The Lacoste Baby Tech Fleece Tracksuit in Navy is a two-piece tracksuit set for babies aged 6 months to 24 months, made from 100% polyester tech fleece in Vietnam. It is listed as unisex and sits in the Loungewear collection at Childsplay Clothing — a practical, everyday outfit for the cooler months that works as indoor loungewear, a layering piece under outerwear, and a casual outfit for visits and outings.

Tech fleece is a smooth-faced polyester fleece — distinct from the plush, pile-surface sherpa used in the baby romper range. Where sherpa has a textured, soft pile that reads as cosy and tactile, tech fleece has a flat, smooth face that is lighter, less bulky, and easier to layer under a pramsuit or outer jacket without adding significant volume. The warmth-to-weight ratio is the key practical advantage: tech fleece provides meaningful insulation for a baby without the bulk that makes car seat straps and carrier harnesses difficult to fit correctly. The two-piece format — a separate top and matching bottoms — is more practical than a one-piece at the 6–24 month stage, when babies are beginning to move more independently and nappy changes are easier with separates. The plain navy colourway is unisex, coordinates with almost any combination of inner layers and outerwear, and holds its appearance through the frequent washing that baby clothing requires. This is a designer baby tracksuit that functions as a genuine everyday wardrobe anchor for the first two years.

Buying Advice

• Layering: The tech fleece tracksuit is designed to be worn as a mid-layer — over a cotton bodysuit or vest underneath, and beneath a pramsuit or outer jacket for outdoor use in cold weather. The smooth face of the tech fleece means it slides easily under an outer layer without bunching or adding bulk at the shoulders and arms.
• Two-piece vs one-piece at this age: From around 6 months, when babies begin to roll and move more actively, a two-piece tracksuit becomes more practical than a one-piece romper for nappy changes — the bottoms can be removed independently without undressing the baby entirely. The separate top also allows for more flexibility if the baby has a growth spurt that affects the top and bottom differently.
• Care: Machine wash at 30°C on a gentle cycle. Avoid fabric softener, which can reduce the fleece’s insulating properties over time by coating the fibres. Tumble dry on low or lay flat to dry. Do not iron directly on the fabric. Wash with similar dark colours to maintain the navy tone.
