Quick Summary
The Mountain Warehouse Lightning 3-in-1 Kids Rain Jacket is a navy children's rain jacket in size 9-10 years. It is described as waterproof with taped seams, a detachable hood and stretch cuffs, so the main buying checks are the size, the jacket format and the stated weather protection features.
For a child's coat, the most important check is fit. Confirm the size is right for the wearer and check whether the jacket format suits how it will be worn over other layers.

What to Compare Before Buying
- Size: This version is marked 9-10 years. Compare that with the child's current size and the room needed for layers underneath.
- Weather protection: The jacket has a 2,000 mm waterproof rating and taped seams. Compare that with the level of rain exposure you expect.
- Hood setup: The hood is detachable, so check whether a removable hood suits the intended use.
- Sleeve fit: Stretch cuffs affect the wrist finish, so check whether that style works for the wearer.
Choosing the Correct Version
The navy colour and 9-10 years size are the main variant details here. Check both before selecting an offer, especially if you are comparing this jacket with another colour or size in the same range.
Before You Decide
Confirm the 9-10 years size, the navy colour and the 3-in-1 jacket format before choosing an offer. If waterproof rating, detachable hood or taped seams matter to your decision, compare those details with the child's needs and intended use.
