A More Standard Fit
Updated sizing brings Vellum 2.0 closer to a standard glove fit.
Buying gloves online? Start with your hand measurements. This guide shows two common measurements—hand circumference and hand length—for people choosing everyday, outdoor or heated gloves.
The measuring technique is useful beyond Arcfomor. Each brand and model can have different sizing requirements, so follow the instructions and size chart for the gloves you plan to buy.
See where to place the tape in this 32-second silent tutorial by Arcfomor. Record your measurements, then compare them with the size chart for your chosen glove brand and model.
Hand size can differ slightly from left to right. Measure both hands and write down the circumference and length of each, using the same unit throughout. Follow your chosen brand’s guidance on which hand or measurement to use.
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.
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.

These measurements describe different parts of the hand and are not interchangeable. Check which measurements your chosen glove brand requests.
Measured around the widest part of the palm below the knuckles, excluding the thumb. Keep the tape snug without squeezing your hand.
The straight-line distance across the palm. It is not the same as circumference. If a size chart asks for palm width, follow that brand’s diagram for the exact measuring points.
Measured from the wrist crease to the tip of the middle finger. It helps determine whether the glove fingers will provide enough length.
Keep your circumference and length readings together with their units. Compare them with the chart for the exact gloves you want to buy. A size M in one brand may fit differently from a size M in another.
If your readings fall between sizes, point to different sizes or sit outside the chart, check that model’s fit notes or ask the brand for help. Liner gloves and insulated outer gloves can require different amounts of room.
Arcfomor makes heated gloves for different ways of spending time outdoors. Use the calculator and chart below to explore your size, then compare models such as Spider Silk and Feather for the activities you have in mind.
The calculator, chart and model advice below apply to Arcfomor gloves. For another brand, use that brand’s own size chart.
For Arcfomor gloves, select your model, choose inches or centimeters and enter the larger circumference and length readings from your two hands. Results are a starting point; check the selected model’s fit notes before ordering.
| Glove size | Hand circumference | Hand length |
|---|---|---|
| S | 7.9–8.5 in20.1–21.6 cm | 7.5–7.9 in19.1–20.1 cm |
| M | 8.5–9.1 in21.6–23.1 cm | 7.9–8.3 in20.1–21.1 cm |
| L | 9.1–9.6 in23.1–24.4 cm | 8.3–8.5 in21.1–21.6 cm |
| XL | 9.6–10.2 in24.4–25.9 cm | 8.5–8.7 in21.6–22.1 cm |
| 2XL | 10.2–10.8 in25.9–27.4 cm | 8.7–8.9 in22.1–22.6 cm |
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.
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 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.
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.
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.
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.
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.
Best for customers who want the thinnest dedicated heated liner to wear under an existing outer glove. Available in L and XL.

VELLUM 2.0
Vellum 2.0 combines a full goatskin exterior and lower-bulk palm with adjustable 7.4V heat. These heated work gloves are designed for horseback riding, barn chores, snow removal, firewood handling and other cold-weather tasks where grip still matters.
Updated sizing brings Vellum 2.0 closer to a standard glove fit.
Less bulk through the palm provides a closer feel on reins, handles and everyday tools.
The updated lining adds interior grip and helps reduce movement between the hand and glove.
Goatskin covers both the outer shell and palm. It provides a flexible grip and everyday resistance to surface wear during routine winter work without turning Vellum into a heavily padded glove.
The adjustable 7.4V heating system offers three heat settings. 3M Thinsulate is placed across the back of the hand, adding passive warmth without adding the same insulation thickness through the palm.
An internal waterproof membrane adds a moisture barrier for rain and wet snow. The gloves are not intended for immersion, and the battery connectors should remain dry. Touchscreen-compatible thumb and index fingertips support common phone controls.
Vellum 2.0 works best when you need active warmth without losing too much contact through the palm. Its construction makes it suitable for several common cold-weather activities:
Each set includes two rechargeable 7.4V 3000mAh batteries. Actual runtime varies with outdoor temperature, battery age and charging condition.
Choose Vellum 2.0 if you want a standalone rechargeable heated leather glove with more palm contact than a heavily padded snow glove. It is intended for riding, winter chores and light outdoor work rather than use as a thin glove liner.

Compare goatskin construction, fit, palm feel, weather limits and battery planning before choosing gloves for barn chores, snow removal or light outdoor work.
Clear answers about goatskin construction, fit, weather coverage, battery life, recommended uses and care.
Vellum 2.0 is designed for horseback riding, barn chores, snow shoveling, firewood handling and other light outdoor work. Its goatskin construction and slimmer palm suit cold-weather tasks that benefit from warmth and a closer grip.
Yes. Both the outer shell and palm are goatskin. Vellum 2.0 uses reduced palm thickness, while a grid-textured lining helps limit internal shifting. The thumb and index also support common touchscreen controls.
Vellum 2.0 is built with an internal waterproof membrane that adds a barrier against rain and wet snow. The gloves should not be submerged, and the battery connectors should be kept dry.
3M Thinsulate is placed across the back of the hand rather than throughout the entire glove. This adds passive warmth while helping maintain a lower-bulk palm.
Each pair includes two rechargeable 7.4V 3000mAh batteries. Approximate runtime is 2.5–4 hours on High, 4–8 hours on Medium and about 10 hours on Low. Actual runtime varies with temperature, battery age and charging condition.
Vellum 2.0 is available in S through XL, and its updated sizing is closer to a standard glove fit. Measure the circumference and length of both hands and use the larger measurements. Review the Arcfomor glove size guide and calculator before ordering.
The goatskin exterior provides everyday resistance to surface wear, making Vellum 2.0 useful for routine winter chores. It is not cut-resistant, chemical-resistant, impact-rated or certified protective equipment. Use task-specific protective gloves when the work requires them.
Remove both batteries and gently wipe the goatskin exterior with a soft, damp cloth. Do not machine wash, soak, bleach or tumble dry the gloves. Allow them to air-dry completely away from direct heat before reconnecting the batteries.
