What does allweather mean?
"Allweather" (more commonly written "all-weather") is an adjective describing things built to perform reliably in every kind of weather — rain, snow, heat, or cold. It attaches most often to practical goods and facilities: allweather tyres that grip on wet and dry roads alike, allweather coats, tents, paints, and the allweather pitches that let sports continue through the seasons. By extension it carries a figurative sense, applied to people and relationships: an allweather friend is one who remains steadfast in hard times, standing in deliberate contrast to the fair-weather friend who disappears when conditions worsen. The word's connotations are thoroughly positive — durability, dependability, and freedom from seasonal limitation — which explains its popularity in advertising and product descriptions. For readers, it is a compact way of signalling that something, or someone, will not let them down when the weather does its worst.
