I liked the older black nitril/latex gloves that HF no longer sells. Since I had to go shopping for new version I started with a box of the 9 mil. Tight on the palm while still a little baggy on the fingers. tight enough for mild discomfort. Still not that strong. They can tear easy and swell with many strong chemicals. Also not happy with only a 50 pack.
Last box, the light blue 5 mil. They fit better (same size). Not as restrictive. The thinner material acts like it is more durable to tears. I don't know how or why or even if it really is true. But I am doing better with the lighter ones. They are OK for incidental chemical contact, slightly better then the 9 mil version. But I would not be dunking my hands in nasty stuff with any of the gloves. Get real gloves for nasty work.
