I bought the small size for my always cold girlfriend and they fit her skinny arms well without sliding down. I've had the same pair of Giordana arm warmers (M) since purchased for cycling in 1996-ish and they are still working great with no elastic issues and soft on the inside. Great product for warmth augmentation and very stuffable. Highly recommended item.
Very sturdy. I've used it a bit but can't comment on long term wear; I think its pretty cool so far. The Fork part pokes things pretty well but of course it has Spork limitations when spooning thin liquids. Well worth the price to have all your utensils in one indestructable place though.
This shoe is holding up nicely and is good for those who have not yet built up climbing feet. You cannot feel the holds like you would with slippers or a thinner shoe, but for me this is not necessarily a bad thing as my feet are very sensitive. I have climbed ~3 times a week at our University's wall and find the shoes very comfortable to wear continuously, although they need to be purchased rather small as they stretch appreciably.
