The Piece of Rain Kit Almost Nobody Owns — and Should
Most people who walk regularly in Ireland have a waterproof jacket. Almost nobody has waterproof trousers. And then they come home from a walk with a dry torso and completely soaked legs, wondering why the jacket didn’t help. Wet legs are exactly as miserable as a wet torso, and they’re just as effective at making you decide not to bother tomorrow. A waterproof jacket without matching trousers is half a solution to an Irish weather problem.
The Portwest rain trousers solve this without fuss. They pull on over whatever you’re already wearing — normal trousers, leggings, tracksuit bottoms — with an adjustable elastic waist that fits most people without adjustment. They’re unisex, which means one pair works for any member of the household and pairs with any waterproof jacket you already own. They pack down small enough to live in a bag alongside your jacket. And because they’re a standalone purchase rather than part of a suit, they work as the missing piece of an existing setup or as the starting point for building one.
At €12.16 and with the #1 Best Seller badge backed by over 8,000 reviews at 4.4 stars, this is one of the easiest decisions on this list. There is no reason to come home from a walk with wet legs when the solution costs less than a takeaway coffee for two. If you already have a waterproof jacket, this is the item that makes it work.
How to Use Your Portwest Rain Trousers
Pulling them on over your shoes. The leg openings have a wide elastic that is designed to accommodate most footwear. Stand upright, hold the waistband, and step in one leg at a time — the opening stretches enough to fit over a standard walking shoe or trainer without having to remove it. No sitting on a bench, no hopping about on one foot on a wet pavement. For most people this takes about twenty seconds per leg and becomes second nature within a few wears.
Wearing over normal trousers or leggings. These trousers are over-trousers, not a replacement for what you’re wearing underneath. Pull them on over your everyday clothes — regular jeans, walking trousers, leggings, or tracksuit bottoms all work. The adjustable waist means they sit securely regardless of the waistband of what’s underneath. In cold weather, the layer underneath provides warmth while the Portwest trousers block the rain and wind.
Adjusting the waist for a secure fit. The waistband is elasticated and typically adjustable with a drawcord or button tabs depending on the version. Take a moment to adjust before you start walking — a correctly fitted waist stops the trousers from sliding down during movement, particularly on hills or if you’re walking at a brisk pace. The adjustment takes a few seconds and stays put for the walk.
Keeping them in your bag. These trousers pack down small — fold them lengthwise, then roll loosely from the ankle up, and they compress to roughly the size of a folded newspaper. Keep them in your everyday bag alongside your waterproof jacket. The discipline is the same as with a packable jacket: they’re most useful when they’re already with you, not when you’ve left them at home on a morning that started dry.
Washing and care. Machine wash on a cold cycle — these trousers use a PVC coating for waterproofing rather than a DWR fabric treatment, which means care is simpler. No tumble drying needed or recommended; line dry or hang dry instead. No fabric softener. Because the waterproofing is the PVC coating itself rather than a surface treatment, it doesn’t degrade the same way as DWR on fabric waterproofs, and there is no retreatment needed to maintain performance.

Frequently Asked Questions
Yes — that is exactly how they are designed to be used. The adjustable elastic waistband fits over regular trousers, jeans, leggings, or tracksuit bottoms without being tight or uncomfortable. You don’t need to change your clothes before a walk; just pull the Portwest trousers on over whatever you’re wearing and you’re waterproof below the waist.
The PVC coating blocks rain completely and provides meaningful wind resistance, though these trousers are not certified windproof in the same way as performance hiking gear. For walking pace in exposed conditions, they perform well and eliminate the cold feeling of wet trousers entirely. If wind resistance is your primary concern on coastal or hillside routes, pairing them with a windproof jacket gives you solid combined protection.
Yes. A jacket protects your torso; without trousers your legs get just as wet, which is equally miserable and just as likely to make you cut the walk short. Most people own a waterproof jacket but skip the trousers — and this is exactly why a wet walk is still a wet walk despite having good kit on top. At €12.16, these trousers complete the setup for almost nothing.
In most cases, yes. The leg openings have a wide elastic that accommodates most walking shoes, trainers, and light boots. You can pull the trousers on without removing your footwear and without sitting down — just step in and pull up. For very bulky or tall boots, check the opening width against your footwear before ordering, but for standard walking shoes they fit without issue.
Machine wash on a cold cycle. The PVC coating does not require the same DWR care as fabric waterproofs — avoid tumble drying and instead line dry or hang dry. No fabric softener needed. They dry quickly and don’t need any retreatment to maintain their waterproofing; the PVC coating is the waterproofing itself, rather than a surface treatment that degrades over time.
