How to wash a heavyweight hoodie so it lasts five years

You've got the one hoodie. The one you reach for every evening, wear at your desk all day, and pull on the second you get home. Six months in, it isn't quite the same — the fleece inside has gone flat and a little scratchy, the cuffs have lost their grip, and there's a faint bobbling across the front. Most people blame the hoodie. Usually it's the wash.

A good heavyweight hoodie is built to last years. What decides whether it actually does isn't the fabric, it's the few minutes of care around every wash. Get that right and a 450 GSM hoodie will outlive most of your wardrobe. Get it wrong and you can ruin a brilliant one in a single hot cycle. Here's how to keep yours soft, warm, and the right shape for the long run.

Wash it less often than you think

The single biggest thing you can do for a hoodie is wash it less. Every wash is a small act of wear — the drum pulls at the fibres, detergent strips them, heat shrinks them. A hoodie isn't a t-shirt sitting against your skin all day. Worn over a tee, it barely gets dirty.

Unless you've spilled something or properly worked up a sweat, a heavyweight hoodie can go five or six wears between washes without a problem. If it just needs freshening, hang it somewhere airy overnight — a hook by an open window does more than you'd expect. Spot-clean a single mark with a damp cloth rather than putting the whole thing through a cycle for one stain.

Cold water, gentle cycle, inside out

When it does need a wash, the settings matter more than the detergent. The aim is to clean the fabric without stressing it. Three rules cover almost everything:

• Turn it inside out. The brushed fleece interior is the part that keeps you warm, and it's the part that bobbles. Washing it inside out means the rubbing happens on the outer face, not against the fibres that matter.
• Wash cold. 30°C or below. Hot water is what shrinks cotton and breaks down the loft in fleece. A cold wash cleans everyday wear perfectly well and uses a fraction of the energy.
• Use a gentle cycle. Less spin, less agitation, less stretching. Where you can, wash it with similar weights rather than throwing it in with jeans and zips that snag.

Do up the drawstrings before you wash so they don't disappear into the hood, and fasten any zips so they don't catch on the fabric.

Fabric softener is the enemy of fleece

This is the one most people get wrong. Fabric softener feels like it should help — it's sold on softness. What it actually does is leave a waxy coating across the fibres. On brushed fleece that coating mats down the very loft that traps warm air, so the hoodie ends up feeling thinner and less warm over time. Skip it entirely.

Go easy on detergent too. More isn't cleaner. Excess detergent doesn't rinse out fully and builds up in the fleece, leaving it stiff and dull. A normal dose, or slightly less, is all a hoodie needs.

Never tumble dry a heavyweight

The dryer is where good hoodies go to die. High heat shrinks the body, tightens the cuffs, and bakes the fleece flat. A heavyweight holds a lot of water, so it takes a real beating tumbling around for an hour to get dry.

Air-dry instead. Lay it flat on a rack or a clean towel rather than hanging it — a wet heavyweight is heavy enough to stretch itself out of shape on a hanger, leaving you with droopy shoulders and a longer body than you started with. Reshape it gently while it's damp, keep it out of direct sun, and let it take its time. It'll dry into the same shape it went in.

Five years, not one

None of this is much effort. Wash it less, wash it cold and inside out, skip the softener, and never tumble dry it — that's the whole routine, and it's the difference between a hoodie that's still going strong in five years and one that's tired by Christmas. A piece like the Signature Heavyweight is made to be lived in for the long haul, and a few minutes of care is what lets it.
