We got one pair in a medium for myself and later a pair in size small for my daughter. Fit was a little tighter than expected but, I am guessing there is a very valid reason for this. Seems if they were to be loose in any way the protection wouldn't be as good.
I use my pair more in the kitchen and she uses her more for when she has the exacto knife out for cosplay crafting.
We have washed both pairs with out any issues. No shrinkage. I have deffinately tested these with the Ginsu knifes that I have slived my fingers without protection several times before. Zero cuts to date. Knock on wood.
To really put them to the test though, we tried to cut through them with both the Ginsu and the exacto knifes. NO CUTS .. Zero ..
We will forever be firm belivers in these cut resistant type gloves. Great invention for sure.
