Mens Triathlon Shorts with Adjustable Drawstring - MK TRI 2.0 Chamois

Our review of these MY KILOMETRE Mens Triathlon Shorts finds them aimed squarely at serious triathletes who want a single short that performs for swim, bike and run. The biggest reason to buy is the MK TRI 2.0 multi density chamois shaped for the aero position, which makes the shorts comfortable on long rides without getting in the way for the run. Built from 80% polyamide and 20% Xtra Life Lycra, they combine chlorine resistance and UPF 50+ coverage with muscle compression and a streamlined fit.

Key Features

• Durable fabric: The 80% polyamide and 20% Xtra Life Lycra blend offers chlorine resistance and UPF 50+ protection for training in pools and sunny conditions.
• Performance compression: The fabric provides targeted muscle compression to improve aerodynamics and reduce fatigue during long-distance efforts.
• MK TRI 2.0 chamois: A multi density pad designed for the aero position gives sustained comfort on the bike while remaining unobtrusive for the run.
• Adjustable drawstring: The waist tie lets athletes fine tune fit for different phases of a race or layered clothing setups.
• Easy-reach leg pockets: Nutrition pockets on each side of the legs allow quick access to gels and bars while riding or running.
• Secure leg ending: Wide elastic leg hems with silicone print hold the shorts in place through both pedal strokes and strides.

Who It's For

These shorts suit competitive and training triathletes who need a single race-ready garment for swim-bike-run transitions and long distances. The blend of chlorine resistance, UPF protection and a chamois shaped for aero riding makes them appropriate for open water or pool swimmers who then spend extended time on the bike.

Less suitable are athletes who prefer separate heavy-duty cycling bibs for long road rides or swimmers who want a dedicated swim brief without any pad. If you need heavy padded protection for multi-hour saddle time beyond tri-specific positioning, a full cycling short with thicker chamois might be a better match.

Pros & Cons

Pros

• Chlorine resistant and UPF 50+ fabric that holds up to pool sessions and sun exposure.
• MK TRI 2.0 multi density chamois designed for aero position provides comfort during bike legs and reduces nuisance on the run.
• Convenient leg pockets and adjustable drawstring make nutrition and fit management straightforward during races.
• Elastic leg ending with silicone print keeps the shorts from riding up through transitions.

Cons

• The chamois is optimized for triathlon aero position and may feel thinner than dedicated long-distance cycling pads on extended road rides.

Our Verdict

These shorts are a sensible buy for triathletes who want a single technical garment for race day that handles swim exposure, provides aero-oriented padding and keeps nutrition at hand.
