What is the warmest insulation for work gloves? Fleece, foam, acrylic, wool, Thermosock and Thinsulate, as MCR Safety ranks them
MCR Safety’s winter glove guide ranks its six linings on a good, better, great scale, in this order from least to most: fleece (brushed cotton or cotton blend), foam, acrylic (string, brushed or terry knit that captures body heat), wool, Thermosock (MCR Safety’s own high-loft synthetic fiber, for weight-to-warmth) and Thinsulate (3M’s synthetic microfiber, in 40, 100 and 200 gram weights, for warmth-to-thickness). The warmest lining in the line by that ranking is 200 gram Thinsulate, and the thickest warm lining is a high-loft pile; what makes a glove warm on the job is the lining together with a windproof or waterproof shell, because a wet or wind-cut lining loses its loft. The only published cold rating is EN 511, which MCR Safety states as a contact cold level (1 or 2) on its insulated knits; the standard also rates convective cold and water penetration, and MCR Safety does not publish those digits.
MCR Safety 32013T Drivers Gloves, Cowhide, Competitive Value C+ GradeThinsulate-lined, the warmest lining on MCR Safety’s scale (MCR Safety data)Why “warmest” depends on the shell as much as the lining. Insulation works by trapping still air; wind drives the air out and water replaces it with something that conducts heat many times faster. That is why MCR Safety pairs its Thinsulate and Thermosock linings with a Hipora waterproof bladder on the leather and synthetic winter styles, and its acrylic-lined knits with a full or three-quarter HPT (hydropellent) coating for wet work. A thick acrylic knit with a fully coated palm can be warmer in slush than a Thinsulate leather with a wet back. The EN 511 contact cold level on the knits is the one test figure available: how long the palm keeps a cold plate from pulling heat through, level 1 to 4. Dexterity is the other side of the trade: 200 gram Thinsulate is the warmest and the thickest, and a 40 gram Thermosock liner the thinnest.
The linings, in MCR Safety’s order
From its winter glove guide, least to most warm, with what each one is.
What the product pages state, and how to read them
- Lining: the field names the lining as MCR Safety lists it (acrylic, fleece, foam, merino wool, Thermosock, Thinsulate C40, C100 or C200 gram, jersey, pile).
- Shell and coating: a full HPT coating is listed for liquid protection, a palm coating for breathability; MCR Safety lists “Insulated” in the features field on every winter style.
- EN 511: the contact cold level MCR Safety states (1 or 2 on the knits, 3 on one mechanics style); the convective and water digits are not published, so the guide does not infer them.
- ANSI/ISEA 105: the cut, abrasion and puncture levels carry over to the winter version; a Ninja Ice or Cut Pro winter style lists its cut level like the summer glove.
- Leather winter gloves: fleece, pile, Thermosock or Thinsulate inside cowhide or pigskin, with the grade MCR Safety prints; the bladder is listed where there is one.
Portwest’s linings
Portwest names an acrylic or brushed-acrylic lining on its Portwest Thermal Protection Gloves and Portwest Aqua Gloves winter knits, a fleece lining on the A540 welding gauntlet and a thermal lining on the A753 winter mechanics glove; it publishes no gram weight for the insulation, so the band shows the lining name and the EN 511 contact-cold level as Portwest states them.
Portwest product pages and US data sheets for the styles shown (documents.portwest.com), fetched Nov 7 2026The liners Radians names in its winter gloves
Radians’ winter glove article names three features it looks for: a water-repellent outer coating or material for water and wind resistance, an insulating liner that traps air and wicks moisture, and comfort with a good fit. It lists the liners it uses, 3M Thinsulate (microfibers that trap body heat while moisture escapes, allowing less bulk and better dexterity), thermal liners, quad layers, 100-gram microfleece, 7 gauge acrylic terry liners and inner shells, acrylic thermal liners and fleece, and states the choice depends on the temperature, the application and the fit wanted. On fit it states that a tight glove restricts circulation and raises sweating, making hands colder, that a loose glove can catch in machinery and cuts dexterity and grip, and that an extended gauntlet cuff with hook and loop closure keeps snow out. The Lining and Insulated lines on each Radians winter glove page name the liner.

Are mittens warmer than gloves, and why are my hands cold even with gloves?
A mitten keeps the fingers together in one air space and has less surface for heat to leave through than five separate fingers, which is why the heaviest cold-weather handwear is a mitten; the cost is dexterity, and work gloves are gloves for that reason. Hands that stay cold inside a glove usually have one of the causes the sources name: a wet lining (Radians: a water-repellent outer is the first feature it looks for, because water conducts heat away many times faster than air), wind through the shell, a glove so tight it restricts circulation (Radians: a tight glove restricts circulation and raises sweating, making hands colder) or a lining compressed by a glove one size too small, and sweat from a glove that cannot breathe. The fix is in the same list: a windproof or waterproof shell over a lining with loft, sized to leave the insulation uncompressed, and a wicking liner changed when damp.
What gloves are rated for hands with poor circulation, and is 50 degrees cold enough for gloves?
No glove is rated for a medical condition; the published cold rating is EN 511 (contact cold, convective cold, water penetration), and a hand that runs cold wants the higher contact-cold digit and the waterproof 1, a lining with loft (Thinsulate 100 to 200 gram or high-loft pile on MCR Safety’s scale) and a fit that does not squeeze. At 50 °F (10 °C) a dry hand working hard usually needs no insulation; a hand that is wet, still or in wind does, and the EN 511 convective-cold digit is the measure of a glove against moving air.
Answers from the sources named above and in the byline.Questions people ask
What is the warmest material for gloves?
