Activating your gear?

Just wondering here, when you have enough shards to activate your gear for a match, does it stay activated for the entire match? Also, what about story episodes? I don’t think I’ve seen anything notifying me I can activate my gear in story sequences.

when you purchase gear it stays active for the whole match, story and pvp.

When you activate it you have it until the end of what ever mode you are playing. Story and pvp.
