The plainest shirt in the inventory, and the one that says the most. The RADCON crest — Radiological Controls, Groton, Connecticut, the orbiting atom around its trefoil core — is embroidered onto the left chest, thread not transfer, so it holds through every wash with no cracking or fade. The blank is honest workwear: heavyweight 5.0–5.3 oz cotton, open-end yarn and tubular knit for durability, taped neck and shoulders and double-stitched hems so it keeps its shape instead of its receipt. Wear it solo or as a base layer. Trends are temporary; construction isn't.
