Vintage EPI T-shirts - $5.00

Our little office is crammed full of t-shirts leftover from past field seasons, and it's time we did a little "spring" cleaning! All t-shirts are made either from a poly/cotton blend or from organic cotton (2015-2017), and they have a variety of logos and taglines on them from the different field seasons. We have limited sizes in all but the 2017 shirts - click below to view available sizes and colors. Collect them all before we have to turn them into a quilt for the office dogs!
