How to Measure Your Hand for Heated Gloves
A good fit helps heated gloves feel comfortable, warm consistently and maintain natural finger movement. Measure both hands, use the larger measurements and select the Arcfomor model you plan to wear.
Fit varies by model because Arcfomor gloves range from close-fitting heated liners and slim gloves to insulated snow, work and motorcycle styles. Use the chart below as a starting point, then check the fit guidance on the product page you plan to buy.
How to Measure Your Hand for Gloves
1Measure Both Hands
Hand size can differ slightly from left to right. Measure both hands and use the larger circumference and length when choosing your size.
2Measure Hand Circumference
Wrap a flexible measuring tape around the widest part of your palm, just below the knuckles. Do not include your thumb. Keep your hand relaxed and the tape snug, but not tight.
3Measure Hand Length
Measure from the wrist crease at the base of your palm to the tip of your middle finger. Keep your hand flat with your fingers naturally extended.
No flexible tape? Wrap a piece of string around your palm, mark where the ends meet and measure the string with a ruler.

Hand Circumference, Palm Width and Hand Length
These measurements describe different parts of the hand. For Arcfomor sizing, use hand circumference and hand length.
Hand Circumference
Measured around the widest part of the palm below the knuckles, excluding the thumb. This is the primary measurement used in the size calculator.
Palm Width
The straight-line distance across the widest part of the palm. Palm width is not the same as circumference and is not required by this calculator.
Hand Length
Measured from the wrist crease to the tip of the middle finger. It helps determine whether the glove fingers will provide enough length.

Available sizes: Ember is available in S–2XL. Dragonfly is available in L and XL. Other current Arcfomor glove models are available in S–XL.
If circumference and length indicate different sizes, use the larger measurement as your starting point. Fit can vary by model, so check the selected product page before ordering. If you are between sizes, choose the larger size unless that model recommends otherwise.
How Should Heated Gloves Fit?
Heated gloves should feel secure without squeezing the palm, limiting finger movement or creating pressure at the fingertips. A glove that is too loose can reduce dexterity and make it harder to grip tools, handlebars, ski poles or a phone.
Dragonfly Heated Liners
Dragonfly is Arcfomor's dedicated heated liner and is designed for a closer fit. It should not feel restrictive. When wearing it under another glove, make sure the outer glove has enough room for the liner, your fingers and the wrist battery area.
Spider Silk and Feather
These models can be worn on their own or layered under a roomier outer glove. They are thicker than Dragonfly, so check the available space inside your outer shell before using them as liners.
Insulated, Work and Ski Gloves
These gloves should leave enough room for natural finger movement without excess material at the fingertips. If you are between sizes, choose the larger size rather than relying on the insulation to stretch.
Motorcycle Gloves
Check palm comfort, finger length and access to the controls. The glove should feel secure when gripping the handlebar without pulling tightly across the knuckles or bunching at the fingertips.
If your measurements indicate different sizes: use the larger size as your starting point. For example, if circumference indicates M and length indicates L, start with L. If your measurements fall outside the available sizes for a product, contact us rather than forcing the closest size.
Choose a Glove Based on How You Plan to Wear It
Your recommended size is only part of the decision. Consider whether you need a dedicated liner, a versatile lightweight glove or a warmer everyday option.
Dragonfly
Best for customers who want the thinnest dedicated heated liner to wear under an existing outer glove. Available in L and XL.
View Dragonfly Heated Liners →Spider Silk
A versatile lightweight option that can be worn on its own or under a roomier outer glove. The flip-top design provides quick finger access.

