The Thermic Battery C‑Pack 1700 B is a larger capacity sock battery delivering longer heat runtime for cold skiing conditions.

Why we like it:

We like how the extra capacity gives more peace of mind when you’ll be out all day in frigid temps.

Features and Functions:

1700 mAh capacity, USB charging, compatible with Thermic systems, compact and designed for in‑pocket carry with minimal bulk.

Fit and Sizing:

Ideal for serious cold‑weather sessions, resort days before lifts open or late‑night runs where feet get cold.

Bottom Line:

Slightly heavier and larger than smaller packs; if you usually only ski for a few hours you may not require the extra capacity.
