Daily Routines
Suitable for commuting, walking, errands, dog walking, light winter hikes and clearing snow from a vehicle or walkway.
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.

Find My Heated Gloves
Ottawa Nights is a mid-weight, five-finger glove for winter outings that involve both moving and waiting outdoors. Goatskin covers the palm, fingers and upper back of the hand, while polyester panels complete the shell. This gives you leather coverage around the areas used for gripping, with each finger free to move separately.
The passive insulation can carry part of the workload during active periods, allowing the heating system to be adjusted as movement, temperature and wind change. This makes Ottawa Nights useful when one outing moves between walking, commuting, photography and lower-motion periods outdoors.
Leather is concentrated across the palm, fingers and upper back of the hand—areas where contact, grip and structure matter most. Polyester is used across the remaining panels to keep those sections more flexible and reduce the all-leather feel of a heavier glove.
The DWR treatment on the polyester helps surface moisture bead and shed, while the membrane beneath the shell provides the main barrier against snow and normal winter moisture. This layered approach is designed for changing winter conditions rather than prolonged water exposure.
Suitable for commuting, walking, errands, dog walking, light winter hikes and clearing snow from a vehicle or walkway.
Separate fingers make it easier to handle a camera or phone than a mitten, although detailed controls may still require more precision than an insulated glove can provide.
A practical recreational option when a five-finger glove is preferred over maximum mitten warmth or a heavily padded gauntlet.
The mid-weight profile supports routine controls, but riders should account separately for the impact protection required by their activity.
Ottawa Nights keeps each finger separate, but it will not feel as precise as a thin liner or an uninsulated glove. The silicone palm pattern helps with general holding tasks, while touchscreen areas are intended for common actions such as answering a call, changing a map view or checking a notification.
Screen response can vary with the device, screen protector, weather and the amount of pressure used. Detailed typing or small camera controls may still be easier with an exposed fingertip.
High is useful when first warming the gloves or during lower-movement periods. Medium provides a balance for sustained cold-weather use, while Low can extend runtime when activity and passive insulation are already contributing warmth.
Runtime estimates are based on the included 7.4V 3000mAh batteries. Actual results vary with temperature, wind, battery condition, charge level and changes between settings.
Choose by overall weight, shell construction, finger access and primary activity—not voltage alone.

Ottawa Nights is a unisex, standard mid-weight 7.4V heated glove designed to be worn on its own. Its five-finger construction sits between a thin heated liner and a thicker insulated mitten.
Goatskin covers the palm, fingers and upper back of the hand, while polyester forms the remaining outer panels. 3M Thinsulate™ insulation is used across both the palm and back of the hand.
Ottawa Nights includes an internal waterproof membrane, and the polyester panels have a DWR treatment. These layers are intended to help with light rain, snow and road spray, but the gloves should not be treated as fully waterproof or submerged. Keep the batteries and connectors dry.
Estimated runtime is approximately 2.5–4 hours on High, 4–8 hours on Medium and up to about 10 hours on Low. Actual runtime varies with temperature, wind, battery condition, charge level and changes between settings.
Ottawa Nights is available in unisex S–XL and follows standard sizing. Measure both hands and use the larger circumference and length. If you are between sizes, use the larger size as your starting point. Review the Arcfomor glove size guide before ordering.
No. Ottawa Nights is a standard mid-weight glove designed for standalone use. It is not intended to fit underneath another glove.
Yes. Touchscreen-compatible areas are located on the thumb and index finger for common phone and navigation functions. Response may vary with the device, screen protector, weather and the precision required.
Ottawa Nights can be used for cold-weather cycling and E-bike commuting, recreational skiing, everyday driving and recreational cold-weather motorcycle riding. Because it does not include activity-specific hard-shell impact protection, it should not replace protective equipment required for track riding, professional racing or specialized work. For a closer look at handlebar feel and performance in cold riding conditions, read our Ottawa Nights heated cycling gloves field review .
Each package includes one pair of Ottawa Nights heated gloves, two 7.4V 3000mAh rechargeable batteries, one compatible charger and one storage bag.
Remove both batteries and spot clean the goatskin and polyester shell with a soft damp cloth and mild soap. Avoid soaking, full hand washing and machine washing. Do not tumble dry, iron or dry clean. Allow the gloves to air dry fully away from direct heat and sunlight before reconnecting the batteries.
