The Best Mittens for Cold Weather - My Favorite Mittens Ever!
Features that Make the Best Mittens for Cold Weather:
A long and wide gauntlet cuff.

A wide and long gauntlet goes a long way to keep hands warm!
A roomy hand section.
An anatomical curve.

It's not always easy to find, but this is one feature I love. The biggest advantage of this to me is that it reduces hand fatigue that can occur when you have to work too hard against the loft of the insulation to let your hand curve naturally or when you are doing an activity that requires you to grip something for a period of time (handlebar, shovel, ski pole for example). A slight curve to the mitt is much more comfortable to wear and reduces hand fatigue.
Extra insulation over the hand
Soft, thin and fast-drying liner.

In the hand area, there is a thin brushed fabric/fleece while the gauntlet section is lined with a light nylon (for ease in sliding over jacket sleeves). Polartec Fleece Lining is a good choice for the hand area (fleece side against your skin). Moisture-wicking and fast drying is important to keep dampness from sweat at bay, especially if you are camping or don't have a good method for drying out your mitts after wear.
The benefit of making your own mittens for cold weather is that you can choose where you put the insulation, and custom design for your needs, from fabric to design.
A pliable outer fabric.
My final tip. (Its important!)
We have a new PDF pattern for Wristlet Hand Warmers, that incorporates a pocket for a hand warmer over the wrist. This warms the blood going to the fingers!
A couple of suggestions: Choose a cozy fabric with a smooth surface such as Thermal Flex, Polartec Power Stretch or Northern Lite so your mitts and long-sleeves slide overtop easily. They should fit closely but should not constrict. Add a pocket on the inside of the wrist for a hand warmer - more convenient than bunched up in your palm!

Fabric Options
While there are likely hundreds of fabric combinations to try, here are a few to consider for making the best mittens for cold weather.
OUTER FABRIC:
When making your own mittens for cold weather, these technical shell fabrics provide protection from the elements. Stretch is not an important factor in the shell, so if choosing Polartec Neoshell both stretch and non-stretch styles are fine.
- Polartec Neoshell no stretch
- Polartec Neoshell with stretch
- Polartec Power Shield Pro
- Nike Shells
- Aluminum Back Shell
- HyVent DT
LINING FABRIC:
When choosing or making the best mittens for cold weather, the lining must serve the purpose of keeping your hands dry. Therefore it should be moisture-wicking. It also should add some warmth, but the most warmth will come from the insulation layer.
INSULATION FABRIC:
Mitten PacksWe recommend Primaloft Gold when available, as well as Primaloft Silver as the best runner up to Gold. If you are making mittens for chilly but not extreme cold, you can use other lofty fabrics to insulate, such as Polartec High Loft. It is technically an outerwear fabric but does work well for many winter climates. We often include High Loft as the insulating layer in our Mitten Packs, which are intended for those learning to make mittens.

We love to help with fabric choices, which is why we have a Facebook Group. If you ask in our group, be specific about where you live (climate), what you will be using the mittens for. We will try to make suggestions will help with your project. We prefer questions be asked in the group where others can learn from the questions asked as well.