Built for Warmth and Direct Finger Access
Small controls can be awkward through a winter glove. Spider Silk lets you uncover the thumb or index finger for direct contact while the rest of your hand stays covered. Close the covers again when you finish the task.
The 2.3mm build and adjustable 7.4V heat suit everyday use when you want less bulk than an insulated winter glove. It has more structure than a dedicated 0.5mm liner, but less passive warmth than a mid-weight insulated glove with the heat switched off.
Where Spider Silk Works Best
Winter Photography and Precision Tasks
Open a finger cover to turn a small camera dial or access a memory-card door, then close it again to reduce heat loss. The silicone palm adds grip on the camera body.
Commuting and Driving
The slim construction leaves less bulk around a steering wheel, keys or a transit card than a heavily insulated snow glove. For motorcycle riding, choose a glove designed for riding protection.
Winter Walks and Daily Errands
Handle a dog leash, keys or a phone without the bulk of a thick snow glove. Adjust the heat as your activity changes, and turn it down if your hands begin to sweat.
Layering in Colder or Wetter Conditions
Add a roomy outer glove when you need more insulation or weather coverage. Try both layers together: your fingers should bend freely, and the outer cuff should not press on the wrist battery.
Battery Runtime by Heat Setting
Each pair includes two rechargeable 7.4V 3000mAh batteries. Actual runtime varies with outdoor temperature, battery age, charging condition and the selected heat level.
- High
- 2.5–4 hours
- Medium
- 4–8 hours
- Low
- About 10 hours
Materials and Three-Layer Construction
Flexible Water-Repellent Outer Fabric
The polyester outer fabric uses a water-repellent treatment to help with light snow and brief moisture exposure while maintaining a flexible, lower-bulk feel. It is water-repellent rather than waterproof.
Low-Bulk Three-Layer Design
Spider Silk combines an outer shell, heating layer and inner lining without adding a separate bulky insulation layer. This construction supports its slim 2.3mm profile and easier finger movement, but it provides less passive warmth than an insulated mid-weight glove when the heat is turned off.
Silicone Grip on the Palm
The polyester palm includes silicone grip details to add friction on camera bodies, steering wheels, phones and other smooth everyday objects.
Flip-Top Cover Construction
Separate thumb and index-finger covers provide direct contact when fabric control is not precise enough. Buckle-style fasteners hold the opened covers out of the way during short precision tasks.
Compare Spider Silk with Other Heated Gloves
Spider Silk
2.3mm with flip-top finger accessChoose Spider Silk if you want a slim everyday glove and occasionally need a bare thumb or index finger for small controls. Compare the alternatives below if you need a dedicated liner, fully covered fingers or more passive insulation.
Dragonfly
Dedicated linerChoose Dragonfly when the lowest possible bulk is the priority and you need a 0.5mm heated liner beneath a compatible outer glove.
Feather
Slim fit without flip-topsChoose Feather when you want a 2.3mm slim-fit heated glove for standalone use or roomy layering but do not need flip-top finger openings.
Ember 2.0
Mid-weight standalone gloveChoose Ember 2.0 when you prefer more passive insulation and a mid-weight standalone design over the lower-bulk feel and flip-top access of Spider Silk.
Layering and Protection Limits
Fit and Layering
Spider Silk is available in S through XL and generally fits smaller than many standard North American winter gloves. Review the Arcfomor glove size guide and calculator before ordering.
When layering, choose an outer glove with enough room for the fingers, flip-top covers and wrist battery area without restricting movement.
Weather and Protection
The treated outer fabric is water-repellent rather than waterproof. Use a suitable outer glove when prolonged rain, wet snow or repeated moisture exposure is expected.
Spider Silk should not replace motorcycle gloves or task-specific protection designed for impact, abrasion, cuts or other workplace hazards.

Spider Silk Frequently Asked Questions
Find quick answers about finger access, sizing, battery life, weather protection and care.
What makes Spider Silk different from a heated glove liner?
Spider Silk is a slim standalone heated glove with a 2.3mm profile, adjustable 7.4V heat and flip-top access on the thumb and index finger. It provides more structure than a dedicated ultra-thin liner. It can be worn beneath a roomy outer glove, but it is not designed as a 0.5mm liner.
For a closer look at its thickness, fingertip access, heating coverage and everyday uses, read the Spider Silk 2.3mm daily comfort and hand wellness guide.
How long do Spider Silk batteries last?
Approximate runtime is 2.5–4 hours on High, 4–8 hours on Medium and about 10 hours on Low. Outdoor temperature, battery condition and the heat setting affect actual duration. Each pair includes two rechargeable 7.4V 3000mAh batteries.
Are Spider Silk heated gloves waterproof?
No. The treated polyester outer fabric helps with light snow and brief moisture exposure, but Spider Silk is water-repellent rather than waterproof. Use a compatible waterproof outer glove when prolonged rain, wet snow or sustained moisture is expected.
Can I use camera controls without removing the gloves?
Yes. Open the thumb or index-finger cover when a small dial or memory-card door needs direct fingertip contact. The rest of your hand stays covered. Secure the opened covers with their fasteners, then close them again when you finish.
Can I use Spider Silk heated gloves for typing and computer work?
Spider Silk can be used for computer work when the fit allows comfortable keyboard and mouse control. Only the thumb and index-finger covers open; the other three fingers remain covered. Test for missed keys, bunching fabric and wrist-battery pressure against the desk. Start on Low and reduce or switch off the heat once your hands are comfortable.
Can Spider Silk be worn under another glove?
Spider Silk can be worn beneath a sufficiently roomy outer glove when additional insulation or weather protection is needed. The outer glove must leave enough space for the fingers and wrist battery area without restricting movement. For the lowest-bulk layering option, choose a dedicated heated liner instead.
What size Spider Silk gloves should I order?
Measure the circumference and length of both hands, then use the larger measurements with the Fit & Size section above. Check the measurements for this model rather than relying on your usual glove size. If you plan to add an outer glove, allow room for finger movement and the wrist battery.
How should I clean and store Spider Silk heated gloves?
Remove both batteries before cleaning. Gently hand wash the gloves with mild soap, but do not soak, wring or twist them. Do not machine wash, dry-clean, iron or tumble-dry. Keep the battery connectors protected from moisture, and allow the gloves to air-dry completely away from direct heat and sunlight before reconnecting the batteries.
Disconnect the batteries during longer storage and keep the gloves and power components in a cool, dry place. Read How to Wash Heated Gloves Safely for the complete cleaning routine.
Can people with Raynaud’s phenomenon or arthritis use Spider Silk heated gloves?
Spider Silk provides adjustable warmth but is not a medical device and is not intended to diagnose, treat, cure or prevent Raynaud’s phenomenon, arthritis or any other condition.
People with reduced sensation, neuropathy, circulation concerns or joint conditions should ask a qualified healthcare professional whether heated gloves are appropriate, begin with a lower heat setting and check the skin regularly during use.
For condition-specific information, read the Arcfomor heated gloves and Raynaud’s phenomenon guide and the Arcfomor heated gloves for arthritis guide.
