Scott L.wrote a review of Metolius Belay Glove on June 9, 2014
After reading reviews here (thanks, everyone) and elsewhere, I purchased small and medium sizes of black Metolius belay gloves. I actually plan to use them on longer rappels, and maybe some other rappels as well.
I recognize the advice to squeeze in the smaller size, but that didn't work for me. I could get my hand in small size, but the fingers were a tad too short, and that was uncomfortable. Also, the small size didn't extend down the hand as far as it should have, stopping just at the edge of the ulnar styloid (that's the bony "knob" on the outside of the wrist). BTW, I do not have long, "spidery" fingers (as a guitarist, I've seen plenty of long spidery fingers, and I ain't got them).
So I went with the mediums, which fit the length of my fingers nicely and extend down to cover about 1/2 the ulnar styloid. As one would expect, cowhide is stiffer and, important to me, tougher (than goatskin).
I am going to wear them around and practice "making a fist" to break them in. I recognize that one must be cautious in using gloves for rappelling. I do know that last time I went canyoneering, I developed a blister on my middle finger of my (non-brake) hand, and that the 3/4 fingerless glove I was wearing didn't protect the middle section of my finger.
BTW, the 3/4 climbing gloves do not extend far enough up the digit to protect three-quarters of your finger. Thus it is a misnomer to call them "three-quarters" gloves, and at any rate the finger naturally divides into "thirds" because of the two joints (PIP--proximal interphalangeal and DIP--distal interphalangeal).
