This is a soft-sided thimble with reinforced tip that is very comfortable to wear and use. It has vents on the top side that help keep fingers cool. The deep dimple in the reinforced tip are deep and easily hold onto the needle and make pushing much easier. this thimble helps with hand fatigue. It’s also a very durable thimble. I’ve been using the same one for almost 2 years. It’s the most comfortable thimble I’ve used. I wear a size Medium on my middle finger that is approximately 1 1/2” around.
