White Crew Neck Undershirt

Verified claims

Invisible layering

Lay-flat collar, stay-tucked fit, and opaque fabric prevent show-through and bunching under dress shirts.

Moisture wicking

DropTemp moisture-wicking keeps you drier than cotton under a dress shirt.

Cooling

DropTemp wicks strongly during exertion and keeps you dry daily.

Care

Cold gentle wash and low tumble dry protect the fabric and wicking properties.

Durability

57% cotton, 38% modal, 5% spandex blend resists shrinkage, pilling, and retains shape and strength.

Price positioning

$24.95: double multipack cotton, quarter luxury; modal wicking & stretch.

Fit

Slim, stay-tucked fit with lay-flat collar minimizes bulk and keeps shirt in place under dress shirts.

Opacity

White undershirt is opaque under most lightweight dress shirts, but show-through varies by outer fabric.

Sweat management

Lightweight wicking for moderate sweaters, without underarm pads.

Value

Roughly double the per-shirt cost of a Calvin Klein 5-pack for modal and DropTemp.

Brand origin

Saxx is a Vancouver-founded Canadian brand available at Simon's.

Long-term wear and washing durability

• Modal’s inherent elasticity and fiber strength give the blend the ability to hold its original form through many wash-and-wear cycles, meaning the undershirt’s slim fit stays close to the body rather than bagging out or losing its line.
• By combining cotton with modal, the fabric’s overall tensile strength increases, allowing the undershirt to be washed and worn on a regular basis without premature thinning or tearing — a step up from an all-cotton single-jersey in terms of mechanical endurance.
• The modal component in the blend sharply reduces the laundering shrinkage typical of 100% cotton — cotton alone tends to contract significantly after washing, whereas modal’s presence keeps dimensional changes minimal so the slim-fit undershirt doesn’t tighten up over time.
• Modal’s smooth fiber structure naturally resists pilling and surface fuzz, so the undershirt maintains a cleaner, less worn appearance at the fabric surface even after dozens of washes, unlike some pure cotton knits that develop pills from friction under dress shirts.
• Modal’s improved color retention compared to cotton means the white shade resists dulling or yellowing over time, a benefit for this all-white undershirt that must stay crisp under a dress shirt; SAXX care instructions further recommend non-chlorine bleach only and low-heat ironing to preserve the bright finish.
• Because modal retains 50–70% of its dry strength when wet (versus 50–55% for standard viscose), the fabric is less prone to weakening and deformation during machine washing, giving it an edge over pure cotton or lower-grade rayon undershirts in wet conditions.
• Research on single-jersey fabrics found that cotton/modal blends delivered the highest bursting strength values compared to pure cotton or other cellulosic blends, which translates to better resistance to the small punctures and stress points that develop at seams and underarm areas after repeated laundering.
• SAXX specifies cold water machine wash on a gentle cycle and low-temperature tumble drying, with an optional line dry to further preserve the stretch modal’s softness and prevent cumulative heat damage that shortens the garment’s lifespan.

How it stacks up against similar undershirts

• Priced at $24.95 CAD per single, this Saxx undershirt costs about double the per-shirt cost of a Calvin Klein 5-pack ($65 for five, roughly $13 each), but the difference buys a modal-blend fabric and DropTemp active cooling — an affordable step up from entry-level multipacks for those who want performance without reaching the $115 luxury tier of something like CDLP's Lightweight T-Shirt.
• SAXX is a Canadian brand founded in Vancouver, and this undershirt is available through Simon's — a heritage Canadian department store — giving it a local identity that distinguishes it from global players like Uniqlo (Japan) or Tommy John (US) for shoppers who prioritize domestic brands.
• Tommy John undershirts are engineered around a tailored, no-adjustment fit that stays tucked and disappears under clothes, while SAXX, rooted in athletic gear, prioritizes active cooling — making this crew neck the choice for buyers who want moisture-wicking performance first, rather than a dress-shirt-specific cut.
• Unlike specialized sweat-proof undershirts like EJIS or Thompson Tee that use built-in underarm pads to stop pit stains, Saxx relies on lightweight all-over DropTemp moisture-wicking without added bulk — a better fit for everyday wear where comfort and invisibility under a dress shirt matter more than heavy-duty sweat containment.
