Short Answer: The Legendary USA Deerskin Insulated Mittens are the warmest motorcycle hand protection the brand makes. Built from 100% American Whitetail deerskin with 100g 3M Thinsulate insulation and a mitten design that keeps fingers together for maximum heat retention, these are purpose-built for below-30°F riding. Made in USA.
What Makes These Mittens Different From Any Other Winter Motorcycle Glove
Most riders shopping for winter motorcycle gloves are comparing insulated five-finger gloves against each other, upgrading from a fleece liner, or looking for something that actually works when the temperature drops below freezing. The Legendary USA Deerskin Insulated Mittens are a different category of answer.
A mitten design is thermodynamically superior to a five-finger glove for one simple reason: your fingers share heat with each other. When the temperature drops below 30°F and wind chill from highway speed compounds the cold, separate fingers lose heat far faster than fingers held together in a single chamber. The Legendary mittens are built around this principle — not as a compromise, but as the specific engineering choice for extreme-cold riding.
What separates these from cheaper winter mittens is the combination of materials. The outer shell is 100% American Whitetail deerskin — the same domestically sourced leather used across the entire Legendary USA glove lineup. Deerskin is half the weight of cowhide with dramatically more natural flexibility. In cold weather, leather that flexes easily is not a luxury — it is a safety requirement. Stiff hands and stiff gloves mean delayed throttle response, imprecise brake modulation, and reduced clutch feel. Deerskin stays supple in the cold in a way that full-grain cowhide does not.
The insulation is 100g 3M Thinsulate — 2.5 times heavier than the fleece-lined version in the Legendary lineup. Thinsulate traps heat without the bulk of traditional insulation, which matters when you still need enough dexterity to operate controls. The result is a mitten that is genuinely warm, not just marketed as warm.
Construction and Materials
Outer shell: 100% American Whitetail deerskin. Domestic hide, not imported split leather. Deerskin is naturally lighter and more flexible than cowhide, molds to the hand over time, and retains softness even after repeated use in wet and cold conditions.
Insulation: 100g 3M Thinsulate. This is the same insulation technology used in high-performance outdoor gear for decades. At 100g, it is rated for serious cold — not just cool autumn mornings. It is 2.5x the insulation weight of the Legendary fleece-lined glove option.
Mitten design: All fingers are housed together in a single chamber. This is the single biggest factor in warmth. When air temperature drops below freezing and wind chill from 65 mph highway riding is factored in, a mitten will keep hands warmer than any five-finger glove at equivalent insulation weight.
Double-layer palm: The palm receives a second layer of deerskin for durability and abrasion resistance in the grip zone. This is where leather wears first and where protection matters most in a slide.
Outseam stitching: Seams are stitched on the outside of the glove, not pressed against the palm. This eliminates interior ridges that create pressure points on long rides.
Thread: A&E industrial-grade thread. The same thread specification used throughout the Legendary USA lineup — rated for strength well beyond standard garment thread.

Who Should Buy the Legendary Deerskin Insulated Mittens
Cold-climate year-round riders. If you live somewhere that sees genuine winter temperatures and you ride anyway, these mittens are designed for you. Below-30°F riding with any five-finger insulated glove is a compromise. Mittens are not.
Touring riders in shoulder seasons. Early morning departures in spring and late-season rides in October and November push temperatures into ranges where most insulated gloves fall short. The 100g Thinsulate and mitten design create a significant margin of warmth that five-finger gloves cannot match.
Riders who run liner gloves. The Legendary mittens are sized to accommodate a lightweight liner glove underneath. Size up one size if you plan to use a liner. The additional warmth of a liner plus the mitten chamber plus the 3M Thinsulate makes this combination effective in conditions well below what most riders would consider rideable.
Adventure and dual-sport riders who face unpredictable conditions in mountain passes or high elevations where temperature drops fast and unexpectedly.
Sizing and Fit
Legendary USA gloves are sized XS through 2XL across most models. For the insulated mittens specifically: if you plan to wear a liner glove underneath, size up one size from your standard Legendary glove size. If wearing bare-handed, order your standard size. Deerskin stretches slightly with break-in — the glove will conform to your hand shape over the first several rides.
The mitten chamber is wide enough to accommodate all four fingers without compression, and the thumb is set at a natural riding angle for throttle grip. The elasticized or adjustable cuff is designed to seal against your riding jacket sleeve and prevent cold air from entering at the wrist gap.
Measure your dominant hand around the knuckles (not the thumb) to determine glove size. Legendary USA's size chart maps hand circumference in inches to glove size.
Caring for Deerskin Leather Mittens
Deerskin leather is naturally water-resistant but not waterproof. For riding in wet conditions, apply a leather conditioner or water-resistant treatment before use. After rides in rain or snow, allow the mittens to dry naturally away from direct heat. Do not machine wash. Condition the leather periodically to maintain suppleness, especially after prolonged cold-weather use where the leather may dry out.
Deerskin breaks in beautifully — the more you ride in these, the better they fit. Unlike synthetic insulated mittens that degrade over seasons, high-quality deerskin improves with use and proper care.
Frequently Asked Questions
Are motorcycle mittens safe to ride with?
Yes. Motorcycle mittens provide the same exterior leather protection as gloves and are a standard choice for cold-weather riding in Scandinavian and northern American riding communities. The Legendary USA Deerskin Insulated Mittens include a double-layer palm for abrasion resistance. The primary trade-off compared to five-finger gloves is reduced individual finger dexterity, which is offset at extreme cold temperatures where compromised hand warmth creates a far greater safety risk than slightly reduced dexterity.
Can I use my phone or GPS with these mittens?
The Legendary Deerskin Insulated Mittens are not a touchscreen-capable glove — the mitten design and insulation prioritize warmth over touchscreen functionality. For GPS or phone use, stop and remove the mitten or use a handlebar-mounted device with physical controls. If touchscreen capability is your priority, see the Legendary Aramid Lined Touchscreen Gloves.
How does 100g 3M Thinsulate compare to other insulation ratings?
3M Thinsulate weight ratings indicate insulation density. 40g is suitable for cool conditions. 80g handles cold weather. 100g — the rating in these mittens — is designed for serious cold, typically below 20°F ambient temperature. Combined with the mitten design's thermal advantage over five-finger gloves, the effective warmth rating is higher than comparable insulated gloves at the same 100g rating.
Should I size up for the insulated mittens?
If wearing a liner glove underneath, yes — size up one from your standard Legendary USA size. The mitten chamber has enough room for bare-hand use in your normal size, but liner gloves require the extra space. When in doubt, size up — the deerskin will conform to your hand with break-in.
What temperature range are these mittens designed for?
The Legendary Deerskin Insulated Mittens are designed for below-30°F ambient temperature. At highway speed, wind chill from 65 mph riding drops the effective temperature significantly. The 100g Thinsulate insulation and mitten design together create a warmth margin that standard insulated gloves cannot match in these conditions.
Are these mittens American-made?
Yes. The Legendary USA Deerskin Insulated Mittens are made in the USA using American Whitetail deerskin and A&E industrial-grade thread. Legendary USA is one of a small number of domestic manufacturers still producing leather riding gloves in America.
How do these compare to the fleece-lined Legendary gloves?
The insulated mittens use 100g 3M Thinsulate — 2.5 times the insulation weight of the fleece-lined Legendary gloves. They are designed for significantly colder conditions. If you ride primarily in temperatures above 40°F, a fleece-lined five-finger glove may be sufficient. For below-freezing riding, the insulated mittens are the correct choice from the Legendary lineup.
