The Fifth Set Launches SweatRoute Patented Technology Enhanced Tennis Shorts


The Fifth Set Combines Science with Style to Empower Professionals and Amateurs to Sweat Hard and Play Dry with Patented “SweatRoute” Technology

The game of tennis just got upgraded thanks to “SweatRoute” technology developed by The Fifth Set, a tennis apparel company. First up, are men’s shorts launched today offering breathable and sweatproof materials that help you stay dry and comfortable, and perhaps more importantly, has pocket enhanced tech that keeps the ball dry from sweaty short pockets of old. The startup is based in Parkland, Florida and offers five key innovations in their short design – waterproof but breathable pocket liners, heat-sealed pocket liner interface, water-resistant body, pocket opening closed-at-rest, and routing vein around the pocket opening. The Sports Techie community blog tennis playing readers and followers can find this first product that kicks off its inaugural collection, available exclusively at The retail price for the unique men’s shorts is $72.00 and comes in three colors and four different sizes.

The Fifth Set’s patented shorts offered three key differentiators: 1. Sweatproof 2. Breathable 3. Accessible

Business Concept and Plan

Launched in March 2023, The Fifth Set provides customers with patented “SweatRoute” technology to keep tennis enthusiasts dry, comfortable, and at the top of their game.

Previous to today’s launch, a Kickstarter crowdsourcing campaign was successful for the South Florida startup with more than $9,000 generated through pre-orders of the tennis shorts.

How was this so?

The Fifth Set’s patented shorts offered three key differentiators:

  1. Sweatproof: Pocket liners are constructed with a waterproof layer and heat-sealed seam. Combined with a water-resistant outer body, the shorts redirect moisture to keep tennis balls fully protected.
  2. Breathable: The body and pocket liners are breathable to promote comfort, as well as quick and agile movement. The pocket liner’s microporous, waterproof layer protects from sweat while keeping the player cool. 
  3. Accessible: Pocket openings are unsealed, but stay closed, preventing sweat from seeping in and allowing quick accessibility for frequent use.

“The Fifth Set is a labor of love that solves a real problem that plagued my game for nearly 30 years — wet tennis balls from sweat-drenched pockets, causing a ‘sweat tsunami’ whenever I served,” said Yoni Malchi, The Fifth Set’s CEO and founder, as well as a lifelong tennis player. “After discovering a void in the market for tennis shorts with waterproof, breathable, and accessible pockets, I received a patent on my own design, which is a game-changer for tennis players at every level.”

The innovative company plans to follow up the launch of men’s tennis shorts to an expanded product line, featuring its SweatRoute-patented technology. Look for The Fifth Set to also introduce its brand ambassador program over the next several months as well as broadening the scope of its affiliate network.


Yoni Malchi, has worked in the data and analytics industries and earlier in his career, he served as Combustion Specialist for the United States Air Force and NASA supporting the first-stage rocket engine on all satellite launches. Danielle Malchi, Yoni’s wife, is the other co-founder and works for Century 21 Stein Posner in Boca Raton.

“During the pandemic, one of the biggest retail trends that evolved was that consumers have become more demanding for unique, top-quality products that are also function-specific,” said Danielle Malchi, co-founder of The Fifth Set. “With more people focused on fitness than ever before, consumers are seeking truly innovative products to help them reach their personal goals and needs, and we are here to support them in this endeavor.”

Sports Techie, picture this – a former aerospace engineer with a passion for tennis living in hot Florida, invents SweatRoute technology, then together with his equally as passionate wife, formed a startup, raised seed money from a crowdsource platform, and launched breathable and sweatproof men’s shorts that keeps sports enthusiasts dry and comfortable while at the top of their game.

This kind of pioneering innovation is what Wilson Labs delivers in their Shift v1 performance tennis rackets.

Like promoter Don King says, “Only in America!”

I am an athletic sweater, therefore, this long overdue concept of keeping a tennis ball stashed in your pocket dry from sweat for a second serve, or a smartphone, remote keys or a Ready protein bar for that matter, is about time.

Let the Malchi’s or me know about your feedback regarding these innovative men’s tennis shorts.

Keep it dry with The Fifth Set.
