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.
Verified claims
- Chafe prevention
- Sidewalls prevent chafing when swim trunks are saturated.
- Design heritage
- Pouch design unchanged from 2006 underwear collection.
- Cooling
- DropTemp's active wicking keeps you dry for over 7 hours in 93°F heat.
- Wash durability
- DropTemp fabric stays stretchy and resists wear after washing.
- Value
- Priced at $85 CAD full retail (often $49.95 CAD on sale), Saxx packs more swim-specific features than Lululemon's $78 USD Pool Short.
- Liner
- Built-in boxer brief with BallPark Pouch and phone pocket replaces mesh liner.
- Brand heritage
- Saxx has used the same patented BallPark Pouch design since 2006, and a heavy-use Daily Beast reviewer said he will replace this suit with another from SAXX.
- Construction philosophy
- Shell designed around pre-existing boxer-brief liner with BallPark Pouch.
- Sizing
- Measure your natural waist just above the belly button, not at the hipbone or by pant size.
- Fit style
- Built liner-first: relaxed outer shell, form-fitting inner liner for a casual supportive fit.
- Chafe reduction
- BallPark Pouch and boxer-brief liner reduce groin and thigh chafing.
- Air venting
- Balloon's Away Vent releases trapped air underwater.
- Construction design
- Integrated design features including air vent, form-fitting liner, and anchored pocket reduce fabric strain, with the BallPark Pouch design validated since 2006.
- Repeat purchase
- A Daily Beast reviewer who used the trunks heavily said he will replace this suit with another from SAXX, indicating repeat-purchase intent.
- Versatility
- DropTemp and integrated liner allow pool-to-street wear without underwear.
- Phone pocket security
- The built-in liner has a hidden phone pocket on the left thigh that holds a phone tight to the leg, so it doesn't bounce or pull the shell out of shape.
- UV protection
- The fabric does not carry a listed UPF rating, so its UV protection is unconfirmed.
- DropTemp activation
- DropTemp activates with any moisture source, including sweat; it does not require full submersion in water.
- Liner drying speed
- Despite the full boxer-brief coverage, the liner dries as quickly as a traditional mesh brief.

A lightweight swim trunk for beach and pool days
These mid-thigh trunks are made for swimming and lounging poolside, cut with a straight hem that finishes above the mid-thigh as shown on the model. The light, non-cling stretch fabric is fast-drying, so the trunks move with you in the water and dry out quickly afterward. A drawcord-adjustable elastic waist lets you tighten the fit at the natural waist.[1,2,3]
Staying cool and dry at the beach or pool
For swim days when heat and humidity leave you feeling sticky, this trunk's DropTemp™ technology is designed to wick away moisture and support your body's natural cooling. A vent at the fly also lets trapped air escape, helping you stay comfortable in and out of the water.[1]
Swim trunks designed to reduce chafing
For men looking for swimwear that keeps things comfortable in and out of the water, these trunks feature a built-in boxer with a micro mesh 3D BallPark Pouch front that the brand says prevents skin-against-skin friction. The built-in boxer also adds a thigh pocket for a cell phone.[1]
Keeping your phone and essentials secure at the beach or pool
These swim trunks are built for swimming with your belongings on hand. The built-in boxer includes a cell-phone pocket on the thigh, while the outer trunk adds a hidden side-seam zip pocket, vertical slit pockets, and a piped back pocket for carrying keys, cards, or other small personal items.[1]
