A 300g turnout rug is a waterproof heavyweight rug for the coldest weather. Heavyweight rugs start at about 300g. They are mainly for clipped horses living out when nights drop below 0°C, and for unclipped horses only in very cold weather, below about -10°C. We stock them in standard and combo (full) neck styles.
Is 300g Right For My Horse?
- Cold but not freezing? A 200g turnout rug is often enough.
- Below freezing and clipped? 300g, with a neck cover.
- Need a little extra on the worst nights? Add a rug liner underneath.
When Is A 300g Rug The Right Weight?
Fill weight is grams of filling per square metre: more grams, more warmth (not more waterproofing). Our rug weight guide (based on BETA and British Horse Society advice) suggests 300 to 400g with a neck cover and a liner for a clipped horse living out below 0°C, and about 300g for a clipped, stabled horse at 0 to 5°C. Too much rug can make a horse sweat, so use the hand check: warm and dry under the rug is right.
Other Turnout Rug Weights
Go lighter with no fill turnout rugs, 50g turnout rugs or 100g turnout rugs, or see all medium weight turnout rugs, heavyweight turnout rugs and all turnout rugs. Ponies have their own page: pony rugs.
