no idea what it’s like in the rain

It’s shower-proof as it’s just pertex microlight fabric. They are a great bit of kit, windproof, breathable and very quick drying.

Are these the same fabric as the Dyno?

No

no the Dyno uses Pertex Equilibrium (same as Rab Vapour Rise)
This is a useful resource:

In simple terms the Dyno is slightly tougher and more breathable but not as windproof or as light.

There are some stats on the web with the results of the lab test for windproofness, insulation etc. The US site Backpacklight has all manner of geeky info on there

Mine is about as waterproof as blotting paper, but its great as a layer to be put on when an evening ride starts to get chilly.

Great bit of kit, but no real water resistance

If you wash it with a re-proofer like Nikwax or Graingers you can significantly enhance it’s water-resistance – but it’s nothing like a proper waterproof.

Think cling film and you wont be far off

It is a windproof not a waterproof!!
Fantastic bit of technical clothing if you know what it’s for.

Its nowt like cling film.

Oh, I was hoping it would be a breathable version of my Aldi boil in the bag packamac.

Feels a bit like clingfilm, but is very breathable, and packable. Unlike bulkier windproofs, rain goes pretty much straight through though.

Brilliant bit of kit, I use mine over a thicker merino top in autumny type weather. Packs to nothing as well.

Got a gilet made of the same that is better still.
