What is the difference between seamless knit and cut-and-sew gloves?

Seamless knit gloves are machine-knitted in one piece from yarn - lightweight, flexible and low-cost, typically dip-coated on the palm for grip. Cut-and-sew gloves are panels of leather or fabric cut and stitched together - used where higher cut or impact protection, a rigid cuff, or leather durability is required, such as rigger and welding gloves.

Which glove coating should I choose - nitrile, PU or latex?

Nitrile offers strong abrasion and oil resistance and holds up well in rough industrial handling. PU (polyurethane) is thinner and gives better dexterity and tactile sensitivity for precision assembly work. Latex grips well on wet surfaces but has lower abrasion resistance and carries an allergy risk for some wearers, which is why nitrile has largely replaced it in industrial settings.

Do work gloves need EN 388 or ANSI/ISEA 105 certification?

It depends on the buyer's market and end use. EN 388 (mechanical hazards) and EN 407 (heat and fire) are the reference standards for gloves sold into the EU; ANSI/ISEA 105 is the equivalent for the US market. For general-purpose or promotional gloves, formal certification may not be required, but for gloves used in regulated industrial or PPE programmes, third-party test reports against the relevant standard are usually mandatory.

Nitrile-dotted seamless knit work gloves showing coated grip palms

Work and safety gloves look like a simple product, but each pair is an engineered piece of PPE: a shell construction, a coating chemistry and a certified performance rating, all matched to a specific hazard. Buying gloves on price alone without understanding these three layers is how brands end up with stock that fails on the factory floor or fails a compliance audit. This guide covers how gloves are built, what the coatings actually do, and how to read the safety standards printed on the cuff.

How gloves are constructed

Seamless knit: knitted in one piece on a glove-knitting machine from cotton, polyester, nylon or blended yarn. Lightweight and flexible with no seams to chafe - the base for most dip-coated work gloves.
Cut-and-sew (leather or fabric): panels cut from split leather, canvas or fabric and stitched together. Used for rigger gloves, welding gloves and anything needing a rigid cuff, reinforced palm or higher cut resistance than a knit shell can offer.
Dipped/moulded: a former is dipped directly into liquid latex, nitrile or PVC to build the glove without a textile shell at all - common for chemical-handling and disposable gloves.
Liners: fleece, thermal or terry liners are added for cold-store and winter gloves, either knitted integrally or inserted as a separate layer.

Coatings: what each one is actually for

The coating is where grip, durability and chemical resistance are decided. Palm coverage (palm-only, 3/4, or full-dip) and coating thickness change the trade-off between dexterity and protection.

Nitrile: the industrial default - strong abrasion and puncture resistance, good oil and grease resistance, holds up in rough handling. Available foamed for grip or smooth for a firmer shell.
Polyurethane (PU): thin, close-fitting and highly tactile - the choice for precision assembly and electronics handling where finger sensitivity matters more than abrasion resistance.
Latex: excellent wet and dry grip at low cost, but weaker abrasion resistance than nitrile and a known allergy risk for some wearers, which has pushed many industrial buyers toward nitrile instead.
PVC: resistant to a broad range of chemicals and cheap to produce, but stiffer and less breathable - typically used for gloves with heavier dip coverage in wet or chemical environments.

Reading the safety standards

EN 388 (mechanical hazards): the EU standard for abrasion, cut, tear and puncture resistance, shown as a set of ratings next to a shield icon. It is the number most buyers check first for general industrial gloves.
EN 407 (heat and fire): covers flammability, contact heat, convective heat, radiant heat and contact with molten metal - relevant for welding and foundry gloves.
ANSI/ISEA 105: the US equivalent to EN 388, rating cut, puncture and abrasion resistance on its own scale - buyers shipping into the US typically need gloves tested and labelled against this standard, not EN 388 alone.
Chemical resistance (EN 374): tested against specific named chemicals with a breakthrough time - a glove is only "chemical resistant" to the chemicals it was actually tested against.

Common mistakes when sourcing gloves

Assuming one coating fits every task: a nitrile glove built for handling sheet metal is the wrong choice for fine assembly work, and vice versa. Specify the task, not just "work gloves."
Ignoring size distribution: gloves that run small or large across a size range cause returns and complaints even when the material is correct. Confirm the size chart against a physical sample before bulk.
No test report on file: if a certification level is claimed, ask for the third-party test report referencing that batch or fabric construction, not a generic supplier claim.
Overlooking seam and cuff finishing: for cut-and-sew styles, loose stitching at the thumb crotch and an unfinished cuff edge are the first points of failure in the field - inspect these on the pre-production sample.

Mesh Apparel produces seamless knit, coated and cut-and-sew leather gloves alongside its apparel lines, from assembly and rigger gloves to insulated winter styles. If you have a hazard profile and target market in mind, we can recommend the shell, coating and standard that fits before you commit to a sampling run.

Frequently asked questions

Seamless knit vs cut-and-sew - what's the difference?

Seamless knit gloves are knitted in one piece and dip-coated for grip - light and flexible. Cut-and-sew gloves are stitched from leather or fabric panels, used where higher cut protection or a rigid cuff is needed.

Nitrile, PU or latex - which coating should I pick?

Nitrile for abrasion and oil resistance in general industrial handling; PU for dexterity in precision assembly; latex for wet grip, with an allergy trade-off that has pushed most industrial buyers to nitrile.

Do I need EN 388 or ANSI/ISEA 105 certification?

Required for regulated PPE use; EN 388/EN 407 for the EU market, ANSI/ISEA 105 for the US. Always ask for the batch-specific test report, not just a claimed rating.
