Product Insights

Solid Stretch Boyshort Tencel™ Modal from Miiyu is a sustainably certified boyshort that derives its softness from fiber structure, not chemical softeners, and offers 50% greater absorbency than cotton, eliminating the need for a separate gusset. The fabric resists pilling (grade 4-5) and shrinkage (3-5%), snaps back after wear, and features a wide flat waistband and full-coverage boyshort cut that prevents ride-up. Fits true to size (XS–XL, comparable to Aerie) and is endorsed by Reddit buyers as a quality alternative at Simons. Priced at $12.99 ($7.99 in 5-pack) it undercuts similar sustainable modal boyshorts by $2–$7, with EU Ecolabel, Canopy Dark Green Shirt, and Higg MSI certification reflecting 50% lower emissions and water use.

Pas de serrement au niveau des cuisses et de la taille. Super confortable.

Just okay

Mon T.

I got 5 of them cause I love hotshots but was trying to find something outside VS. They fit okay, however, I can tell that they won’t last very well. Some of them already came with tiny snags, and I can’t be bothered to return undergarments. So now, they’re my back up ones.
