Lens Warmer Reccomendations

[DerekNZ]

Hi Team, anybody use lens warmers wraps for astro during cold winter shoots ?
Please share things or products you reccomend.
And also share the things you wouldnt reccomend (when not to use)

I am a Sony A7R4 shooter using 16-35gm fro astro.

Cheers

I bought a Camera Duck Standard All Weather Cover from B&H. It has slots for inserting hand warmer packets.
