I've got one just like that from Squak...Except they call theirs the Maverick and it weighs 132g in Medium...Probably because it's a loose fit for a medium so it has excess fabric, which adds weight. Mine could easily fit someone with a 44" chest, maybe bigger. It's about 75mm (3") longer than the OMM Core Hoody, so I finally have a garment that covers my builders bum when I am bending or squatting!
