt path access without uninstalling the seat, and built-in lock-offs tension and remove excess belt slack. A No-Twist Harness with buckle stowage simplifies buckling, while 6 harness heights and an adjustable crotch strap accommodate a wide range of sizes. The Ziip Away Cover removes for easy cleaning, and the seat is FAA approved for aircraft use. Clek backs it with a lifetime extended warranty and a 9-year expiration date — and offers recycling through their program. Made in Canada using domestic and imported components.

Fabric & Certifications

The Mammoth Ziip is crafted from a premium Merino Wool & TENCEL blend — naturally soft, hypoallergenic, and temperature-regulating. The Merino Wool is ethically sourced and non-mulesed. The fabric is PFOA-free, PFOS-free, PFC-free, and PFAS-free, fluorine-free, and OEKO-TEX® Standard 100 Certified — one of the most rigorous independent textile safety standards available.
