Sustainability

TENCEL Modal is EU Ecolabel certified with 50% lower carbon/water footprint and FSC/PEFC wood sourcing.

Design

Canadian-designed Simons exclusive with flat seams for a discreet fit.

Eco certifications

TENCEL™ Modal is EU Ecolabel-certified with 50% lower water/carbon; organic cotton is pesticide-free.

Durability

Anti-pilling and antibacterial properties keep the fabric smooth and fresh between washes, extending garment life.

Softness

47% organic cotton + 47% TENCEL Modal: fibers 50% finer than cotton for silky softness that improves with washing.

Skin comfort

Flat seams, chemical-free organic cotton, and moisture-wicking TENCEL Modal enhance skin comfort and discretion.

Care

Avoid fabric softener and high heat; cold wash and air dry for softness; Modal's antibacterial nature reduces wash frequency.

Seam and waistband

Flat seams prevent visible panty lines, and the waistband stays in place without digging in or leaving a mark.

Fabric performance

Ultra-fine modal fibers keep the fabric smooth, shrink minimally, and resist pilling for long-lasting discreet fit.

Moisture wicking and breathability

Organic cotton and TENCEL Modal blend wicks moisture and breathes better than all-cotton for light activity and warmth.

Odor resistance

Natural antibacterial and breathable materials cut odor for rewear.

Color retention

TENCEL Modal locks dye and resists pilling, keeping colors vibrant through washes.

Wash frequency

TENCEL Modal's odor resistance reduces wash frequency, limiting fading.

Eco-credentials of the organic cotton and TENCEL Modal

• TENCEL™ Modal fibers hold the EU Ecolabel for textile products (license AT/016/001), an independent verification that the fiber meets reduced-impact criteria across multiple life-cycle stages, giving this garment a recognized eco-certification at the material level.
• The TENCEL™ Modal manufacturing process uses resource-efficient technology with high chemical recovery rates, curbing the release of processing agents into the environment and further lowering the fiber’s production-phase impact.
• The wood pulp for TENCEL™ Modal is sourced from forests certified to FSC® or PEFC standards, ensuring the wood comes from responsibly managed, non-endangered sources and tying the material to forest conservation rather than deforestation.
• TENCEL™ Modal production has a Higg MSI-verified footprint at least 50% lower in carbon emissions and water consumption compared to generic modal, so the modal portion of the fabric is manufactured with significantly less environmental strain.
• Because organic cotton cultivation prohibits synthetic pesticides, this garment avoids the heavy chemical inputs of conventional cotton farming—U.S. conventional cotton fields averaged 3.8 pounds of pesticides per acre in 2017—which means the cotton in this blend comes from a lower-chemical-input supply chain.

Wash durability and long-term care

• Using fabric softener on this TENCEL Modal boyshort is counterproductive: the softener’s chemical film coats the microporous fiber structure, sealing off the airflow and moisture escape pathways that give the blend its temperature-regulating, stay-dry advantage over basic cotton.
• The modal component in this blend has a strong affinity for dyes, locking in pigment much better than organic cotton alone — meaning the black, sand, or slate-blue colorways retain their saturation after repeated laundering rather than fading to a dull, washed-out look.
• The tumble dryer’s combination of heat and mechanical action degrades the modal fibers’ surface, promoting roughness and pilling while triggering cotton shrinkage — flat air drying preserves the smooth, stretchy jersey texture and the boyshort’s original fit.
• Modal fibers lose 3–5% of their dimension in a single hot-water wash, and because cotton shrinks at an even greater rate, the organic-cotton component in this blend will pull the modal fibers tighter if the boyshort ever sees a warm cycle or tumble dryer — sticking to cold water and flat drying is the only way to maintain the tagged size.
• The native smoothness and uniformity of TENCEL Modal fibers give this boyshort a surface that resists the fuzz-ball formation that plagues many cotton-knit undies after multiple washes, so the fabric stays sleek to the touch far longer than pure cotton jersey.
• TENCEL Modal carries inherent antibacterial properties that prevent odor buildup, so unlike pure cotton underwear that typically demands daily washing, this boyshort can be aired out and worn an extra day or two — reducing wash cycles and delaying the gradual wear on the elastic waistband and fabric.

How the organic cotton and TENCEL Modal blend feels all day

• Flat seams eliminate raised edges that could dig into skin or create visible panty lines, making these boyshorts invisible under snug clothing and increasing all-day comfort by removing potential pressure points.
• Compared to cotton's 3–10% shrinkage range, modal typically experiences only 3–5% shrinkage, so the boyshort is less likely to tighten or distort after repeated washing, preserving its intended fit and eliminating the stiffening that cotton often undergoes over time.
• Because the organic cotton component is grown without synthetic pesticides or fertilizers, the fabric places fewer residual chemicals against the skin — particularly beneficial for wearers with contact sensitivities or those who prefer a cleaner, skin-safe everyday garment.
• TENCEL Modal fibers measure roughly 0.5 dtex compared to cotton's 1.0–1.5 dtex, making them about 50% finer; the resulting ultra-smooth surface creates less friction against skin and gives the fabric a noticeably silkier hand feel than standard pure cotton, which is why this boyshort feels luxurious rather than utilitarian.
• A home wash test of Lenzing Modal found zero pilling and increased softness after 20 machine washes, while the same test's cotton sample pilled noticeably; this implies the TENCEL Modal in this blend helps the fabric hold its smooth, pill-free surface over time, becoming more comfortable with use rather than degrading.
• The modal component supplies an ultra-silky, soft touch that wicks moisture, while the organic cotton adds natural breathability and a gentle, non-abrasive surface — together they create a fabric that feels indulgent against the skin without sacrificing the airiness and familiarity that makes cotton comfortable for all-day wear.
