12 min read Last updated: January 2026 Struggling to keep a 17.5" jump saddle stable and rub-free on a long-backed horse? This guide shows exactly which XL, high-wither, contoured pads work for UK conditionswhy staying under 10 mm and extending 510 cm past the panels delivers even pressure, cooler backs, and confident, balanced jumps. Quick Summary Short on time? Here are the key takeaways. Area: Size & Cut What To Do: Choose an XL, jump-cut, high-wither, contoured pad that extends 510 cm past the rear of your 17.5" saddle panels and keeps a clear spine channel. Why It Matters: Prevents loin rubs and keeps the saddle balanced on long backs. Common Mistake: Using a standard-length pad that exposes panel edges or pinches the spine. Area: Keep It Thin What To Do: Select a low-profile pad 10 mm (e.g., 8 mm VIP) and avoid stacking pads. Why It Matters: Extra thickness alters saddle balance and creates pressure points. Common Mistake: Over-padding to fix fit issues, which tips a correctly fitted 17.5" saddle. Area: Shock Tech What To Do: Use proven shock absorption without bulk: VEteq polymer, AirTech layers, twin-sided gel, or ThinLine open-cell for jumping. Why It Matters: Lowers peak impact while preserving close contact and stability. Common Mistake: Choosing thick foam that deadens feel and upsets saddle fit. Area: Breathable Lining What To Do: Pick bamboo or Merino-lined jump pads to wick sweat fast and minimise friction in UK conditions. Why It Matters: Keeps long backs cool, dry, and comfortable on longer sessions. Common Mistake: Riding in non-wicking fabrics that stay wet and rub. Area: Measure & Fit What To Do: Measure wither to last rib, then fit for 23 cm spine/wither clearance and 510 cm pad overhang past panels; test walktrotcanterjump. Why It Matters: Confirms even pressure and stable performance under a 17.5" jump saddle. Common Mistake: Judging fit unmounted and skipping a ridden check. Area: Anti-slip & Girth What To Do: Add Tech Grip/XGrip surfaces if needed and ensure straight, even girthing with a smooth girth sleeve. Why It Matters: Improves stability on take-off and landing, preventing pad creep. Common Mistake: Ignoring crooked billets or harsh girths and blaming the pad for movement. Area: Seasonal Choices What To Do: Summer: mesh/bamboo thin pads; AutumnSpring: bamboo/Merino with AirTech/gel; Winter: XL low-profile shock tech. Why It Matters: Matching materials to weather keeps the back dry and cushioned year-round. Common Mistake: Using one heavy pad all year, causing heat build-up or waterlogging. Area: Care & Replace What To Do: Brush debris, machine-wash every 35 rides, air-dry flat, rotate pads, and replace when compressed, frayed, or slipping persists. Why It Matters: Clean, resilient pads protect skin and maintain shock performance. Common Mistake: Tumble-drying or riding on flattened pads that no longer rebound.

Care and longevity: washing, drying, and when to replace Quick-buy checklist and JHR recommendations Long-backed horses can be a joy to jump, but they ask more of your saddle pad: more coverage, more stability, and smarter shock absorption. If you run a 17.5" jump saddle, an XL, high-wither, thin-profile pad is the difference between even pressure and loin rubs.Key takeaway: For a long-backed horse under a 17.5" jump saddle, choose an XL, high-wither, contoured pad that extends 510 cm beyond the panels, is under 10 mm thick, and uses breathable, shock-absorbing tech (gel, viscoelastic polymer, or open-cell) for UK conditions.What makes a pad right for long backs and 17.5" jump saddles?The right pad is longer and wider (XL), high-wither cut, thin (ideally under 10 mm), and contoured to clear the spine while extending 510 cm past the saddle panels. That keeps the saddle balanced, prevents loin rubbing, and maintains feel over fences.XL designs such as the VIP Saddlepad XL Wide are purpose-built for this job: theyre designed longer and wider for horses with more back length and are only 8 mm thick so they dont alter saddle fit while still offering serious shock absorption. The VIP uses VEteq viscoelastic polymer that moulds like a second skin and disperses heat and impact, with raised bobbles to increase surface area and relieve pressure points.

