Chris Townsend reviews an exceptionally breathable lightweight waterproof.

This review is part of our lightweight waterproofs gear guide, and was first published in the May 2019 issue of The Great Outdoors.

This was originally supplied for a four- season jacket review. I said then I liked it but didn’t think it was suited to full winter conditions. But for three-season use it’s excellent. The AscentShell fabric is one of the most breathable reviewed. You really have to work hard to get condensation in this jacket. It stretches too – which is handy as the Medium is only just big enough for me over a light fleece jacket. The fabric is soft and comfy too.

An excellent adjustable hood gives great protection and moves with the head. It’s helmet-compatible and can be cinched down. Its zip pullers are inside the jacket. However, the cordlocks are outside and I used these to adjust the fit.

The pockets are quite roomy. The lower ones are map-sized but cut off by a hipbelt. The chest one is only big enough for a GPS or phone. All pocket bags are mesh so the pockets can be left open for airflow into the jacket. The cuffs also allow some ventilation but could be a bit wider.

The Interstellar is quite expensive but the breathability is exceptional.
