Key Feature 1: Advanced Insulating Yarn

Description: Crafted with high‑performance insulating yarn and a soft brushed inner that traps more warm air close to the skin. Delivers a dependable 0.45 tog rating for impressive warmth while staying lightweight and easy to layer.

Benefits: Reliable, all‑day thermal regulation keeps her warm without added bulk, so she can layer under clothes comfortably in changing winter conditions.

Description: Ribbed fabric contours to the body for a snug yet flexible fit. Smart, side seam‑free construction minimises friction for irritation‑free comfort during active play and everyday wear.

Benefits: Stays put, stretches with movement, and feels smooth against the skin—ideal for school days, sports, and weekend layering.

Key Feature 3: Cotton-Rich Fabric
