Familiarity: I've used it once or twice and have initial impressions
These fit well, but go a size up so you don't tear them trying to get them on. Light and effective in wet Pacific Northwest Fall conditions, but wouldn't use them in heavy downpour. Sadly they are not durable. Had a tear on inside heel after second use from contact with bike crank while riding.
