Product Insights
The Fluid Comfort-Waist Ripstop Short 2.5" Length by I.FIV5 delivers unrestricted mobility and ventilation for intense activity, using a 2.5-inch inseam, wide leg opening, soft waistband, and side vents to eliminate restriction and reduce overheating. Its grid-stretch fabric offers snag resistance and four-way stretch, while the recycled nylon/spandex mesh reduces water and CO2 impact, meeting sustainability criteria. The main tradeoffs are a pocket that fits only small items like keys (not a smartphone) and a care routine requiring cold wash and hang dry to preserve the fit and Polygiene odor control, which allows multiple wears between washes.
Verified claims

- Movement cut
- 2.5-inch inseam and wide leg opening enable unrestricted lateral and high-knee movement.
- Value
- At $39.95 sale price, offers material comparable to a $198 short.
- Odor control
- Polygiene treatment lets the shorts go 4–8 days of mixed exercise before developing a musty odor rather than sharp body odor.
- Material
- Mesh: 89% recycled nylon, 11% spandex; reduces water 90% and CO2 80%.
- Certification
- Meets Simons Vision criteria for over 50% reduced-impact materials.
- Laundry additives
- Bleach and fabric softener degrade nylon strength and wicking performance.
- Washing method
- Cold wash inside out; hang dry to prevent shrinkage and protect reflective details.
- Wash frequency
- Polygiene treatment allows multiple wears between washes, reducing fabric wear.
- Moisture management

Product comparison
Compared within this brand.
| Fluid Comfort-Waist Ripstop Short 2.5" Length: Choose this if you want a very light, breathable 2.5-inch inseam short for wide-ranging movement, with a soft wide elastic waistband, side vents, a hidden waist pocket, and a fitted inner layer beneath the ripstop outer shell. Polygiene technology is claimed to eliminate odour and prevent bacterial growth, and reflective details add visibility. Note the brand describes it as one of the lightest shorts without specifying the comparison, and it is offered in sizes X-Small to Medium in Black, Brown, and Burgundy.[1,2,3] | Elastic Waist Loose Flowy Short 2.5" Length: Choose this if you want loose, flowy running shorts with a short 2.5-inch inseam, a wide elastic waistband, and a built-in breathable microfibre jersey panty. The lightweight stretch fabric (89% recycled polyester, 11% spandex, with an 89% nylon, 11% spandex mesh) is quick-drying with Polygiene® odour and antibacterial treatment, and there is an inner slit pocket plus a reflective logo. Sizes run from X-Small to X-Large.[4,5,6] | Perforated Lightweight Short 3" Length: Choose this if you want the brand's lightest, shortest short (3 inches) for running and high-intensity cardio, with fully perforated lightweight stretch fabric, a breathable built-in microfibre jersey panty, and Polygiene odour- and bacteria-fighting technology. The elastic waist has an adjustable inner drawstring, and reflective elements near the slits add visibility, in a relaxed black silhouette. Note there are no pockets, so it suits those who carry nothing on the run.[7,8] |