These solutions aim to spread weight and impact without bulk that could upset saddle balance. Sources: Premier Equine, KM Elite ThinLine.Consider your horses discipline, size, and sensitivity. Pads like AirTech Shockproof are ideal for high-impact work [e.g., jumping in 17.5" saddles], while Merino Wool provides natural moisture control and soft cushioning for long-backed horses. Premier Equine International (source)How to measure and size an XL pad correctlyMeasure from the top of the wither to the last rib, then select an XL pad that sits 510 cm beyond the rear of your 17.5" jump saddles panels and clears the spine by 23 cm. This follows general British Equestrian fit guidance for pressure-free saddle areas.Heres a quick step-by-step for long-backed horses:Back length: With the horse standing square, measure wither tip to last rib; note the shape of the topline and wither height.Pad length: Choose XL/longer pad variants to extend 510 cm beyond the rear of the saddle panels for full protection without overhang into the loins.Spine and wither clearance: Pick high-wither, contoured spines that give 23 cm of clearance when girthed no contact along the dorsal midline.Thickness: Keep pad thickness under 10 mm to avoid altering the balance of a properly fitted 17.5" saddle (the VIP XL is 8 mm). Source: Comfy Horse Company.Trial fit: Place the pad on your horse without the saddle first; check it moulds smoothly over the wither and back curve with no bridging or bunching.Quick tip: Opt for contoured spines (e.g., VIP XL Wide, LeMieux high-wither jump cuts) to avoid wither pinch on TB types and to keep airflow along the spine on broader natives. Sources: Comfy Horse Company, LeMieux.The best materials for UK jumping and long backsFor UK jumping, combine a breathable lining (bamboo or Merino) with proven shock absorption (viscoelastic polymer, perforated shock layers, gel, or open-cell) in a low-profile build. This keeps sweat moving, pressure even, and saddle balance true.Three material choices stand out for long-backed horses:Breathable linings for moisture control: LeMieuxs 100% bamboo lining excels at wicking and minimising friction on sensitive skin, while Merino wool options from brands like Premier Equine help manage sweat during longer jump sessions.

If it alters balance, its the wrong thickness or cut.Use this quick, repeatable fit process:Place the pad high on the wither, then slide back to seat it along the hair, maintaining a clean channel over the spine.Set the 17.5" jump saddle; check high-wither contouring prevents pinch and that the pad extends 510 cm behind the rear panels, not into the loins.Girth up and lift the pad into the gullet for 23 cm clearance from wither to mid-back; ensure no pad material is touching the dorsal spinous processes.Walktrotcanterjump a cross pole; assess for slippage or bunching. Anti-slip features (e.g., Premier Tech Grip Pro or LeMieux X-Grip) can lock everything in place for take-off and landing. Source: Premier Equine, LeMieux.Post-ride, check sweat patterns you want even dampness without dry hot spots that signal bridging or peak pressure.Pro tip: Pair anti-slip pads with a smooth, well-fitted girth sleeve and check symmetry of your girth billets; stability starts at the saddle, not just the pad.Common mistakes to avoid:Using a standard-length pad on a long back this invites loin rubs and exposed panel edges. Upgrade to XL/high-wither designs such as LeMieux jump cuts or VIP XL Wide.

Sources: Premier Equine, GS Equestrian.Winter (hunting or chilly schooling):Stick with XL, contoured shock absorption (VEteq/gel) to keep muscles warm and comfortable over longer minutes in the cold.Between outings, protect toplines and maintain condition with appropriate winter turnout rugs to keep backs dry and ready for the next schooling day.Competition prep: If your calendar includes British Eventing or Riding Club shows, line up breathable jump pads early, along with crisp womens competition clothing that meets venue standards and keeps you cool during long classes.Care and longevity: washing, drying, and when to replaceWash machine-compatible pads every 35 uses, air-dry flat, and replace when compression, frayed bindings, or persistent slippage appear. Clean pads last longer and keep friction low on sensitive long backs.Routine that works in UK conditions:After wet or muddy sessions, brush off hair/grit, then machine-wash compatible pads on a gentle cycle; some modern pads (e.g., Winderen anatomic styles with embossed cotton) are designed for easy washing. Source: Winderen guidance referenced in practical recommendations.Avoid tumble drying; air-dry to preserve shape, especially on high-wither, contoured pads.Rotate two or more pads to allow full drying between rides, particularly in damp months.Check stitching and binding monthly long backs magnify movement, so small faults turn into rubs quickly.Groom before tacking up; a clean coat reduces friction under the pad. Stock up on quality grooming tools to keep the back and withers debris-free.When to replace: If your pad has flattened areas that no longer rebound, visible bobble wear (on polymer/gel styles), or it repeatedly slips despite correct girthing, its time for a new one. Remember, thickness creep over time can alter your 17.5" saddles balance stay under that 10 mm guideline for jumping.Quick-buy checklist and JHR recommendationsChoose an XL, high-wither jump pad under 10 mm thick, with breathable lining and proven shock absorption, that extends 510 cm past the panels and stays stable at speed.
