My hands are very prone to eczema.  I use these mostly under a pair of vinyl gloves when I wash dishes or clean.  I also use these as driving gloves.  I wash them in hot water frequently.  They hold up great and don't shrink, or don't shrink enough to matter.  I only have to replace them when I lose them.

These are medium weight.  Strong enough to protect my hands, but light enough not to feel bulky.  They don't feel like they have nasty chemicals added to the cotton.
