SLADEwrote a review of Castelli Estremo Gloves on December 31, 2014
Familiarity: I've used it several times
Disclaimer: I've NEVER found a pair of winter gloves that keep my hands warm. I get cold easily, especially my fingers and toes. After using these a number of times, my search for a dead-of-winter glove continues.
Pros: very well-constructed, good wind and water protection, secure velcro closure at the wrist, long cuff, good grip.
Cons: very bulky (but, strangely, still a good fit), not warm enough for me. On a 35-degree day, my fingertips were numb within the first hour.
