For most Australian horses through autumn and winter, a medium-weight rug at around 200g of fill is the right answer — warm enough for paddock nights in QLD, NSW and most of Vic without overheating during the warmer afternoons. Lighter 0–100g rugs are summer-only or for very mild coastal mornings. 300g and heavier “arctic” rugs only earn their keep in the alpine fringe, frosty mornings inland, and for clipped or older horses. The biggest mistake we see at Wholesale Horsewear House isn’t choosing too little rug — it’s choosing too much. Below: rug weights explained, climate-zone-by-zone, and which rugs from our range fit each one.
How “rug weight” is actually measured
Rug weight is fill grams per square metre — the amount of polyfill (or wool, in heritage rugs) sewn between the outer shell and the lining. It’s a measure of insulation, not the overall weight of the rug in your hands. A 100g fill rug feels light and breathable; a 300g fill rug is dense and traps a lot of body heat.
Manufacturers across the world use roughly the same bands:
- No fill / unlined — shell-only rugs. Cotton, canvas, ripstop or PVC mesh. Used for shade, fly protection, or as a stable cover over the top of a quilted layer.
- Light: 0–100g — a thin layer of insulation. Cool evenings, late-summer mornings, or for sensitive-skinned horses who run warm.
- Medium: 100–200g — the Australian workhorse rug. Suits most paddock horses through autumn and most of winter across QLD, NSW, SA and northern Vic.
- Heavy: 200–300g — frost mornings inland, alpine fringe, clipped horses, older horses, or horses that drop weight in winter.
- Arctic: 300g+ — Snowy Mountains, Stanthorpe-type frost belts, Tasmanian highlands, or for show horses kept clipped year-round.
Australian climate zones — what they mean for rug choice
Australia covers six Bureau of Meteorology climate zones (BoM publishes the map here), and the rug your horse needs in tropical FNQ is nothing like the rug your horse needs in Cooma or Stanthorpe. The four practical buckets we ship into:
Tropical north (Cairns, Townsville, Darwin): Year-round heat. The job a rug does here is shade, fly protection and rain coverage — not warmth. Unlined PVC shadecloth combos and mesh combos dominate. A real Wholesale Horsewear House customer in North Queensland summed it up on our Instagram earlier this year:
She’s not wrong. The unlined Aussie canvas pattern has earned its keep in the tropics for decades because it breathes faster than it warms — exactly what a North Queensland horse needs through the wet season.
Subtropical and warm temperate (SE QLD, coastal NSW, Perth, Adelaide): Mild winters, occasional cold snaps. A light to medium fill (100–200g) combo handles 95% of nights. You rarely need a heavy rug — but you do need one rug that can be layered up on the coldest mornings.
Cool temperate (Vic, Tas lowlands, inland NSW, Canberra): Real winter. Medium 200g is the everyday rug; heavy 300g comes out for frost mornings and for clipped horses.
Alpine and frost-belt (Snowy Mountains, Stanthorpe, Tas highlands, Vic high country): Sustained sub-zero overnight temperatures. 300g+ arctic-rated rugs, often with a neck rug or hood added separately.
The unrugged horse — when no rug at all is the right answer
This is the part most rug guides skip and most equestrian vets shout about.
A healthy, unclipped horse with normal body condition (BCS 5–6 on the 9-point scale) can comfortably manage down to about –5°C without any rug at all — as long as it has shelter from wind and rain and full access to forage. The thick winter coat a horse grows naturally is exceptional insulation, and rugging an unclipped horse on a mild morning forces it to dissipate heat through sweating, which then cools the coat and undoes the protection the horse grew itself.
The horses that actually need rugging in Australia are:
- Clipped horses — show, sport, racing
- Old horses (over ~20) and very young foals
- Thoroughbreds and lighter-coated breeds in cool-temperate zones
- Horses that drop weight in winter despite increased feed
- Sensitive-skinned horses prone to rain scald or mud fever
If your horse is none of those, the most important rug decision might be choosing not to put one on. The RSPCA Australia knowledgebase is blunt on this point — over-rugging is more common than under-rugging in this country.
