What to Compare Before Buying
- Size: The stated size is 7-8y, so check it against the child’s current fit and any layering you expect.
- Wearing options: This is a 3 in 1 jacket, so compare whether you want the shell, the inner jacket or both together.
- Wet weather use: The jacket is stated at 2,000 mm waterproof, so compare that rating with the level of rain protection you need.
- Details that affect use: A detachable hood, taped seams and zipped pockets may matter if those features are important to you.
Before You Decide
Confirm the 7-8y size and the Blue (01) colour before choosing an offer. Check whether you want the 3 in 1 format, since the jacket is built around an outer shell and an inner lightweight layer. If waterproof rating matters, compare the stated 2,000 mm figure with your needs and follow the care guidance for the garment.
