BCG is short for Ballistocardiogram, the name printed on its labels. The look comes first: bows and ribbons, rivets, gradients, moto and racing graphics, faux denim and a retro “old-money” streak. Two 26/27 pieces show the range. The Retro Moto 2-in-1 jacket wears a detachable cropped cape over a full shell, so it works more than one way; the Graffiti Blade pants pair racing graphics with a curved, wide leg. Women’s styles are cut slim, unisex styles loose.

Every BCG style is a 3-layer shell with fully taped seams: a polyester face and a nylon lining. BCG rates its 26/27 shells at 20,000 mm waterproof (JIS L1092) and 19,000 to 25,000 g/m²/24h breathable (JIS L1099). Most jackets have two pit zips, and every style has a powder skirt or gaiter. The 26/27 shells are not insulated, so the warmth comes from what you wear underneath: a base layer always, a mid-layer on cold days.

BCG’s own fit guide puts its M at 170–175 cm and 55–60 kg and its XL at 175–180 cm and 65–70 kg, so many riders here size up; garment measurements are on every product page. Its studio photos use a 171 cm model in an M. Care is strict: hand wash only, with no machine wash, tumble dry or iron.