Light (0–100g) — the summer and shoulder-season rugs
A light rug isn’t there to keep a horse warm — it’s there to keep rain off in a brief cold front, keep flies off in summer, or stop a clipped horse losing heat on a still cool morning.
The WHWH range that fits this category:
- Sunny Plus Rug and Sunny Plus Combo — light unlined fabric, designed for warm conditions, rain-resistant but breathable.
- Stradbroke Rug (Jute) and Stradbroke Combo (Jute) — the heritage Aussie jute weave. Unlined, breathable, naturally water-shedding. Stables and trainers have used the Stradbroke pattern for decades; we keep making it because it works.
- Highlander Unlined Combo — a true zero-fill shell. Wind and rain protection without insulation.
- Lecanto Fly Mesh Combo and Ripshield Mesh Combo — open-weave mesh for fly season; almost zero thermal effect.
If you’re in the tropics or you’re rugging an unclipped horse through a Toowoomba spring, this is your section. Browse the full summer horse rugs range to see what we currently have in stock in your horse’s size.
Medium (100–200g) — the Australian everyday rug
If you only own one rug, this is what it should be. Through autumn and most of winter for the bulk of Australian horse owners — South East QLD, the Hunter, the Riverina, Melbourne paddocks, Adelaide Hills — a 200g combo is the rug that actually lives on the horse.
This is also the weight band our GTL in-house rugs were designed around — the everyday Aussie paddock combo. Steve Smith of Steve Smith Cutting Horses sent this in last winter after his showteam ran a season on the GTL Winter Combos:
From the WHWH medium-weight range:
- Highlander Quilted Combo and Highlander Quilted Rug — our most-shipped winter combo. Medium fill, quilted lining, full neck cover.
- Simpson Lined Combo and Simpson Lined Rug — heavier 1200D ripstop shell, midweight lining. The combo most racing stables choose for paddock spelling.
- Breatha Combo — the medium combo that breathes well in our climate; popular for horses that get hot under heavier fills.
- Thermotex Combo and Thermotex Rug — therapeutic textile that’s a touch warmer than its fill grade suggests; popular for older horses.
- Sunshade Combo — mid-weight, summer-leaning combo for prolonged warm weather with cool nights.

Pick the band that matches your conditions, then pick the rug from that row.
Heavy and arctic (200g–400g+) — frost belt and clipped horses
You need a heavy rug if:
- Overnight temperatures regularly drop below 5°C through winter, OR
- Your horse is clipped, OR
- Your horse is over 20 and lighter conditioned, OR
- You’re in the Snowy Mountains, Stanthorpe, Glen Innes, the New England Tablelands, Tassie highlands, or any of the frost-belt towns where black-ice mornings are normal.
From the WHWH heavy and arctic range:
- Arctic Combo and Arctic Rug — the heaviest fill we stock, designed specifically for Australian frost-belt and alpine paddocks.
- Aussie Combo — heavy canvas combo, the traditional cold-weather work rug. Built to last seasons.
- Husky Combo — heavyweight combo with full neck cover.
- Perisher Combos and Perisher Turnout Combo — named for a reason. Heavy turnout for genuine cold weather.
- Alpine Woollen Combo — wool fill, available in our heritage red colourway. Stays warm even when damp, which synthetic fills don’t.
Add a Stradbroke Neck Rug, Horze Nevada Stable Neck Rug or Woodland Hood if your combo doesn’t already cover the full neck. The full winter horse rugs category lists current stock in every size we carry.
Sizing matters more than weight — and most people get it wrong
A perfectly-weighted rug in the wrong size will rub bare patches into a horse’s shoulder, slip backwards in the night, or trap moisture against the skin. We carry sizes from 3’0 to 7’0 across most of the range — far more sizing depth than our competitors — because a shetland and a 17hh warmblood both deserve a rug that actually fits.
