I see that the hatbox has a new type of suit that's very light and thin (by Zeke). Somebody told me it's about $250 for the suit so if they sell the jacket alone, I imagine it would be about $150ish

Hat box has a stretch unlined jacket which I love. Only cons are weird stitching on the sleeve, and a little slippery for Tallis. But it’s super lightweight, great stretch, not terribly expensive ($150) and looks pretty good.
