Why the gusset material matters
Most period underwear uses a synthetic gusset. As an example a shopper can verify independently: LOLA publishes its own period underwear composition as a 100% polyester gusset with an 87% polyester / 13% polyamide core and a polyester-with-TPU leakproof barrier. Ashers use organic cotton and modal instead. Both facts come from the brands' own published material lists.