Wholesale Horsewear House has been measuring up Australian horses since 2005, and the most common sizing mistakes we see are:
- Measuring along the side of the horse rather than from the centre of the chest, around the widest part of the shoulder, to the centre of the tail
- Buying for the horse’s current condition without allowing for winter weight loss or summer gain
- Sharing a rug between two horses of “about the same size” — there’s no such thing
- Not checking shoulder gusset depth — a deep gusset is the difference between a comfortable horse and a shoulder rub
Three questions, one rug
If you can answer all three, you can pick the right weight.
Question 1
What’s the overnight low?
Above 10°C → no rug or unlined. 5–10°C → light. 0–5°C → medium. Below 0°C → heavy.
Question 2
Is your horse clipped or older?
Yes → step up one weight band from the temperature answer. Clipped horses, horses over 20, and lighter-conditioned horses need more help.
Question 3
Wind and rain or just cold?
Wind + rain forecast → combo (neck coverage). Still cold night → rug only is fine. Sustained wet weather → waterproof outer matters more than fill grade.

Frequently asked questions
What weight rug should I put on my horse tonight?
For most of Australia, a medium 100–200g rug suits overnight temperatures down to about 0°C for an unclipped horse. Below that, step up to a 300g. If overnight is above 10°C and your horse isn’t clipped, you probably don’t need a rug at all.
Is 300g too heavy for a Queensland winter?
In SE QLD and the Darling Downs, yes — a 300g rug will overheat an unclipped horse on most winter nights. Stick with a 100–200g medium for everyday use and only switch to heavy on confirmed frost mornings.
Can I leave the same rug on day and night?
For a turned-out paddock horse in stable weather, yes. But check the rug at every feed for wet linings or pressure points. Day temperatures over 20°C with a 200g+ rug will overheat the horse — strip it during the day if the forecast is warm.
Do unlined canvas rugs keep a horse warm?
They block wind and rain, which is most of the comfort battle on a mild night. They have minimal insulation, so they’re not enough for cold or frosty nights on their own. Stack a quilted liner underneath for cold conditions, or step up to a lined combo.
What’s the difference between a rug and a combo?
A “combo” covers the neck as well as the body. A “rug” is body-only. Combos are warmer, stay in place better, and keep the mane dry — but they’re harder to put on, especially in a paddock. Most Australian buyers default to combos for winter and rugs for summer fly cover.
Why is my horse’s coat damp under the rug?
Either the rug isn’t breathable enough for the day’s temperature, or the horse is sweating because the rug is too heavy, or moisture is getting in through a worn shoulder seam. Step down a weight, check the seams, and consider a more breathable shell like the Breatha Combo.
How long should a quality horse rug last?
A well-fitted GTL or Highlander combo from us routinely lasts 4–6 winters on a paddock horse. Stable rugs last longer because they’re not exposed to weather.
Do you ship anywhere in Australia?
Yes — Australia-wide. Free postage on every order over $500. Phone or message us if you need help picking the right rug for your horse and we’ll talk you through it.

How to measure your horse for a rug
The exact method we use behind the counter at Toowoomba — centre-of-chest to centre-of-tail, why most owners measure wrong, and a sizing chart for our 3′0 to 7′0 range.
Rug vs combo — when do you actually need the neck cover?
The decision most owners get wrong on the first cold morning. When a combo earns its keep, when a body-only rug is plenty.
Sunshade vs fly mesh combo — which one for the Aussie summer?
The summer rug split that catches everyone — what each one actually blocks, and the GTL Shadecloth combo’s 75% UV story.
Synthetic vs canvas (jute) horse rugs — which lasts longer?
The Stradbroke Jute story, where modern synthetics win, and why we still ship both.
How to wash and care for your horse rugs
The wash, the seam check, the seasonal rotation. Get this right and a quality combo lasts you 4–6 winters.
