Is a sun hoodie too hot for hiking?
A heavy hoodie can be hot, but ultralight sun hoodies are built for airflow and coverage. They work best when the fabric is light and the fit is not clingy.

Short answers for common search questions in this category.
Should hikers choose merino or synthetic?
Choose synthetic for fast drying and cooling. Choose merino or blends when odor control and repeated wear matter more than maximum dry speed.
Why does altitude change the shirt decision?
UV exposure generally increases with altitude, and shade can be limited above treeline. Higher coverage becomes more valuable even when the air feels cool.
