I just picked mine up instore in Cardiff. Lots of sizes left. You will need the Go Outdoors discount card (£4), but as I already had one, I thought that this was a good deal. I know that there is a post for the jacket at £37, but seemed that offer seem to be limited in size and colour, wheras different colours are available at instore....I got a black jacket myself.
The Berghaus RG1 Jacket is one of Berghaus' best selling waterproofs, keeping people dry on more and more British hills and streets.
The RG1 (and the ladies' version, the Calisto Jacket) is a versatile jacket you can wear anywhere, with a hardwearing nylon rip-stop outer layer.
It's nice and light for it's level of protection, weighing in at an excellent 540g.
The RG1 Jacket has a DWR (Durable Water Repellent Treatment) applied to the fabric which is made from Berghaus own Aqua-Foil technical material.
