IHM-32-BLK - Alpaca Lined Whipcord N1 Deck Jacket - Superblack

Apart from using wax, a spray based water repellent appropriate for cotton fabric would be fine. On lighter coloured iterations it may darken the fabric.

That being said, the IH N-1’s perform very well in wet weather in my experience, despite being cotton. I wouldn’t wear it out in a torrential downpour or on a long wet day out, but as a winter coat around town it works. It doesn’t seem to absorb water easily. Rain has a tendency to bead and run off. I think it has to do with the tightness of the weave.

@Giles:

Awesome! It looks like that really requires some skills though, aka the potential for damage is real

Giles

The worse that can happen is you get a bit too much wax in one area…..But personally, I would not bother, if I wanted full breathable/waterproof, I'd wear one of our technical jackets...

Years ago I once tried this method with my IHM-04, mentioned by @tmg and @Aetas:

It's an easy job to spray the mixture on the wet jacket and to rub away some white residuals with a wet rag when the jacket is nearly dry. But honestly I don't remember if the jacket has been way more water repellent after that treatment (for a longer time).

I will follow Giles' excellent advice. Luckily, I already own the IH mountain parka.

You are very good to go then…..

How does the warmth of these compare to the previous 100% alpaca lining versions?

They are the same as the other N-1 jackets. The design has only changed superficially down the years.

Giles

We used to incorrectly describe the lining as Alpaca when in fact it was an Alpaca/wool mix. That was a lost in translation cock-up. The lining is the same as it always has been….
