Before You Shoulder the Pack

The questions we hear most often, answered plainly. Where the honest answer is "it depends", we say what it depends on.

01 / power

Batteries and Light

Why does my phone die in the cold even when the battery shows charge?

Cold increases a lithium-ion battery's internal resistance, so voltage drops under load and the phone shuts down to protect itself. Warming it in an inner pocket usually restores much of the charge.

Can I charge a power bank outside in sub-zero temperatures?

Most manufacturers advise against charging lithium-ion batteries below about 0 °C because it can cause permanent damage. Warm the bank and device first. See why batteries sag.

Which batteries are best for a backup headlamp in winter?

Lithium primary AA or AAA cells generally perform well in deep cold and have long shelf life, provided the headlamp supports them.

02 / warmth

Staying Warm

Are heated gloves worth it?

They are most useful for stop-start activities such as photography or ice fishing. Runtime on high settings is limited and shorter in cold, so they complement rather than replace a good glove system.

Down or synthetic insulation for Nordic winters?

Down is lighter and warmer in dry cold; synthetic keeps more warmth when damp, which suits wet coastal conditions near 0 °C. Compare them in our insulation table.

Do I need crampons or traction aids in Nordic cities?

Pavements can be icy for weeks. Simple slip-on traction aids or shoes with winter soles are widely used by residents. Full crampons are for mountain terrain.

03 / protection and care

Keeping Dry and Maintaining Kit

What does IPX7 mean?

Under IEC 60529, IPX7 indicates protection against temporary immersion, typically tested at up to 1 metre for 30 minutes.

Is a rain cover enough to keep my pack dry?

Rarely on its own. A waterproof liner or dry bags inside the pack are more reliable, especially in wind.

How should I dry wet boots?

Remove insoles, loosen laces, stuff with newspaper and dry at room temperature with airflow, away from direct heat. More in our care sheets.
