This isn't a triangular tag, but it's an 80's Patagonia Snap-T. Extremely rare, the earliest Snap-T. The back is split down the center, and the sleeves are one-piece. The vibrant French red and eggplant (purple-系) piping is superb, and this model is considered one of Patagonia's masterpieces and iconic colors.
