Cheap gear is often not worth buying. However, there is the occasional gem. My Adidas coat has been a constant companion on the mountains for nearly 10 years. At under £20 it was warm, waterproof, windproof - and light too. Sadly the zip failed after Black Hill so it was consigned to the bin - owing nothing.
I bought it at our local TJ Hughes so I wandered in to see what they have nowadays. I picked up a good Regatta fleece for £6.99 and a well made Regatta waterproof padded jacket for £19.99 - far more technical than my Adidas - but will it last?
