No - cold hands lose dexterity and grip strength measurably, which causes accidents.

A dropped tool or a mishandled load is a direct consequence of reduced grip.

Cold hands are also more vulnerable to injury and slower to heal.

So keeping hands warm prevents accidents independently of the impact pads.

Prolonged cold exposure has its own health consequences.

Treating warmth as a productivity or comfort question understates what it does.

No, and conflating them is the common mistake - a glove can be warm and let water in.

Once wet, insulation stops working almost entirely.

In wet cold, which is most cold outdoor work, a waterproof membrane matters as much as the insulation.

Gloves that are merely insulated fail quickly in those conditions.

Breathability matters too, since sweat trapped inside wets the insulation from within.

Specifications should state both properties rather than one.

Enough that some tasks cannot be done, and workers remove the gloves regardless of temperature.

That removal is when both the cold injury and the impact injury occur.

Designs preserving fingertip feel are worth more than designs maximising thermal rating.

Pre-curved fingers and articulated construction help considerably.

Trialling with the actual work is the only reliable way to judge it.

The warmest glove available is often not the glove that gets worn.

Thermoplastic materials stiffen as temperature falls, which can reduce energy absorption.

A pad tested at room temperature may not perform the same at -20.

Manufacturers specifying a glove for cold conditions should state performance at the relevant temperature.

That information is not always published, and it is worth asking.

Pads that have become brittle can crack under impact rather than absorbing.

It is a genuine technical consideration rather than a theoretical one.

Often yes - the liner stays on when the outer comes off for a task.

That keeps some protection on the hand during exactly the moment it would otherwise be bare.

It also allows the insulation level to be adjusted through the day.

Thin liners add warmth with little loss of dexterity.

The outer glove must be sized to accommodate the liner, or circulation is restricted and hands get colder.

Restricting circulation with a tight glove defeats the whole purpose.
