It's the heaviest weight thornproof cloth that Barbour use; on the outside there are 2 large bellows pockets, each closed by a pair of brass studs/poppers, and 2 hand warmer pockets at chest level. The collar is corduroy lined, with studs underneath to attach an optional matching hood, in the same heavyweight material.
Inside, there's a velcro closure wallet pocket one side, and a zip up map/hipflask pocket on the other, each about chest level. Lower down, on each side there's a large poacher pocket with a removable, washable nylon liner. The whole inside is lined in the usual Barbour tartan wool, although it's a different pattern to that in the lighter Barbours.
Front closure is by a 2 way brass zip that, with the collar up, will reach chin level, plus a storm flap with brass press studs. Inside there are also press studs to attach an optional fleece liner/waistcoat.
So what's it like in use? First up, it's bloody heavy, so not much cop for forced marching in. However, when the weather turns shitty, there's nothing better.
Windproof, very. Waterproof? Among other trips, I once wore it on a sea fishing trip in the North Sea, 30 foot waves crashing over the charter boat, everyone else pissed wet through, while inside this coat I was dry and warm.
It's seen active use in the depths of SLTA in winter, kept out the weather on game shoots in Germany and UK, had roe grallocked on it in the Lake District, and been used by the dog as a bed. Rather like its owner it is now a bit rough around the edges and niffs a bit.
Those poachers pockets are handy for party goers, each has proved capable of holding 2 six packs of beer ( but the weight buggers your neck and shoulders), or scoff.
Returning from a trip abroad, Calais customs (Frog variant) asked me to empty my pockets: 8 bottles of wine, 3 loaves, assorted lumps of cheese and pate, 40 Gauloise.... "Is that a fucking magician's coat? Where's the rabbit?" asked (in French, of course) the officer. So I emptied the other pocket, he took umbrage and sent me on my way.
