Signature-Stripe Blue Swim Trunk

Verified claims

Stretch recovery

100% elastomultiester bicomponent recovers 85-98%, resists bagging.

Durability

Chlorine- and wash-resistant fabric dries fast, maintaining shape.

Quick-dry performance

100% elastomultiester shell and mesh liner dry trunks faster than cotton, nylon, and many competitors.

Competitive value

At CAD 99, matches L.L.Bean's price; 65% premium over Quince for stripe design and BOSS name.

Liner

Mesh brief liner offers lighter fit and faster drainage than L.L.Bean's boxer brief liner.

Fit

5.75-inch inseam is shorter and more fashion-forward than L.L.Bean's 8-inch, with drawcord to preserve the silhouette.

Silhouette

Drawcord, stretch fabric, and mesh liner keep the 5.75-inch hemline sharp and stable, wet or dry, season after season.

Chlorine resistance

Elastomultiester resists chlorine degradation better than spandex, maintaining shape and stretch recovery

Saltwater resistance

Brand literature states the fabric resists saltwater and maintains color in ocean water

Quick-drying

Hydrophobic polyester base and mesh liner provide rapid drying and water drainage

Care

Cold wash and hang-dry; high heat not recommended.

Signature stripe

Signature stripe is a recurring BOSS brand motif with retro sporty appeal.

Waist sizing

Waist sizing matches US pant sizes and stretch fabric fits most builds.

Waist comfort

Mesh liner is lightweight and fabric dries quickly for chafe-free wear.

Inseam control

Cinching drawcord above hips maintains 5.75-inch inseam above knee.

Pocket drainage

Pockets lack drainage holes and are not secure in water.

Inseam length and coverage

• The drawcord-adjustable elastic waist is the functional anchor that preserves the 5.75-inch inseam’s intended geometry across different builds — by cinching above the hips, it prevents the leg line from migrating downward even when the waist is sized up for a fuller thigh, so the hem stays in a consistent above-knee zone instead of sagging into a mid-thigh or knee-skimming position.
• The elastomultiester stretch fabric — a high-recovery polyester-blend — eliminates the boxy, static drape of non-stretch nylon, so the 5.75-inch leg opening follows the thigh’s curve without flaring outward; this keeps the trunk’s silhouette sharp even after hours of wear and multiple transitions between water and land.
• Within the BOSS lineup, the Signature-Stripe trunk’s 5.75-inch inseam represents the more coverage-oriented option compared to the 5-inch Iconic short; that extra 0.75 inches adds tangible leg cover without crossing into board-short territory, making it the pick for someone who wants the brand’s signature sporty look but doesn’t want to fully commit to a 5-inch cut.

Long-term durability and care

• The fabric’s hydrophobic polyester base sheds water rapidly, drying far faster than cotton or nylon suits — this reduces moisture‑borne bacteria growth and makes the recommended hang‑dry process a quick, practical step that avoids the elastic‑damaging heat of a machine dryer.
• Elastomultiester’s bicomponent polyester structure delivers superior shape recovery and stronger chlorine resistance than spandex, so these trunks resist the bagging and sagging that often plagues elastane-blend swim shorts after repeated pool use.

Mesh liner support and comfort

• The mesh construction promotes superior water drainage, ensuring the trunks stay lightweight when wet and dry faster than trunks with solid liners — a practical benefit when transitioning from water to beach bar without a long soggy interval.

Elastomultiester fabric properties and performance

• BOSS specifies the fabric as quick-dry, a performance characteristic rooted in elastomultiester’s hydrophobic polyester nature that sheds water quickly and stays lightweight even after getting out of the ocean—no heavy, dripping trunk dragging your afternoon beach walk.
• The elastic mechanism in elastomultiester is built into the polymer chains rather than added as a separate chemical component, so the recovery performance survives repeated laundry cycles intact—no gradual loosening like you get with spandex-blend trunks after one summer of washing.
• With a 15–30% elongation and 85–98% recovery rate in woven form, elastomultiester behaves like a 2–5% Lycra blend’s stretch but snaps back far more reliably—meaning these trunks won’t bag out at the knees or seat even when you’re sitting wet on a pool ledge.
• This BOSS swim trunk uses a 100% elastomultiester shell, a polyester fiber that generates stretch through a side-by-side bicomponent structure of PET and PTT polymers—not spandex—which creates a permanent helical crimp for inherent elasticity, so the shorts won’t lose their shape after repeated wet-dry cycles the way elastane-blend suits do.
• Unlike elastane—which chlorine attacks chemically, causing fibers to weaken and lose stretch—elastomultiester’s stretch is a physical property of its polyester molecular structure, so the trunks won’t sag or lose compression after repeated pool sessions, a longevity edge that matters if these are your daily swim laps suit.
