Mens Triathlon Shorts with Adjustable Drawstring (Style 81ZJ)

In this review the MY KILOMETRE Mens Triathlon Shorts stand out as a practical, value-driven choice for multisport athletes who need a single short that handles swim, bike and run. The bottom line: these shorts are for triathletes who want chafe-free comfort and useful on-course storage without the bulk of race-specific kit. Built from a regenerated polyamide blend with moderate compression and a race-oriented chamois, they balance durability and performance for long-distance training and events.

Key Features

• Main fabric: The 73% regenerated polyamide and 27% spandex blend offers chlorine resistance and UPF 50+ protection so the shorts hold up for indoor pool swims and sunny training days.
• Adjustable drawstring: A secure, customizable waist fit keeps the shorts stable during vigorous cycling efforts and fast transitions.
• Accessible side pockets: Mesh nutrition pockets on each leg let athletes reach gels and chews while on the bike or run without fumbling.
• MK TRI 2.0 chamois: A multi-density pad shaped for the aero position provides targeted cushioning on the bike while remaining comfortable for the run.
• Ultra-thin leg grippers: Lightweight elastic leg cuffs conform to the thigh for a smooth fit without silicone irritation and improved flexibility.
• Flat locked stitching: Flat seams follow body contours to reduce chafing and increase durability through long rides and repeated washes.

Who It's For

These shorts are aimed at beginner to experienced triathletes who want a single pair to swim, bike and run in training and sprint to long-distance events. The combination of chlorine resistance, UPF protection and a race-oriented chamois makes them suitable for regular pool sessions plus outdoor brick workouts.

Athletes who prioritize maximum aerodynamic skin suits or those who require extremely thick cycling chamois for long road hours may prefer a dedicated cycling bib. Also, people who need large-capacity pockets for long rides should look for dedicated cycling shorts with larger storage.

Pros & Cons

Pros

• Comfortable, moderate compression fabric that resists chlorine and offers sun protection for multisport use.
• Convenient mesh side pockets provide easy access to nutrition during bike and run segments.
• MK TRI 2.0 multi-density chamois gives targeted cushion for aero bike position while still enabling a comfortable run.
• Flat locked stitching and ultra-thin leg grippers reduce chafing and improve long-distance comfort.

Cons

• Chamois is designed for triathlon aero position and moderate cushioning; athletes seeking very thick padding for extended road rides may prefer a dedicated cycling pad.
