A reliable pair of girls' sports leggings from a brand that knows performance kit. The North Face Girls Flex Leggings in Black are designed for active wear — whether that's PE, after-school sport, hiking, or just everyday movement. The Flex name signals what matters most here: stretch and ease of movement, without the leggings losing their shape through the day.
In plain black, these are as practical as leggings get. They work with almost any top, layer easily under a jacket or gilet in colder weather, and don't look out of place worn casually outside of sport. For girls aged 6 to 20 years, this is the kind of activewear staple that earns its place in the wardrobe by being genuinely useful across multiple activities.
Made in Cambodia as part of The North Face's AW2026 activewear collection, these designer girls' sports leggings are built to a higher standard of construction than standard high-street alternatives — with better stretch retention and durability over repeated washes.

Buying Advice
- Fit: The North Face girls' leggings are cut for an active, close fit. If your daughter prefers a more relaxed feel or is between sizes, size up. The 14–16 and 18–20 year sizes work well for older girls and teens who want a longer leg length.
- Layering: These work well under a longer top or hoodie for casual wear, or paired with a The North Face fleece or jacket for outdoor activities in cooler weather. The stretch fabric sits flat under base layers without bunching.
- Versatility: Black is the most practical choice for school PE kits, sports clubs, and everyday wear. It doesn't fade as visibly as coloured leggings and pairs with any top colour.
- Care: Machine wash on a cool or warm gentle cycle. Avoid fabric softener, which can break down the stretch fibres over time. Line dry or tumble dry on low — do not iron.
