Product Insights
The INNER SELF Micro-Perforated Shorts with 13cm built-in bike short (2.0 redesign) promise chafe-free comfort and lasting shape: bonded, heat-sealed hems on shell and liner eliminate seam ridges that rub or fray, a 74% nylon/26% spandex shell holds 95–98% stretch recovery wash after wash, and silicone grip dots on the liner stop ride-up without added compression, all in an ultralight AirGrid shell (95 gsm). Storage splits across dual side pockets, a gel slot, a rear zip pocket, and open liner patch pockets—but while the rear pocket secures valuables, the liner pocket won't close around a large iPhone, so a bouncing phone may need the zip pocket, and side/gel storage stays reachable rather than hidden like the Tracksmith Session's interior approach. The tradeoffs: sizing stops at XL (competitors reach XXXL), and care is specific—machine wash cold, hang dry, no bleach or tumble drying. At 90 CAD, it's a refined, lightweight short for those who fit the size range and accept open liner pockets for the sake of bond-and-grip stability.
Verified claims
- Phone pocket
- A verified reviewer says the liner fits a large iPhone but does not close; use the rear zip pocket if the phone cannot bounce loose.
- Carry layout
- Carry splits across side, gel, zip, and liner phone pockets; Tracksmith Session offers one rear zip plus three drop-ins.
- Version
- The current short is the 2.0 redesign released June 15, 2026, with new shell and liner, bonded hems, silicone grip and upgraded drawcord.
- Anti-chafing
- Bonded, heat-sealed hems on shell and liner leave no seam ridge to rub or fray the inner thigh.
- Liner stability
- Silicone grip dots on the 2.0 liner stop ride-up without added compression.
- Size range
- Sizes stop at X-Large; MUSCLE REPUBLIC COMPOUND INBUILT SHORTS 5-inch - LAVA SMOKE runs to XXXL.
- Shape recovery
- 74% nylon / 26% spandex holds 95-98% stretch recovery wash after wash.
- Seam durability
- Bonded hems on shell and liner stay flat, without a ridge to fray or pill.
- Drawcord
- 2.0 drawcord holds tie under movement and fine-tunes liner fit.
- Weight
- AirGrid shell at 95 gsm and the 2XU Aero lined short shell at 105 gsm differ by 10 gsm - same ultralight class.
- Pockets
- Side pockets and a zipped back pocket keep storage reachable, while the Tracksmith Session Shorts hide it inside.
- Construction
- Current 2.0 build bonds shell and liner hems and adds silicone grip dots in the liner.
- Fabric recovery
- AirGrid's nylon-spandex knit sits in the 95–98% stretch-recovery class.
- Size ceiling
- Only sizes S–XL are offered; MUSCLE REPUBLIC Compound reaches XXXL.
- Storage layout
- Gear-carry splits between dual side pockets and a dedicated gel slot on the shell.
- Pocket security
- Only the rear outer pocket zips; liner patch pockets stay open.
- Care
- Machine wash cold, hang dry, no bleach, no tumble drying.
- Wash durability
- Bonded hems avoid wash fraying; the high-recovery nylon-spandex shell resists bagging.
- Stretch recovery
- 74% nylon / 26% spandex shell retains 95–98% recovery over repeated wear and wash cycles.
