I got this amazing Idaho sweatshirt recently. This is an Awesome Yellow Vintage Idaho Short Sleeve Champion Sweatshirt size Lg. Upon my research I can see that this is from the 1960s from the Champion tag.

This is in excellent condition still very soft not at all stretched out . Elastic is still good on the neck, arms and hem.

Marked size large, but do check the measurements. Measures Underarm to underarm 21" Across the shoulders is 19" Underarm to hem 14" Collar to hem 24"
