The cold-weather reference
Tested advice on parkas, insulation, layering and winter gear — searchable, precise and free of fluff.
Layering
How people work through Alaska's extreme cold — the North Slope's arctic-rated loadout, bunny boots, the -80 °F record, and the layering system that keeps oil crews and scientists alive at -60 °F.
Buying Guides
Why "comfort rated to -20 °C" means almost nothing, the specs that actually predict warmth, and a checklist for judging any winter jacket from its listing.
Care & Repair
Why compression kills down, the wash-before-storage rule, and a room-by-room guide to putting away parkas, boots, wool and shells so they work next November.
Footwear
How winter socks actually keep feet warm, why doubling up backfires, merino vs. synthetic blends, and matching sock weight to boots and activity.
Accessories
Why mittens are warmer, when gloves still win, the liner system that beats both, and how to fix chronically cold hands at the wrists instead of the fingers.
Care & Repair
Why your "waterproof" jacket suddenly soaks through, how to tell DWR failure from membrane failure, and the wash-in vs. spray-on restoration process step by step.
Buying Guides
What softshell and hardshell actually mean, where each one wins, and a plain decision table so you stop buying the wrong jacket for your weather.
Insulation
Fill power decoded, the wet-weather truth about down, and a decision table for choosing between down and synthetic for your climate and budget.
Buying Guides
Fill weight over fill power, why temperature ratings are marketing, shell fabrics, fit rules and the features worth paying for in a serious parka.
Layering
Base, mid, shell — how the classic layering system actually works, what each layer is for, and the four mistakes that make people cold in expensive gear.
Care & Repair
The safe machine method — down soap, gentle cycle, dryer balls, full drying — plus DWR re-proofing and the mistakes that permanently kill loft.
Buying Guides
Hydrostatic head, breathability numbers, 2L vs 3L construction and DWR — how to read a shell jacket's spec sheet like someone who tests them.
Layering
The layer that touches your skin decides whether you're warm. Merino and synthetic compared honestly — weights, blends, and why cotton is a safety issue.
Footwear
What 200 g vs 400 g insulation means, why fit beats fill, outsole compounds that grip ice, and the sock system that makes any boot warmer.
Layering
A head-to-toe checklist for extreme cold — core layering, the extremities that actually hurt, moisture discipline and the warning signs to respect.
Every recommendation on this site has been worn, washed and winter-tested. If a spec is quoted, it means something in the field.
Fill power and fill weight, grams of insulation, millimetres of hydrostatic head — decoded so a tag reads like information, not marketing.
