A rug that looks right on the rail can be wrong for the horse standing in a wet, windy field at 6am. Shires Tempest rugs are a familiar choice for British horse owners because the range covers the jobs most yards face: keeping rain out, adding warmth when temperatures drop, and protecting horses through changing seasons without paying for features they will not use.
The best choice is not simply the warmest rug or the one with the highest denier figure. It is the rug that suits your horse’s clipping, turnout routine, shelter, coat condition and the weather actually expected at your yard. A hardy native in a sheltered paddock has very different needs from a fully clipped competition horse living out overnight.
What makes Shires Tempest rugs useful?
Tempest is Shires’ practical rug range, with options designed for turnout, stable use, fly protection and lighter seasonal coverage. That breadth matters when you need to build a sensible rug wardrobe rather than rely on one heavy turnout for every forecast.
Across the range, specifications vary by individual rug, but you will commonly see useful everyday features such as waterproof and breathable turnout fabrics, adjustable front fastenings, cross surcingles, tail protection and options with standard, detachable or fixed neck coverage. Always check the product specification for the exact model, as fill weight, outer fabric strength, lining and fastening design are not the same across every Tempest rug.
For many owners, the appeal is straightforward: recognised Shires quality, practical designs and a choice of weights that makes seasonal shopping less complicated. A lighter rug for wet autumn days, a mediumweight for colder weather and a warmer option for clipped horses can be more useful than owning several similar rugs.
Choose the right turnout weight first
Fill weight is a useful starting point, but it is not a complete answer. It tells you how much insulation sits between the horse and the outer fabric, usually measured in grams. It does not account for a horse’s natural coat, body condition, age, workload or whether it has access to a field shelter.
No-fill and lightweight rugs
A no-fill turnout, often called a rain sheet, is intended for wet and mild conditions where you need weather protection rather than extra warmth. It can also be useful for a horse that gets muddy, a clipped horse needing rain cover in warmer weather, or changeable spring and autumn days.
No-fill does not mean no purpose. A good waterproof outer can prevent a horse becoming soaked through in persistent rain, while the lack of insulation helps reduce the risk of overheating. For an unclipped horse with a thick coat, this is often the most-used turnout rug in the wardrobe.
Lightweight rugs, commonly around 50g to 100g of fill where available, bridge the gap when a rain sheet feels too little but a mediumweight feels premature. They are particularly handy for horses that are trace clipped, older horses that feel the cold, or exposed fields with plenty of wind.
Mediumweight and heavyweight rugs
Mediumweight turnout rugs are often the practical winter workhorse for clipped horses. They add meaningful warmth without automatically being the right answer for every cold day. A horse that is stabled overnight, fed well and wearing a medium clip may be comfortable in a mediumweight rug for much of a typical UK winter.
Heavier fills are best reserved for genuinely cold conditions and horses that need the extra insulation. A fully clipped horse living out, a poor doer, or a veteran may benefit, especially if turnout is exposed. However, a heavyweight rug on a horse that is warm, hairy or stabled for most of the day can lead to sweating, rubbing and discomfort.
Use your hand under the rug around the shoulder and behind the elbow, and assess your horse rather than relying only on the forecast. If the horse is damp or hot, reassess the rugging plan. If it feels cold through the skin, is tucked up or losing condition, it may need more protection, feed support or a discussion with your vet or nutritionist.
Neck style matters in British weather
A standard-neck turnout offers freedom around the neck and suits horses that do not need full coverage. It can be a sensible option for dry, cold days or horses with thick manes and good natural protection.
A combo neck gives continuous coverage from body to poll and is a popular choice for wet, windy turnout. It can help stop rain tracking down the neck and shoulders, especially on horses standing out in driving weather. The trade-off is that some horses are happier in a less restrictive design, particularly if they are broad through the neck or prone to rubbing.
Detachable neck covers offer flexibility. You can start the day with neck protection, then remove it when conditions improve. This is useful during unsettled autumn and spring weather, although it does mean keeping track of an extra piece of kit and checking attachment points regularly.
Whichever style you choose, check that the neckline sits smoothly. A neck that pulls tight when the horse lowers its head or gaps badly at the chest is not doing its job properly.
Getting the fit right
Even a well-made turnout rug will perform poorly if it does not fit. A rug that is too small can pull at the chest and shoulders, restrict movement and leave the quarters exposed. One that is too large may slip sideways, rub, or become caught behind the wither and shoulder.
Measure your horse according to the rug brand’s sizing guidance, normally from the centre of the chest around the widest part of the shoulder to the point of the tail. British rug sizes are generally shown in feet and inches, but do not assume your horse will take exactly the same size in every cut or brand.
When trying a rug on, the front fastening should sit comfortably without gaping or excessive tension. The shoulder should move freely when the horse walks, and the rug should sit level along the back without pulling backwards. Cross surcingles should be secure but not tight, while leg straps, if fitted, should be adjusted to avoid rubbing and tangling.
Check fit again after turnout. Some problems only show up once the horse has grazed, rolled and moved around the field. Look for ruffled hair at the shoulders, rubbed mane, pressure marks at the wither and a rug that has shifted to one side.
Outer fabric strength and real yard use
Denier is a measure often used to describe the strength of a rug’s outer fabric. A higher figure can be useful for horses that play hard, live with rug-pullers or regularly test fences and hedges. But it is not a guarantee that a rug cannot tear.
Fit, turnout companions and field conditions all affect how long a rug lasts. A lower-denier rug may be entirely suitable for a quiet horse on individual turnout, while a stronger outer is worth considering for a lively horse in a busy herd. It is often better value to buy the level of durability your horse needs than to pay for maximum strength that will make little difference to its routine.
Waterproofing also needs care. A turnout rug can lose performance if it is damaged, heavily soiled or washed with unsuitable detergent. If rain is coming through a sound-looking rug, check for worn areas, leaking seams and blocked breathability before assuming the original waterproof finish has failed.
Build a workable rug wardrobe
The most practical set-up is usually based on layers of use, not collecting every possible fill weight. For many horses, a no-fill turnout and one warmer turnout cover a large part of the year. Add a lightweight or mediumweight option when clipping, exposure or winter management calls for it.
Stable rugs have a different job. They provide warmth in a dry environment and are not a replacement for a waterproof turnout rug. Similarly, fly rugs protect against insects and sun but should be selected for fit and field safety rather than warmth.
If you are buying for a growing youngster or a new horse, avoid assuming you need a full collection immediately. Start with the rug most likely to be needed now, assess how the horse copes, and add another weight as the season changes. It keeps spending focused and avoids unused rugs filling the tack room.
Care that keeps rugs in service
Brush off dried mud before it becomes embedded, remove loose hair from linings and check straps and fastenings each time you change rugs. Small repairs are usually easier and cheaper before a tear spreads across the outer fabric.
Wash turnout rugs only when needed and follow the care label closely. Household detergent and fabric conditioner can affect waterproof finishes, while poor drying can leave a rug smelling musty. Professional rug cleaning and reproofing can be worthwhile for a quality turnout that is otherwise in good condition.
It also pays to label rugs clearly if you are on a busy yard. Similar navy turnouts are easily mixed up, and a rug returned in the wrong size or adjustment can cause fit issues the next time it is used.
Shires Tempest rugs give owners plenty of practical options, but the right one comes down to the horse in front of you. Choose the weather protection and warmth it needs today, check the fit carefully, and keep one eye on the forecast for tomorrow.
