| Protection | Fully waterproof & windproof |
| Tech | Membrane (e.g. Gore-Tex), taped seams |
| Trade-off | Less breathable & stretchy |
| Best for | Storms, alpine, wet weather |
A hardshell is a fully waterproof, windproof outer jacket built to keep rain and snow out in serious weather, typically using a membrane like Gore-Tex with taped seams. Hardshells are tough and protective but less breathable and stretchy than softshells, making them the go-to for storms, alpine climbing, and wet conditions.
How it works
A waterproof-breathable membrane like Gore-Tex plus taped seams seals out weather — the most protective shell.

Frequently asked questions
What is a hardshell jacket?
A hardshell is a fully waterproof and windproof outer jacket, usually built around a waterproof-breathable membrane such as Gore-Tex with taped seams to seal out rain and snow. It's the most protective shell for sustained bad weather, prioritizing weatherproofing over breathability.
Hardshell vs softshell?
A hardshell is fully waterproof but stiffer and less breathable; a softshell is breathable and stretchy, blocking wind and light moisture but not heavy rain. Choose a hardshell for storms and wet conditions, a softshell for active use in dry or variable weather.
What's the difference between a hardshell and a rain jacket?
They overlap heavily — both are waterproof shells. 'Rain jacket' often implies a lighter, simpler waterproof for general use, while 'hardshell' usually means a more durable, feature-rich jacket built for mountaineering and storms. All hardshells are rain jackets, but not all rain jackets are burly hardshells.
