Why hikers trust Cortazu
Don't take our word for it.
Tested in real rain and wind. Rated 4.8/5 by our customers. Here's what that looks like.
Time for a new shell?
Replace your old shell with a field-tested one.
Most hikers start looking when their old jacket gives up: it wets out, or it's simply worn through. Make the switch to a shell tested on the trail, in real weather, without paying extra for a big-brand logo.
- Waterproofing and fit first, because hikers told us that's what matters most
- Field-tested in rain, wind and on long days out
- 3-year warranty, plus repairs if it needs one
You're not the first
Less doubt. More trail.
Trying a brand you don't know yet feels like a risk, especially when you can't try the jacket on first. Thousands of hikers took that step before you, and we make it easy to get it right.

A few useful answers.
Which jacket to choose, how to find your size, and how you know it keeps you dry.
Alpine, Delta INS, or Aero: which jacket is right for me?
Alpine, Delta INS, or Aero: which jacket is right for me?
It depends on how you keep warm and how much you carry. Alpine is an uninsulated shell for layering: wear it over a base layer and add a fleece when it gets cold. Delta INS has insulation built in for cold days, winter walks, and travel. Aero is the lightest of the three at 300 g, and it packs into its own pocket for days when rain might come. Still not sure? The Product Finder matches you to a jacket in six questions.
What size should I order, and what if it doesn't fit?
What size should I order, and what if it doesn't fit?
Every product page shows the model's height and the size they wear, so you can compare against your own height. All our jackets are a regular fit with room to layer underneath. If it doesn't feel right, you have 21 days to return or exchange it in the EU. Or try it on first in our Amsterdam store at Bilderdijkstraat 136H.
How do I know it will keep me dry?
How do I know it will keep me dry?
Our shells use Barrier CT, a waterproof-breathable fabric we develop ourselves with specialist suppliers. We have it tested by an independent lab for waterproofing, breathability, and abrasion, and we publish the full results so you can check them yourself.
Why is Cortazu cheaper than the big outdoor brands?
Why is Cortazu cheaper than the big outdoor brands?
We sell mainly direct, and we don't pay a licence fee for a branded membrane. That leaves out a large part of what usually goes into the price of a technical jacket. What you pay for is the jacket itself, backed by a 3-year warranty and a repair service if it ever needs one.
