With 4mm Clasico Integrated Pad and seamless inner thigh


The Forza Trishort is by far one of the single most popular trishorts in the world. It is the foundation which started the entire compression industry dating back to 1997, when De Soto Sport was asked to test the very first compression fabrics for the Dupont Textile Company. 2 decades and many improvements later, you simply cannot go wrong in owning this short.


  • 1" (2.54cm) lower in the rise than previous models making it more of a regular rise than a high rise.  This piece sits just below the hip bones.
  • 4mm Clasico Integrated Pad is softer with more stretch. The pad is sewn onto the surrounding panels instead of inside the garment, so there are no seams on any part of where you sit. We have eliminated the Ceramico beads.  Now on the outside you will find Liftfoil™ fabric that covers the pad.  It is smooth and allows for easier fore and aft movement on the saddle.
  • Seamless inner thigh eliminates friction and increases durability.


  • Made of Forza Compressor fabric (see Fabric Facts)
  • 3-inch 2-piece Mobius™ Comfort Compression leg-bands that offer compression without tight constriction (read details below).
  • No gripper elastic nor binding legbands that cause a tight squeeze of the thighs.
  • Solid black Liftfoil™ center panels providing even more comfort and durability. We intentionally kept these as black “modesty” panels in the crotch area of all models including the white version to avoid saddle stains while creating a more flattering appearance. Liftfoil™ is the swimskin fabric. The Liftfoil™ Speed Trisuit is made entirely out of this swimskin fabric. The addition of these panels on the front and back not only makes this trishort faster, but they eliminate any adverse affects when worn with a wetsuit.
  • Curvilinear™ seamlines, and contrast flatstitch offer support, comfort and both aerodynamic and hydrodynamic advantage making it great for nonwetsuit races.
  • Swim, bike, and run in comfort without changing. Wears well under your wetsuit!
  • Disclaimer: swimming in murky water, including ponds, streams, bays, etc. may cause staining
  • This environmentally-friendly innovation is completely free of solvents and the dyes used have no VOC.
  • Not recommended for repeated use in a chlorinated pool


A Mobius Strip is a surface with only one side and one boundary. Mobius™ Comfort is the new form-fitting, yet non-binding compressive fabric. The knit we created when blending fibers make repeated mobius loops so that the same surface, stretch, and rebound is on both sides of the fabric and in equal direction. You will notice comfort and support without constriction, opacity without unnecessary weight, and durability from a very smooth surface on both sides. In addition to the bibshort and trishort made entirely of this fabric, you will find Mobius Comfort leg bangs on all our trishorts, bike shorts, and bib shorts.


Yes, the Clasico Pad different from the Ceramico pad we offered previously.  First lets be clear on what remains the same.  The pad is still the same size, same thickness, same density, and same buoyancy.  It is still an integrated pad, meaning that it all the panels are sewn around the pad, so it has no stitching down the middle.  
The difference is that instead of the ceramic beads which were laminated to fabric that is laminated to the other side of the pad, we opted for covering it with fabric on the outside of the short.  In essence we removed two layers of lamination which caused a perception of stiffness, especially when the short was new.  
The new Clasico Pad looks less obvious, and it also allows the pad to stretch more than the Ceramico pad.  In an effort to keep improving the pads, the Clasico Integrated Pad offers the same padding, but with more stretch in every direction, and more comfort from the first time you wear it.
