The Bluegrass Bold is one of few pisspot lids to offer a proper adjustable cradle to tailor the fit. The dial at the rear makes it easy to get a proper, snug fit and, should you need to do so, it can be adjusted on the fly with just one hand.
The ABS outer shell and EPS liner are tough too. It also has a pleasingly low price. The minimal padding is okay for a short amount of time but after a while the narrow pad that sits on your brow gets a little uncomfortable. A bigger pad should solve this though and some internal channelling would help to promote better airflow too.
