Nitrile, latex or vinyl
Nitrile is the strongest, resistant to many chemicals and causes no latex allergy: in workshops and industry it's the standard. Latex fits like a second skin and gives the most feel, but can cause allergic reactions in wearers and customers. Vinyl is the most economical and fine for short, clean tasks.
Mind thickness and certification
Thickness, expressed in mil or micron, determines how long a glove stays intact under rough work. If you want chemical protection, check whether the box carries an EN ISO 374 marking; a regular exam glove only protects against splashes. Never reuse disposable gloves: micro-tears aren't visible.
