Frequently Asked Questions
Should I size up or down?
It runs true to the size chart with a normal cut — not boxy, not painted-on. Check your chest measurement against the chart in the photos; between sizes, up is the safer turn for everyday wear.
Will it shrink in the wash?
Cold water and a low tumble keeps the fit — that is how these are meant to be washed. Hot water and a hot dryer are what shrink any cotton tee, so keep the heat off and yours stays true.
What does the fabric feel like?
Soft and light with a smooth hand — the kind you forget you are wearing. The knit gives just enough that it moves with you instead of clinging.
Is it breathable for summer?
Yes — the knit lets air through and wicks rather than traps, so hot days and workouts are both fine. It dries fast if it gets damp.
Is the color true to the photos?
Yes, and it holds after washing — the dye is set properly, so no pink-tinged grays here. Do give new dark pieces their own first wash just in case.
