Deux par Deux TEKNIK winter mittens in Black, sizes 2/3 to 15/16

Six age bands running 2/3 to 15/16. One model covers the whole range, so each winter the choice is a size rather than a new product.

Deux par Deux describes them as having a waterproof zippered pocket that doubles as a vent, Cordura®-reinforced fingertips, a pre-curved ergonomic fit, a rubberized palm and a brushed microfiber lining. The maker also publishes performance figures: a 15,000 mm polyurethane-coated fabric, 15,000 g/m²/24h breathability, fabric tested to 30,000 abrasion cycles, a lining it rates to −30 °C / −22 °F, and a fluorocarbon-free BIONIC-FINISH®ECO water-repellent finish it states is free from PFAS, PFOS and PFOA.

Every figure in that paragraph is Deux par Deux's own published claim, quoted with the maker named. Habier has tested none of them and makes no waterproof, breathability or temperature promise of its own.

Sized by age, not by hand. Deux par Deux publishes no hand measurement for these mittens, and we will not invent one. What the maker does publish is a numeric body chart, so the age bands are anchored to real dimensions rather than left to guesswork.

The maker's height ladder for the ages these bands name:

• 2/3: 82–86 cm at 2, 93–98 cm at 3
• 4/5: 99–104 cm at 4, 105–110 cm at 5
• 6/7: 111–116 cm at 6, 117–122 cm at 7
• 8/10: 123–128 cm at 8, 129–134 cm at 9, 135–140 cm at 10
• 12/14: 141–152 cm at 12, 153–158 cm at 14
• 15/16: the chart lists 159–164 cm at 16; it does not list 15

Use your child's age band and, if they sit between bands, tell us their age and height when you join the list. Our fit guarantee stands behind the pick. That is what it is for when a maker publishes no hand chart.

Composition, as the maker publishes it: 45% recycled polyester, 55% polyester.
