Key Details

Detail Product information and buyer relevance
Model Cannonball, model 023266203010.

Configuration Described as a 3-in-1 jacket: waterproof outer shell, lightweight inner jacket, or both worn together.

Key Features Explained

The two jacket layers can be worn separately or together, giving a choice of configurations. The listing describes the outer as waterproof and gives it a 2,000 mm rating; taped seams are also specified. These details do not establish performance in every type or duration of wet weather.

The hood is detachable, and the pockets have zipped closures. Check that these features suit the intended use and that the hood is attached or removed as preferred.

What to Compare Before Buying

  • Size: confirm the selected size is 13 Years, then consider the intended fit and room for clothing layers.
  • Colour: check that the selected version is Dark Khaki (01).
  • Wet-weather requirements: compare the stated 2,000 mm rating with the conditions the jacket needs to handle; do not treat the rating as a guarantee for all conditions.

What Is Included

The 3-in-1 configuration is described as an outer waterproof shell and a lightweight inner jacket. The listing does not clarify whether the detachable hood is removable from the outer layer or another component, so check the selected configuration if this detail matters.

Planning Layers for a Walk

Before heading out, decide whether the outer shell, inner jacket or both are the intended configuration. Check the fit with the clothing likely to be worn underneath, and confirm that the hood is in the preferred position. Weather and activity can change, so consider whether the chosen layers suit the conditions rather than relying on the waterproof rating alone.

Before You Decide

Confirm the 13 Years size, Dark Khaki colour and the 3-in-1 configuration. Also consider whether the stated 2,000 mm waterproof rating meets the needs of the intended use.
