Titicaca FR Shirt Flame Resistant Men's Cotton 6.5oz Lightweight Uniform Shirt

Are they unisex? Because I ordered my nephew a medium in men’s but sticker on package says women’s shirt. Just wanted to make sure it would fit him.

Can this shirt be dried in the clothes dryer? The tag only says Warm Machine Wash under 160deg.

Pocket depth? Need 6+ inches.

snaps or buttons?????????????
