I have an unused Mountain equipment mens's arete hooded down jacket, in size medium (cosmos colour) available. Bought earlier this summer in a sale for £99 to replace a warmer and more aged model (also for sale, see other post), but in the intervening time I've lost more weight and the medium is too big for me now. Which is good news for my health at least, if not my wallet!
It's totally unused, never left the wardrobe, and if it still had tags on it and was able to be returned I would do so. See these generally selling for 125-130, but as I paid only £99 for it I'm hoping to pass on a good deal to someone else.
