Choosing rain gear that works

A rain suit has three failure points, and almost no listing on this shelf addresses more than one.

The three failure points

The fabric. Measured as a hydrostatic head in millimetres. Comparable, and only between products that publish it.

The seams. A row of needle holes through the cloth. Sealed — and fully rather than critically — or not. This is where most rain gear actually leaks, and it is the property least often published.

The zip. The largest deliberate opening in the garment. A flap, a waterproof strip, a sealing design: three separate measures, and naming them says the opening was thought about.

What this shelf actually publishes

One suit here publishes all three — a fabric figure, fully sealed seams and the zip described layer by layer. One publishes a fabric figure and a breathability figure and says nothing about its seams. One publishes laminated seams and no fabric figure at all. Two publish descriptions and no figures.

Read them against each other. Between the first three you can see what a complete specification looks like.

The figure everyone forgets

Breathability. Waterproofing alone describes a bag. A suit you work in has to let vapour out, and only one product in this family publishes both numbers.

The measurement nobody publishes

Leg zip length. A full-length zip goes on over boots at the roadside in the rain; a short ankle zip means taking your boots off on a hard shoulder. Not one listing here gives it.

The picks, and why they run in that order

The questions that come up first

What is a hydrostatic head?

A laboratory measure of how much water pressure a fabric resists, given in millimetres. It is comparable between products that publish it, and it describes the cloth between the seams — not the seams themselves.

Why do seams matter more than the fabric figure?

A seam is a row of needle holes driven through a waterproof fabric. Whether they are taped, and fully or only critically, decides whether water comes through. A fabric figure cannot answer it.

One-piece or two-piece?

A one-piece has no waist join, which is where water finds a two-piece; it is harder to put on at the roadside over boots. A two-piece deploys faster and has the join. They fail in different places.

What each price bracket buys

Deciding in one line

Useful comparisons

Head-to-heads already published between two models from this guide or this aisle.

How this guide is built

The models here come from the catalogue of this site. Specifications are those published by the manufacturer and on the Amazon product page; prices are what Keepa reported on the date below, and both move. The ranking uses declared specifications, the balance of stated strengths and limitations, and price. No product on this site has been physically tested, and nothing here claims otherwise.

Last checked on

Nothing written into the text below is a current price. Where an amount appears in a sentence, it is the reading taken on the day that sentence was written; what a shop is asking at this moment loads beside the product itself, and that is the figure to go by.

The tool we use ourselves

Kit chosen? Now make sure the price is real.

Helmets and riding gear are discounted over and over through the year — hardest of all in the weeks when nobody is riding, which is months away from when most of it is bought — and a struck-through figure on its own says nothing whatever about what the same model was charged at four weeks ago. UniverTrack holds a week-by-week history for every retailer, which means a reduction is judged against a price somebody actually paid rather than one dreamed up for the sale — and it tells you when the moment to buy has genuinely come.
