Weather class W1 – W4
Every cover here lists its water column in millimetres, whether the seams are taped, and what the sun does to it over time. Four classes, forty-three items, and no adjective standing in for a number.
One panel, two conditions
The same panel in dry sun. These are the figures the fabric was tested to before it went outside.
The main entrance to this shop
We do not sort covers by what they go over. We sort them by how much weather has to stop at the fabric, because that is the thing that decides whether a cover works for you.
Keeps dust, pollen and overnight condensation off something that is already under a roof. It is not a rain cover and we do not sell it as one.
Sheds rain over a summer season outdoors. Seams on most W2 items are stitched and not taped, which means the seam is the first place water gets through.
Built to stay outdoors through a full year including winter. Taped seams and vents on most items in this class, because a cover that stays on for months has to let condensation out.
The heaviest fabric we carry, for salt air, high sun hours and long periods where nobody takes the cover off. Taped or welded seams, reinforced corners, vents.
These classes describe what the fabric was tested to. They are not a promise about your weather.
What is on every product page
Anyone can print a water column figure. The useful part is what sits next to it: whether the seam is sealed, whether the air can get out, and whether anyone actually measured the UV.
Seam treatment
Every needle hole is an opening. Under sustained rain, water finds the seam before it finds the fabric. So we print the seam treatment next to the water column on every page, and where it is stitched and not taped, we say so in those words.
Vents and condensation
A sealed cover left on for months collects condensation and does more damage than the rain it kept out. Vents are marked on every item, and the ones without them carry the note explaining what that costs you.
UV and fading
Where a fabric has been through a xenon exposure test, we print the hours and the blue wool grade. Where it has not, the page says not tested rather than leaving the field empty. Only two items here carry a UPF number, because only two have a report behind them.
Four hours, one panel
Beading on the surface tells you the coating is intact. It tells you nothing about the seam, and nothing about the air trapped underneath. Both of those are on every product page here.

Before you order
Measure before you order. A cover that is too tight tears at the corners, and one that is too loose flogs in the wind and wears itself out.
Four questions
The class finder recommends downwards when your conditions do not need the heavier fabric, and it tells you plainly when what you were about to buy will not last where you are putting it.

What we will not tell you
That depends on your sun, your salt and how often you wash it. Anyone who gives you a number for that is guessing on your behalf.
It depends far more on how you fastened it and what it is stretched over than on the cloth. We tell you how to fasten it instead.
Thirty-nine of the forty-three items here have never been UV tested, and their pages say so. Two carry a UPF figure because two have a test behind them.
It does not. A cover is a cover: it does not hold a boat in place, and a roll-top bag is not a flotation aid. Those are separate things, and you buy them somewhere else.
