Every few weeks a buyer tells us their latex-coated gloves "fell apart for no reason," and when we ask what the crew was handling, the answer is almost always the same: something oily. Latex is a natural rubber, and petroleum products attack it — the coating swells, softens, and starts shedding within days. The crew didn't get a bad batch; they got the wrong coating. Microfoam nitrile and crinkle latex are the two workhorse palm coatings on general-purpose coated work gloves, and choosing between them is a five-minute decision once you know what each chemistry tolerates. Here is the sequence we walk buyers through at G & F Products R&D.

Two coatings, two different chemistries

Crinkle latex is natural rubber dipped over a knit liner — usually 10- or 13-gauge cotton/poly — and textured during curing so the surface wrinkles. Those wrinkles act like tire tread: they channel water away from the contact patch and give latex its characteristic wet grip. Latex is also the most elastic coating we work with, so it flexes with the hand and stays soft in cold weather.

Microfoam nitrile is synthetic rubber foamed with thousands of microscopic open cells, typically dipped over a thinner 15-gauge nylon/spandex liner. The open-cell structure does two jobs: it wicks light oil off the contact surface the way a sponge lifts liquid, and it keeps the coating thin and breathable, so tactility stays close to bare-hand. Nitrile is also chemically indifferent to oils, greases, and most hydrocarbons — the exact substances that destroy latex.

Step 1: Identify what's actually on the surfaces you handle

This single question settles most cases. If the work involves oil, grease, fuels, or lubricated parts — engine work, machining, fastener handling, anything with cutting fluid — choose microfoam nitrile and stop here. Latex degrades on contact with petroleum products, and the foamed nitrile cell structure actively manages light oil films instead of skating on them. If the work is wet with water only — wet lumber, irrigation lines, fish boxes, rainy-day material handling — crinkle latex earns its keep, because the wrinkle texture displaces water better than foam does. If the work is dry, either coating grips fine, and the next four steps become your tiebreakers.

Step 2: Rule latex in or out for allergy exposure

Natural rubber latex causes Type I allergic reactions in a small but real share of the population, and sensitization gets worse with repeated exposure, not better. If gloves are issued from a shared bin, if you can't survey every worker, or if the gloves contact food or people who handle food, the cautious spec is nitrile — it's synthetic and carries no latex proteins. This is why we steer institutional buyers (schools, food distribution, healthcare-adjacent facilities) to microfoam nitrile by default even when latex would grip equally well. A coating choice shouldn't create an HR problem.

Step 3: Match the coating to the dexterity the task demands

Pick up the smallest object the job involves and be honest about it. Microfoam nitrile on a 15-gauge liner is the thinner, more tactile package — small fasteners, electrical connectors, parts sorting, and assembly work all favor it. Crinkle latex is a thicker, more cushioned coating on a heavier liner; it trades fingertip feel for padding and works fine when the smallest thing you grab is a shovel handle, a brick, or a length of pipe. If workers keep pulling gloves off to do the fiddly parts of a task, the coating is too thick for the task — and a glove that's off the hand protects nothing.

Step 4: Weigh durability, temperature, and storage conditions

In our abrasion testing, foam nitrile palms generally outlast crinkle latex on rough, dry surfaces like brick, lumber, and concrete block — the foam wears down gradually while latex tends to shed in flakes once the surface tread rounds over. Latex pulls ahead in cold: it stays elastic well below freezing, while nitrile stiffens noticeably as temperatures drop. Storage matters too. Latex degrades under UV and ozone exposure, so gloves that live on a truck dashboard or an outdoor rack will harden and crack months sooner than the same pair kept in a drawer. Nitrile shrugs off both. For mixed conditions, this is also where mechanics-style gloves enter the conversation — we covered those trade-offs in our buyer's guide to mechanics gloves.

Step 5: Run a one-week side-by-side trial before bulk-buying

Coating choice is cheap to test and expensive to get wrong at the pallet level. Issue one sample pair of each coating to the two or three people who use gloves hardest, and have them swap mid-week. Ask three questions at the end: which pair needed fewer re-grips on the job's slipperiest object, which pair came off the hand more often for fine tasks, and which palm shows more wear. The answers almost always converge on one coating. Inspect the trial pairs before deciding — the wear patterns tell you as much as the wearers do, and the same checks we use for spotting a glove that's lost its rating apply here.

Where each coating usually lands

After enough of these conversations, the pattern is consistent. Microfoam nitrile wins for mechanics, assembly, warehouse, and any oil-adjacent work — and it's the coating we put on most of our garden glove lines, because breathability matters over a long afternoon of dry digging and pruning. Crinkle latex wins for masonry, landscaping in wet conditions, demolition, and cold-weather outdoor work where its elasticity and water-channeling texture do their jobs. Neither coating is a cut rating, a chemical-splash barrier, or a heat barrier — they're grip and abrasion layers over a knit liner, and they should be specced as exactly that. If your use case doesn't fit cleanly into either column, the surface-condition question in Step 1 is the one to trust; the G & F Products team has watched it predict the right answer for forty years.
