Freewheel MTB Long-Sleeve
Outdoor Research
Outdoor Research brought their technical alpine pedigree into mountain biking with the Freewheel Long-Sleeve, a shirt built for trail riders who demand ruggedness and sun defense. Crafted from a recycled polyester fabric treated with UPF 30+ sun protection and an anti-odor finish, the Freewheel feels featherlight on the skin while holding up to the abrasive wear of backpack straps and trailside shrubbery. The patterning is distinctly cycling-specific. An extended drop-tail hem ensures your lower back stays covered when crouched in the attack position, while forward-rotated shoulder seams eliminate pressure points under heavy hydration packs. The sleeves are tailored to stay in place without sliding down your forearms, yet possess enough stretch to push up when temperatures climb. The material actively wicks moisture and dries exceptionally fast during pause breaks. While the fabric breathes well for a long-sleeve, it can still feel warm during dead-calm, humid summer afternoons where a short-sleeve would be preferable. The fit leans toward an athletic, trim profile; riders who prefer a baggy downhill look or who wear bulky hardshell elbow protection may want to size up. For all-mountain trail duties and mixed weather, it is a remarkably durable, refined layer. **Highlights** * UPF 30+ sun protection rating * Off-shoulder flatlock seams designed for backpack comfort * Generous dropped rear hem for complete coverage * Quick-drying recycled polyester construction * Active odor-control treatment **Watch-outs** * Athletic cut may require sizing up for bulky body armor * Long sleeves can get warm on windless, humid midsummer days

Phoenix (women’s) / Wesley (men’s)
Flylow
The Flylow Phoenix (women's) and Wesley (men's) jerseys are short-sleeve trail tops created for riders who favor a casual button-up or relaxed-tee aesthetic backed by serious heat-management tech. Flylow utilizes their proprietary Intuitive fabric—a lightweight polyester that sheds sweat rapidly and incorporates Polygiene odor control to keep the shirt wearable across multi-day weekend road trips. In motion, the fabric breathes freely and provides enough stretch to eliminate pulling across the upper back during aggressive cornering. The material feels noticeably soft, avoiding the clammy, synthetic plastic feel common in entry-level cycling shirts. Subtly placed underarm eyelets or mesh zones boost air circulation when riding slowly uphill, and the shirt dries out almost immediately once you hit the descent. The fit is casual and slightly loose, which is fantastic for airflow and post-ride socialization, but it can flap somewhat on high-speed downhill runs in gusty winds. The minimalist design also skips technical add-ons like zippered credit card pockets or integrated goggle wipes. However, as an understated, high-performing daily driver for hot-weather trail riding, it hits the sweet spot between style and technical utility. **Highlights** * Polygiene anti-odor treatment for multi-day use * Soft, breathable Intuitive technical fabric * Understated styling that works on and off the bike * Relaxed fit promoting airflow on hot climbs * Fast-drying and easy-care material **Watch-outs** * Loose cut may flap at higher downhill speeds * No zippered storage or accessory wipe patches