On MCR Safety’s scale, Thinsulate and Thermosock rank highest (“great”), then wool and acrylic (“better”), then foam and fleece (“good”); 200 gram Thinsulate is the heaviest lining in its line. A waterproof or windproof shell decides whether the lining keeps its warmth.
Is Thinsulate warmer than fleece?
By MCR Safety’s ranking, yes: Thinsulate is listed for its warmth-to-thickness ratio and fleece as a brushed cotton lining with some thermal property.
What does 100 gram Thinsulate mean?
The weight of the insulation per square meter; MCR Safety uses 40, 100 and 200 gram, and the heavier weight is the warmer and thicker glove.
What is the EN 511 rating on a winter glove?
A three-digit European cold rating: convective cold, contact cold and water penetration. MCR Safety publishes the contact cold level (1 or 2 on its knits); see the EN 511 guide for the full code.
Are acrylic-lined gloves warm?
MCR Safety ranks acrylic as “better”, between fleece and wool; it is the lining on most of its insulated coated knits, where the coating keeps the lining dry.
Do thermal gloves keep your hands warm?
The lining traps body heat and the shell keeps wind and water off it; how well is measured by EN 511, the only published cold rating (convective cold 0 to 4, contact cold 0 to 4, water penetration 0 or 1). MCR Safety states contact cold levels of 1 or 2 on its insulated knits; Portwest prints the full three-digit EN 511 code on its winter gloves.
What are good waterproof gloves for snow?
A winter glove whose EN 511 code ends in 1 (no water penetration in the timed test) with a full nitrile or PVC dip or a waterproof bladder, over a lined knit. Portwest’s winter gloves list the EN 511 code and the coating on each page; MCR Safety lists a full HPT coating for liquid protection on its insulated styles.
Are 3M Thinsulate gloves good, and do they work?
Thinsulate is 3M’s synthetic microfiber insulation, which MCR Safety ranks at the top of its lining scale (“great”) for warmth-to-thickness in 40, 100 and 200 gram weights; the glove’s EN 511 contact cold level on the product page is the only published measure of what it does, and the shell has to keep the lining dry for it to hold.
What are the warmest liner gloves?
By MCR Safety’s ranking, liners in Thermosock or Thinsulate over wool and acrylic over fleece; a liner is sized under the shell without compressing, because compressed insulation loses loft. The glove liners guide covers sizing over a liner and the EN 511 rating thermal liners carry.
What is the warmest lining for leather gloves?
MCR Safety lines its winter leather gloves with fleece, pile, Thermosock or Thinsulate inside cowhide or pigskin, and ranks Thermosock and Thinsulate highest; one lined mechanics style states EN 511 contact cold 3. Wet leather conducts heat away faster than dry, so the waterproof bladder MCR Safety lists on some styles is part of the warmth.
Do leather gloves keep you warm in winter?
Only as warm as the lining inside them: unlined leather carries no cold rating and goes cold when wet. The leather winter gloves in the band show the lining MCR Safety names (fleece, pile, Thermosock, Thinsulate) and the EN 511 contact cold level where MCR Safety states one.
Is it worth buying heated gloves?
Heated gloves and heated liners are battery-warmed garments, not rated PPE: no standard rates their warmth, the run time is the manufacturer's claim at a setting, and the battery pack sits at the wrist. The insulated gloves on this page are rated by their lining (gram weight of Thinsulate, lining type) and by EN 511 contact-cold levels, which are test results. For a crew, a windproof, waterproof shell over a high-loft lining is the published answer in MCR Safety's and Radians' winter guides; heated gloves are a comfort purchase outside the ratings.
What gloves are warmest for extremely cold hands?
By the MCR Safety ranking on this page, 200 gram Thinsulate and high-loft pile linings are the warmest, inside a windproof or waterproof shell so the lining stays dry and keeps its loft. EN 511 is the only published cold rating: level 2 contact cold on most insulated knits here, 3 on one mechanics style. For work below freezing with wet hands, the full-dip coated winter gloves (PVC or nitrile over a thermal liner) keep the lining dry; the cold stress guide covers the exposure limits.
Are mittens warmer than gloves?
Yes, for the same insulation: fingers share one air space and lose heat through less surface. Work gloves give up that warmth for dexterity; the insulated work gloves here are rated by their lining and EN 511 figures.
Why are my hands cold even with gloves?
A wet or wind-cut lining, a glove tight enough to restrict circulation (Radians’ winter article names it), compressed insulation from a size too small, or sweat the glove cannot move. A waterproof shell, loft, a wicking liner and the right size address each.
What kind of gloves are good for hands with poor circulation?
No glove carries a rating for it; the published measures are the EN 511 contact and convective cold digits and the lining weight, and the fit should not squeeze. The lining ranking on this page and the EN 511 guide are the figures to use.
Is 50 degrees cold enough for gloves?
For a dry, active hand usually not; for a wet, still or wind-exposed hand yes, and the EN 511 convective-cold digit measures a glove against moving air. The task decides, not the thermometer alone.
Do heated gloves work well, and how do you wash heated gloves?
A heated glove is a battery-warmed garment with no PPE rating; its warmth and run time are the manufacturer’s claims at a setting. Washing follows that manufacturer’s instructions, usually with the battery removed; none is listed on this site.
Which glove lining is the warmest?
By MCR Safety’s ranking, Thinsulate (40, 100, 200 gram by weight) and Thermosock, then wool and acrylic, then foam and fleece; 200 gram Thinsulate is the heaviest lining in its line. Radians names Thinsulate, microfleece and acrylic terry liners.
What are the warmest waterproof gloves?
The ones whose EN 511 code ends in 1 (no water penetration) over the heaviest lining: Portwest prints the full code on its winter gloves, MCR Safety pairs Thinsulate with a Hipora waterproof bladder on its leather and synthetic winter styles.
