How to Choose the Right Turnout Rug
Set the spec from this horse’s situation, not the label.
You’ve decided to buy a turnout: how to pick the right spec, and how many you actually need.
The label numbers each answer one part of the job. None answers all of it.
Start from this horse’s situation, not the spec sheet.
This is the full guide: waterproofing, denier and fill, the neck question, fit and how many rugs you need. Short on time? Which Turnout Rug Does Your Horse Need? answers the one question first: whether this horse needs one at all.
A turnout rug has a harder job than any other rug a horse owns: waterproof, tough, warm to the right degree, and cut to stay put while the horse gallops, bucks and rolls. This guide takes the decision in the order that actually matters.
Start from this horse’s turnout
Before any product, four things set the spec: what the weather does where the horse lives out, whether there is shelter in the field, how rough the horse is in company, and whether it is clipped and has lost its own insulation.
A sheltered, unclipped, quiet horse in a mild climate needs a light, tough, genuinely waterproof turnout and little else.
A clipped horse in an exposed wet field needs more fill, a neck, and a spare.
Waterproofing is the number that matters
The single spec that separates a turnout from every other rug is hydrostatic head, the height of a column of water the fabric resists before it leaks. Roughly 1,500 mm is the floor for calling something waterproof, around 3,000 mm is what you want for reliable everyday turnout, 5,000 mm and up is for a genuinely wet climate. Taped or welded seams matter as much: an unsealed seam leaks however good the cloth is.
A showerproof sheet is not a turnout. Buy a real 3,000mm-plus rug, not a light shower sheet you are hoping will cope.

Where a number is documented we quote it. Where it is not, ask the retailer before you rely on it.
Denier is toughness, fill is warmth
These two numbers get run together and they answer completely different questions. Denier is the thickness of the outer fabric’s fibres, its tear resistance, not warmth. Fill weight is grams of insulation, and there is no industry standard behind the figure, treat it as a band.
Fine for a quiet horse in a safe field. Entry-level turnout weight.
Ripstop, for a horse that plays rough or fields with brambles and wire.
~1,500mm minimum, ~3,000mm everyday, 5,000mm+ for a wet climate.
0g waterproof only · ~100g light · ~200–250g medium · 300g+ heavy.
An MVP rating lets sweat escape. A warm rug that doesn’t breathe makes the horse damp from inside.
Rugging temperature table for the Mediterranean
Night temperature is the number to watch, and rain and wind move every row down by one. The bands are starting points for a healthy adult horse in normal condition with forage in front of it. An older, thin or fine-coated horse sits one row lower, a hardy native one row higher. Slip a hand under the rug behind the wither in the morning: comfortably warm is right, damp or hot means too much.
| Night temperature | Unclipped, dry & sheltered | Unclipped, wet & windy or no shelter | Clipped, dry & sheltered | Clipped, wet & windy |
|---|---|---|---|---|
| above 15 °C | nothing | nothing | nothing | 0 g rain sheet |
| 10 to 15 °C | nothing | 0 g rain sheet | 0 g sheet or 50 to 100 g | 100 g + neck |
| 5 to 10 °C | nothing, or 0 g if it rains all night | 0 g to 100 g | 100 to 150 g | 150 to 200 g + neck |
| 0 to 5 °C | 0 to 100 g | 100 to 200 g + neck | 200 to 250 g | 250 to 300 g + neck |
| below 0 °C | 100 to 200 g | 200 g + neck | 300 g | 300 to 400 g + neck |
On Mallorca most winter nights fall in the two marked bands, which is why a rain sheet and one medium rug cover most horses here. The bottom rows are northern-Europe territory or a clipped horse in a cold snap. Fill weights are manufacturer bands without an industry standard, so treat neighbouring cells as interchangeable and let the horse decide.

Turnouts come three ways, and the right one depends on how exposed the field is.
Standalone rug, cheapest and simplest. Fine for a horse with shelter.
Zips or clips on for flexibility. Buy the neck that matches the rug, they are not universal.
Covers the withers and crest fully, where wind-driven rain gets in first. Slightly higher rubbing risk.

A stable rug can be a little generous because the horse mostly stands still in it. A turnout has to move with a horse that gallops, spins and scrambles up, and stay in place doing it. Look for a real shoulder gusset, a pleat of fabric that lets the shoulder swing, that is the difference between a rug that rubs the shoulder bald by midwinter and one that does not.
There are two sizing systems, UK/US body length and EU withers-to-tail, and mixing them puts you a size out. Confirm which a rug is sold in before ordering.
- Shoulder gusset present. No seam pressing on the withers
- Reaches the tail-top with the head down, covers the belly
- Tail flap fitted
- Cross-surcingles, not one tight roller
- Leg straps adjustable, removable, looped through each other
- Correct sizing system confirmed
How many rugs you actually need
Be honest about your climate before you buy a wardrobe. A sheltered, unclipped horse in a mild Mediterranean winter genuinely gets through on one lightweight turnout, perhaps with a 0g waterproof for wet but mild days. A clipped horse in work needs at least a light and a medium, and then a spare in the weight it wears most, because a soaked rug needs a day or two to dry and re-proof.
Two moderate rugs give you far more usable range than one heavy one, and a spare of your everyday weight is worth more than a third weight you will reach for twice a year.

A good turnout is a multi-year purchase. A well-made 600–1200D rug with taped seams outlasts several cheap ones that delaminate and leak in a season. Used rugs can be a genuine bargain if you check them properly: seam tape intact, no flaking on the inside of the coating, all straps and clips present and working, then budget a wash and a re-proof before it goes on the horse.
Our turnout selection is filtered by hydrostatic head and seam construction first, then grouped by fill weight.
Two moderate turnouts and a spare will serve a horse better than one heavyweight bought “to be safe” and worn in the drizzle.
Set the spec from your situation first: weather, shelter, how rough the horse is, whether it is clipped.
Waterproofing is the key number: ~3,000mm hydrostatic head plus taped seams. Re-proofing is part of ownership.
Denier is toughness, fill weight is warmth. Separate decisions, and fill has no standard rating.
Neck: plain rug for a sheltered horse. Detachable or combo for exposed wet weather.
Turnout fit is about staying put in motion: shoulder gusset, correct depth, tail flap, cross-surcingles.
Most sheltered horses need one lightweight plus a 0g. Clipped working horses need a light, medium and spare.
Buy quality once. Check used rugs for seam tape and delamination. Budget an annual wash and re-proof.
General editorial guidance, not veterinary advice. Check any rug on the horse and monitor for rubs. Take decisions for a clipped or unwell horse with your vet.
