Product Insights
Saxx's Built-In Boxer Swim Trunk integrates a boxer-brief liner with the BallPark Pouch (unchanged since 2006) for chafe prevention and support, featuring sidewalls that prevent chafing when saturated, an air vent to release trapped air underwater, and DropTemp active wicking that keeps you dry for over 7 hours in 93°F heat. The shell is designed around the liner for a relaxed fit, with a quick-drying mesh pocket. It offers versatility for pool-to-street wear without underwear, but comes at a higher price ($85 CAD), though it delivers more swim features than the Lululemon Pool Short.
- Chafe prevention
Sidewalls prevent chafing when swim trunks are saturated.
Why this is supported
WearTesters confirmed that the BallPark Pouch's sidewalls protect against friction when trunks are fully saturated:
The sidewalls of the BallPark Pouch protect the frank and beans from rubbing against the inside of the legs.
weartesters.comOne tester reported that the design meant using less anti-chafe balm:
Most runners use BodyGlide or some other irritation/chafing protector before longer runs. The Saxx design means using less anti-chafe balm which is a win in my book.
weartesters.comSAXX explains that the integrated liner is form-fitting through the butt and thighs to further reduce chafing:
The integrated liner is form-fitting through the butt and thighs.

Pouch design unchanged from 2006 underwear collection.
Why this is supported
SAXX states:
Comfort and support are built right into the shorts, thanks to the patented BallPark Pouch™– the same great pouch from our underwear collection– and an integrated liner.
saxxunderwear.caWearTesters confirms the heritage:
Saxx was founded in 2006 and has made underwear ever since.

The Balloons Away Vent™ prevents those unwanted underwater air bubbles before they happen.
saxxunderwear.ca- Cooling
DropTemp's active wicking keeps you dry for over 7 hours in 93°F heat.
Why this is supported
DropTemp uses an active wicking mechanism that accelerates evaporative cooling, unlike standard mesh liners. A reviewer on a 93°F day reported:
Not once did I feel sticky, uncomfortable, or bunched up underneath my pants.
reviewed.comAnother source notes the wicking is so aggressive it leaves condensation on vinyl seats:
So much so, that DropTemp boxers combined with quick drying shorts will leave condensation on vinyl seats in humid conditions.
campfederalland.comThis confirms that the cooling effect is sustained in high-heat, humid conditions.
- Wash durability
DropTemp fabric stays stretchy and resists wear after washing.
Why this is supported
After machine washing and drying, the DropTemp fabric showed no loss of stretch or visible wear:
After throwing the Saxx apparel in the wash, everything returned clean and stretchy with no obvious signs of wear.
insidehook.comThis indicates that the wicking performance and fabric integrity persist through regular laundering.
- Value
Priced at $85 CAD (often $49.95), Saxx delivers more swim features than Lululemon's $78 Pool Short.
Why this is supported
Catalog confirms the Saxx swim trunk is priced at $85 CAD full retail and often on sale for $49.95 CAD, offering
