Linen is a thin breathable fabric that's great for the summer. The one downside is because it's thin, it has more noticeable wrinkles than a wool blazer. It's not the end of the world because linen coats are worn in warm weather and casual wear doesn't need to be perfect. Just hang it up overnight and let gravity flatten out most of the wrinkles. Whatever stays is fine as long as you don't wear it for more serious events like a job interview.
