Winter Field Kit

What changes when the forecast low goes below freezing — and what quietly stops working if you do not change it.

Winter is not the three-season kit plus a warmer coat. Two things on the standard list actively fail in the cold: hollow-fibre water filters are destroyed by freezing, and lithium headlamp cells lose most of their capacity below −10 °C.

Ground conduction, not air temperature, is what ends a cold night. The pad matters more than the bag, and it is the item people under-buy most often.

Cold-weather sessions carry additional gear requirements and pre-session screening. Check the session addendum — it is the controlling document, not this page.

What fails in the cold

Swap or supplement these before a winter session. This is the section that actually matters.

Layers

No cotton next to skin, per L1-CLO-01. This is not a preference.

Tools and cordage

Cold makes everything take longer. A saw beats an axe when you are tired.

Fire and first aid

This is a shopping list, not a requirement

NBWSR does not require any particular brand, and nothing on this page is a condition of certification. The controlling document is the session-specific gear addendum sent to registered students 14 days before start — if it disagrees with this page, follow the addendum.

Bring what you already own if it meets the clause. Instructors check kit on day one and would rather see honest gear than new gear.
