What waterproof rating should I look for in a women's jacket for UK rain?

Around 5,000mm can handle lighter everyday showers, approximately 10,000mm is a sensible target for regular walking and sustained rain, and 20,000mm or more adds margin for prolonged severe exposure. Ratings only describe the fabric; taped seams, zip protection and hood fit are equally important.

Why can a waterproof jacket feel wet inside even when it is not leaking?

Perspiration can condense faster than the fabric releases it, especially during uphill walking or when the outer face wets out. Open pit zips or pockets designed for ventilation, reduce insulation and slow the pace before assuming failure. A breathable shell still needs temperature and moisture management.

Should a women's waterproof jacket be hip-length or longer?

Hip-length shells give freer movement, work better with rucksack belts and suit active walking. Longer jackets protect the thighs and smart clothing during commuting, school runs and dog walks. A two-way zip or rear vent helps a long coat remain comfortable when sitting or climbing.

Are taped seams necessary on a waterproof jacket?

Yes for reliable sustained rain protection. Needle holes from stitching can admit water even when the fabric itself is waterproof, so seam tape seals those routes. A jacket described only as water resistant may omit full taping; check whether all seams or only critical seams are sealed.

What should I wear underneath a waterproof shell in winter?

Use a moisture-managing base layer and add a fleece or insulated mid-layer according to temperature. The waterproof supplies weather protection, not necessarily warmth. Leave enough room for the insulation to loft without making the shell so large that the hood and cuffs cannot seal.
