What to Pack for a Winter Trip (2026)

Layers

💡 Wear your heaviest coat and boots on the plane to free up bag space.

💡 Layering beats one thick item — you can add or remove as indoor heating varies.

Can I pack for a winter trip in a carry-on?

Yes — wear the bulkiest coat and boots, layer thin thermals, and OneBag's weight bar keeps you within the cabin limit.

What's the warmest way to pack light?

Thin merino/thermal base layers plus one good insulating mid-layer trap more heat per gram than bulky knits.
