Can I adjust the fit at the bottom of the jacket, or does it just hang loose?
Yes — there's an adjustable stopper at the bottom hem specifically for a more secure, personalized fit, so you're not stuck with one fixed length if you prefer it cinched in or left looser.
Is this jacket breathable enough for all-day wear, not just intense workouts?
It should be — the fabric construction is built to promote airflow for all-day comfort during high-output activities, and it's described as soft-touch, thin, and lightweight, specifically noted as not feeling stuffy even in summer conditions.
Does the stretch fabric make this fit snug, or is it a more relaxed cut?
The fabric itself (88% nylon, 12% spandex) is stretchy, which gives it some give and flexibility during movement, though the product page doesn't specify whether the overall cut runs snug or relaxed — it's worth checking the size chart directly if you're deciding between a fitted or roomier feel.
Is there any functional difference between the Midnight Black and Trail Grey versions besides the color?
No — based on the product page, both colorways share the same fabric, construction, and features (diagonal zipper, stand-up collar, pockets, adjustable hem and sleeves), so the choice really just comes down to which color you prefer.
