Leather or coated knit work gloves: which should I buy?

It depends on the job. Across the reviewers we read, full-grain or split cowhide leather (Wells Lamont, Ironclad Ranchworx) wins for abrasion, puncture protection and fencing/ranch work, while thin nitrile- or foam-coated knit gloves win for dexterity, grip on light oils and all-day comfort. Leather lasts longer in heavy abrasion but stiffens when wet; coated knits are cheaper and more breathable but wear through faster.
