Product Information

Full details

The Altura Kielder Progel Plus Undershorts are designed for adult male cyclists who tackle trail, gravel, or mountain bike terrains and require superior comfort for long days in the saddle. Featuring the brand's signature Progel pad technology and moisture-wicking mesh panels, these shorts deliver excellent temperature regulation and support. A notable caveat is that as an undershort, they are intended to be worn specifically beneath outer cycling garments rather than as a standalone outer layer.

FAQs

Can I wear these as regular cycling shorts?

No, these are designed specifically as an undershort. They lack the abrasion-resistant outer shell required for solo use.

What material are the shorts made from?

They are constructed from durable, high-wicking polyester with mesh ventilation panels.

How should I clean the Progel pad?

Machine wash on a gentle, cool cycle and allow to air dry. Avoid using fabric softeners as they can clog the wicking pores.

Will these shorts work with baggy MTB shorts?

Yes, they are designed to be compatible with almost any style of outer mountain biking or gravel shorts.

Are they suitable for road biking?

While they provide excellent cushioning, the pad is specifically tuned for the upright or trail-oriented posture of MTB and gravel riding.

Troubleshooting

Shorts shifting during a ride

Ensure the silicone leg grippers are in direct contact with your skin and that the outer shorts are not too tight, which can cause them to pull on the inner liner.

Moisture buildup

Check that the outer shorts worn over these are breathable; wearing non-porous synthetic materials over technical liners will trap heat regardless of the liner's performance.

Pros and Cons

Pros

  • Specifically designed for trail and MTB comfort
  • High-breathability materials manage moisture effectively
  • Silicone grips prevent shifting during movement
  • Sustainable construction with recycled pad fabric
  • Fitted design stays unobtrusive under other clothing

Cons

  • Not intended for use as standalone outer shorts
  • Requires specific outer shorts for full compatibility
  • Polyester material requires careful low-temperature washing

Setup, Compatibility & Care

To ensure peak performance, pull the Kielder Progel Plus Undershorts on firmly so the pad sits directly against the skin without folds or bunching. Because of the silicone leg grippers, they pair seamlessly with any loose-fitting MTB or gravel outer short. For care, wash the shorts in cold or cool water on a gentle cycle to preserve the elasticity of the fabric and the integrity of the Progel padding. Always air dry in the shade to prevent heat damage to the technical synthetic fibers.
