The 'airport security friendly' braces I bought arrived very quickly, and are perfect for the job... Heavy duty plastic clasps are performing well during my pre-flight testing, a little bulky, but not a problem, even when driving, and they don't scrape my leather driver's seat like the metal clasps on my old braces... If you don't like removing metallic items to go through airport checks I'd recommend this product as a good solution, but they're excellent also for everyday use, especially if you load up trouser pockets with tools, for instance... Recommended.
