⚡ At a Glance
- • Wearing Comfort: Lightweight microfleece inner traps warmth close to the body while allowing free movement
- • Best for: Active children and families needing a versatile coat for school runs and wet-weather walks
- • Not ideal for: Prolonged heavy downpours or technical mountaineering where higher waterproof ratings are required
A three-way system pairs a waterproof outer shell with a lightweight microfleece inner. Taped seams and a 2,000mm waterproof rating aim to keep water out.
Dependable dryness - with taped seams and 2,000mm waterproof rating
Waterproof tape runs across all stitched areas to seal joins, and the outer shell has been tested to 2,000mm hydrostatic head. Sealed seams reduce the common entry points for moisture in wet conditions.
Keeps children dry during typical wet weather and showers, suitable for school runs and family walks.
Warmth without bulk - with a lightweight microfleece inner
Microfleece acts as a low-weight insulating layer that traps warm air close to the body while remaining breathable. The inner jacket is intended as a standalone layer or to be zipped into the shell.
Provides comfortable insulation on chillier days without restricting movement, so layering remains practical.
Built to last through play - with Rip Stop fabric and anti-pill finish
Rip Stop weave limits tear propagation by reinforcing the fabric with a grid pattern, while anti-pill treatment reduces bobbling from abrasion. Both elements extend the usable life of the outer material.
Stands up to playground scuffs and repeated use, helping the coat retain its appearance over time.
