What size shirt do you normally wear?
I wear a 2XL. I'm 6'3" but short legs (31 inch inseam). Yep all torso with short legs. So I have to use Amazon's Big and Tall, then search from there.
I see stuff "sale price" at amazon for $13.50. Yippee... click 2x tall and it's $35. Grrrrrr.
One random item. Champion brand 2XL Tall running jacket.
I like wearing high visibility orange/green depending on weather. So my wife has been able to snag jackets after hunting season! Even on our trails, my Golden Retriever is running along side (hard to spot!) but the high vis clothing gives bicyclist a chance to see and avoid us a little easier
