95% organic cotton (Gossypium hirsutum) and 5% elastane for stretch and recovery. No polyester, no nylon, no synthetic friction fibres. We list it like a skincare label — because that is how we think about what touches your skin.

It is designed for it. Natural cotton against the skin, flat-locked seams, zero synthetic friction, and OEKO-TEX® Standard 100 certification — tested against 100+ harmful substances, with no coatings or pH-disruptive finishes.

Because the hour your skin is most exposed should not be the hour it is sealed in plastic. Natural cotton carries heat and moisture away from the skin; synthetics trap heat, friction and occlusion against the barrier — exactly when it is most vulnerable.

No. The cotton is knit dense and the 5% elastane keeps it fully opaque at the deepest squat — in both White and Charcoal. Opacity that holds, wash after wash.

It holds. The 5% elastane gives the cotton recovery, so the waistband stays put and the shape returns wash after wash — no bagging at the knee or seat.

The Short runs XS–XL; the Bra, Top and Routine Set come in S/M and L/XL. Between sizes, size down for a second-skin fit, up for a relaxed one.

Cold wash inside out, line dry, no fabric softener. The colour holds, the structure holds — built for a hundred wears, not a single season.

Drop 01 is limited to 100 sets, made by hand in Budapest. The waitlist is invited first — before anyone else — with a $50 founding credit. Join the list and you will be the first to know the moment it opens.

Your skin barrier is its first line of defence — and during a workout it is at its most compromised: temperature up, pores open, pH shifted. Most clothing is designed for movement. SECOND. is designed around the barrier. Skin is first. We are second.
