The Q36. 5 Dottore Hybrid Vest builds its shell from a body-mapped nylon and elastane blend, holding a regular fit that layers cleanly whether it's the only thing cutting the wind or one piece of a colder kit. A mesh rear panel keeps the back breathable, so the vest doesn't turn into a sweat trap once the temperature climbs. What Our Gearhead(R) Experts Are Saying:"I've pulled this on for a chilly morning start in spring and a genuinely cold fall descent, and it's held up both times without needing a different layer underneath."
