Since the authors of the Radavist always have a camera on them, we’re going to try to provide more brief, succinct reviews of everyday products. This one’s been a staple in my car camping equipment for a while, though I never thought to use it on the bike. That is until I recently discovered that it fits in a Looney Bin.

The 32oz Insulated Howler by Miir keeps your beverages cold for a day (I’ve tested it) and hot for 12 hours, depending on how often you open it up. This thing is solid, made from stainless steel and consequently it’s a bit heavy but on a touring bike or townie bike, that’s kinda irrelevant, especially when having an icy cold drink at the top of a climb is of the utmost importance.

To give you an idea about it’s size, it’s 11″ tall, 3.5″ in diameter with a 2.5″ opening, complete with a flip top. You can fit it in a Loony Bin, a Widefoot Liter Cage, or any other “cargo cage.” It’s available in black or silver and in stock now at Miir.
