Waxing / Waning T-Shirt | Umbravoid
The Moon keeps its own calendar: waxing from new to full as light grows, waning back to dark as it fades. Learn the rhythm and you can read the sky at a glance — and know exactly when the nights go dark enough for deep-sky hunting. 'Waxing / Waning' wears that lunar cycle clean and simple. For Moon watchers, stargazers, and anyone who plans their nights by the phase. A premium astronomy tee for the lunar-literate. Available in 7 sizes (S–4XL) and 10 colorways.
