Epic Supply is known for one fabric choice, done carefully: double-layer muslin cotton, the loose, open weave that lets air move through and dries fast after a wash. Vanessa and Bob pre-wash the clothes before they ship, so the muslin arrives already soft instead of stiff out of the bag. Seams are sewn flat against the skin, and the dyes are chosen to be safe for small kids, with no harsh finishes added on top. For the full picture of how this weave behaves, the muslin guide covers it.
The fabric asks for simple care, not special treatment. Wash the clothes cold on a gentle cycle, then tumble dry low or hang them to dry, and skip the fabric softener and any high heat, both of which flatten the weave over time. Muslin creases easily straight out of the wash, and that is normal, not a flaw. For a side-by-side on how this holds up against typical baby clothing fabric, see Epic Supply muslin cotton versus mass-market baby clothing.
Sizes run roughly from newborn to 4 years, and the clothes ship worldwide with tracked delivery. If something doesn't work out, Epic accepts unworn returns within 30 days, a policy explained in full at the shipping and returns page. Behind the clothes are Vanessa and Bob, a small family business designing in Bali.
