Wool, made in Switzerland! Size tag is a little faded but it looks like 56 Eur! Pit to pit is around 23 inches so probably a 45-46 chest! Made in Switzerland and sold by Bergdorf Goodman. Let me know if I can give you more details. Condition: no holes or stains. One sleeve button slightly chipped. One front button slightly loose (can easily be sewn tighter). Jackets shows slight signs of wear but no flaws (other than mentioned) and plenty of life. Looks super sharp with a nice shirt or sweater underneath. I bought it for myself but it’s a little big.
