Smoother feel than mesh boxer briefs despite micro-perforations.

Maintenance

Fabric softener reduces wicking efficiency by up to 50%.

Ventilation

The fly front uses a mesh pouch that adds cooling and support.

Price-value comparison with Saxx, Under Armour, and others

• Wirecutter’s 2026 review of the best men’s boxer briefs evaluated pairs costing up to $35 USD; at $19.99 CAD, the Stanfield’s Dryfx lands in the lower half of that band, bringing Canadian manufacturing and SPF 50+ to a price tier where few offer both domestic production and sun protection.
• Leonisa’s boxer brief with mesh cutouts sells for $38 CAD and is made in Colombia, nearly two times the $19.99 CAD sale price of the Stanfield’s Dryfx, which matches its polyamide-based breathability and adds SPF 50+ and Canadian origin, making the Dryfx a more cost-effective alternative for active wear in sunny conditions.
• Under Armour’s entry-level performance boxer brief retails for $20 USD without any SPF rating, while Stanfield’s Dryfx at $19.99 CAD (approximately $14 USD) delivers comparable moisture-wicking and a 6-inch inseam plus SPF 50+ and Canadian manufacturing — effectively twice the value for a sun-conscious buyer.

How DryFX cooling technology keeps you cool

• The nylon blend is rated SPF 50+ (blocking >98% of UV radiation), an unusual specification for underwear that turns the brief into a legitimate sun-protective garment — for outdoor work, cycling, or sports, the fabric itself reduces UV exposure and the associated skin heat, extending comfort during prolonged sun.
• The front pouch is constructed from a 94% nylon / 6% spandex open mesh instead of the solid jersey, which targets additional cooling airflow to the most heat-trapping zone — for a boxer brief worn during summer runs or on the job site, this design keeps the fly area noticeably drier and less prone to chafe than an all-jersey construction.
• The body fabric is an 87% nylon / 13% spandex blend with micro-perforations that accelerate moisture transfer to the fabric surface and air circulation through the textile, so the cooling effect is primarily evaporative — the fabric's 'cool-to-the-touch' sensation is enhanced by the rapid drying that prevents sweat from clinging, which makes this brief more effective during high-exertion activities than a standard synthetic tight.

Nylon-spandex blend vs cotton and other materials

• Stanfield's proprietary Cool Fibre Technology chemically embeds a cool-to-the-touch sensation into the nylon filaments, so the fabric actively dissipates skin heat the moment you pull it on — an engineered feature meant to maintain thermal comfort during high-exertion work or exercise, not just passive breathability.
• With 94% nylon and 6% spandex, the Dryfx fabric lands in the performance window where nylon-spandex blends deliver moderate stretch and strong recovery without the compressive feel of higher-spandex shapewear — the result is a brief that moves with you but doesn’t squeeze, prioritizing unrestricted motion and quick-dry capability over sculpted compression.
• The Dryfx nylon-spandex mesh actively wicks sweat off the skin and spreads it to the outer surface where it evaporates, unlike cotton briefs that absorb and hold moisture against the body — that means you stay drier and less prone to the dampness-induced chafing typical of cotton during a workout or long shift.
• The fabric’s micro-perforations create thousands of pinpoint vents that boost convective airflow through the nylon mesh, accelerating sweat evaporation without the abrasive feel of open-hole mesh — this is what allows the Dryfx to breathe more like a performance running tee than a standard cotton boxer brief.

What Canadian manufacturing means for quality and ethics

• Stanfield's has been a Canadian manufacturer since 1856 and still sews its core underwear line in Truro, Nova Scotia — meaning these Dryfx boxer briefs inherit nearly 170 years of textile production expertise and process refinement inside the same community.
