What to Compare Before Buying

  • Size: this version is labelled 3-4 years. Check the fit against the child’s measurements and intended layers.
  • Rain protection: the stated DWR treatment is for light rain or limited exposure. Check the exact version’s specification if it will be used in more sustained rain.
  • Configuration: confirm that the selected version includes both the detachable inner jacket and outer layer.

Who This Product May Suit

The two separate layers can be worn in different combinations. The stated water-repellent treatment is intended for light rain or limited exposure; it does not establish protection for prolonged wet conditions.

What Is Included

The described 3-in-1 configuration comprises an outer layer and a detachable inner jacket. Check the selected version’s contents before choosing it.

Before You Decide

Check the Fell model, navy colour and 3-4 years size, and confirm that the selected version has both layers. Consider whether the stated light-rain use matches the conditions it will face.
