Stay Dry When the Weather Turns Fast
Hydro Shield is the lightweight waterproof jacket made for sudden showers, windy commutes and everyday wear — with a 10,000mm waterproof rating, sealed seams, a windproof shell, 20,000+ breathability, and a 400g packable build.
One minute the sky is clear, the next you are walking into wind and rain. Hydro Shield is built for that kind of day — a lightweight shell you can keep close, throw on fast, and wear without the bulk of a heavier winter jacket.
With a 10,000mm waterproof rating, sealed seams, and a windproof shell, Hydro Shield is designed for everyday rain, wet commutes, travel, and weekend wear. The 20,000+ breathability helps heat and moisture move out while you keep moving, and the 400g packable weight means it disappears easily into a backpack, tote, or carry-on until you need it.
Then the practical details do the rest: a detachable, adjustable hood when conditions change, adjustable cuffs to help seal out wind, and waterproof pockets for the essentials you do not want exposed. With free shipping across Canada and a 30-day money-back guarantee, Hydro Shield is easy to try and even easier to keep within reach.

Hydro Shield uses a 10,000mm waterproof rating with sealed seams, which is strong for everyday rain, commuting, travel, and general outdoor use. For prolonged extreme conditions, treat it as part of a layering system rather than an expedition shell.
Yes. At 400g, Hydro Shield is designed to pack down small enough to keep in a day bag, work tote, or suitcase without taking over the space.
