As it happens, I recently spent the afternoon at an indoor rock climbing gym in San Francisco. It had been 10 years since I attempted such a feat, and despite my absence from the sport I didn’t fare too badly. Compared to the majority of the people in attendance, though, I was and still am a total newbie – there were guys sticking to walls and over hangs as if they were Spiderman.
And those are the people who I could totally see buying these somewhat ridiculous Crux Mugs. Each glass is affixed with an indoor rock climbing hold, otherwise known as an artificial rock (at least in my book). That said, it would seem that the intention of the Crux Mugs is to increase finger strength. However, you might want to reserve hot coffee and tea for a more traditional cup, and stick with soda, ice water and other things that won’t scold your inner thighs when the cup slips free from your fingers.
The Crux Mugs start at $16 a piece.
