hard to find Barbour Beresford waist-length jacket, in washable waterproof fabric.   this has been used but is in good condition, has a few small marks but these will almost certainly wash out.  I've never washed it and had it since new.   Really versatile summer jacket, cord collar and cuff lining, adjustable cuffs, really useful net pockets in the lining, every easy to wear.   It's a medium but as is normal with Barbour they run big.  I wear a 44 chest normally and it fits me neatly and comfortably.   A 42 inch chest will be the perfect size for this jacket.
