Fabric guide

What is Lenzing Modal, and why does Nat'v Basics use it?

Lenzing™ Modal is a soft, breathable fabric made from sustainably sourced beech wood pulp. It is used across Nat'v Basics g-strings, briefs and crops because it is lightweight, stretchy, moisture-wicking and gentle on skin, giving a semi-seamless, barely-there feel with minimal visible panty line.

What is TENCEL, and how is it different from Modal?

TENCEL™ is Lenzing's branded lyocell fibre, also made from wood pulp in a closed-loop process that recycles water and solvent. Nat'v Basics uses TENCEL™ in styles like the It's A G micro g-string and Callie Brief for a smooth, cool-to-touch, breathable finish. Modal and TENCEL are similar in softness; TENCEL is typically a touch more durable and moisture-managing.

Does Nat'v Basics use organic cotton?

Yes. Several Nat'v Basics styles, including the Halo Organic Cotton G-String, the Classic Crop, the Vintage Nighty and the Ribbed range are made from GOTS-certified organic cotton, chosen for breathability and gentleness on sensitive skin.
