An equine therapy blanket is the highest-value and highest-risk product in the animal light therapy category. It covers the largest area, consumes the most material, sits on the most valuable animal in the stable, and is the hardest format to keep positioned through a session. For an equestrian brand, it is also the product most likely to define how the range is perceived: a blanket that fits badly and shifts during use damages credibility faster than any listing copy can repair.
This guide covers the OEM decisions that determine whether a therapy blanket becomes a flagship product or an expensive lesson. HSY manufactures equine therapy formats alongside human panels and smaller animal devices from a 5,000+ square-meter facility with 6 automated SMT lines, which means the material and fastening questions below come from production experience rather than from a catalogue.
What Actually Separates a Therapy Blanket from a Rug
Equestrian buyers already own stable rugs, turnout rugs and cooler rugs. A therapy blanket has to justify a separate category, and the justification is engineering, not styling. Three features distinguish it.
- An emitter array distributed across the topline rather than concentrated in one zone, so the covered area receives comparable output instead of a hot centre and dead edges
- A fastening architecture that keeps the blanket in contact without restricting the shoulder, because a blanket that rides forward under a surcingle will bunch at the withers and lose coverage
- A control and power solution that a handler can operate while holding the horse, which in practice rules out interfaces that require two hands or a phone
If a supplier's blanket specification does not address those three points specifically, the product is a rug with LEDs sewn in. That distinction matters commercially because the buyer who pays a therapy-blanket price expects to feel the difference in fit and usability, not in the label.
Sizing and Fit: The Decision That Cannot Be Fixed Later
Blanket sizing is the single most consequential OEM decision, and the one most often deferred until after tooling. A pony, a cob and a full horse differ not just in length but in shoulder slope, wither height and barrel depth. A blanket patterned on one and scaled to the others will fit none of them well.
The practical approach is to define a primary size band for the target market, develop the pattern properly for that band, and treat additional sizes as separate pattern developments rather than as scaling operations. Brands selling into markets with a narrow breed mix can often launch with one or two sizes; brands targeting a broad equestrian audience should expect a size range of at least three.
Buyers should also decide early whether the blanket is designed to be used over a thin liner or directly on the coat. That single question changes the pattern allowance, the fastening tension and the thermal budget, and changing it after sampling means re-patterning.
Material Selection: Where Blankets Fail First
In field returns, therapy blankets rarely fail at the electronics first. They fail at the textile and the seams: a strap anchor tears out, a binding rolls and rubs, a lining delaminates after repeated sweat exposure, or a hook-and-loop panel loses grip. Material selection is therefore not a cosmetic decision.
- Outer shell: needs abrasion resistance against bedding and tack, plus dimensional stability so the pattern does not grow with use
- Lining: must tolerate sweat, and should not hold moisture against the skin in a way that keeps the contact area wet through the session
- Emitter carrier: the layer that holds the array needs enough stiffness to keep spacing uniform while remaining flexible enough to follow the topline
- Fastening hardware: webbing and buckles rated for equine load, not pet-grade equivalents; the cost difference is small and the failure consequence is not
- Seam construction: bound and reinforced at every anchor point, because stitch-only anchors are the first thing to fail under tension
A supplier should be able to state which material was chosen for each of those five roles and why. A quotation that lists a single fabric description is not a material specification.
Ingress Protection and Cleaning in a Real Stable
Stable conditions are demanding: dust, hay, bedding, sweat and wash water all reach the product in normal use. The blanket therefore needs a defined cleaning method that the electronics actually tolerate, agreed at design stage rather than discovered by the first customer.
Three levels are realistic. Surface wipe-down is the baseline and suits most designs. Spray-tolerant construction, with sealed connectors and a protected controller pocket, extends service life in clinic and rehabilitation use. Full washability requires a sealed electronics architecture and changes the enclosure design entirely, so it must be specified at the outset.
Buyers should ask for the cleaning method in writing, and should test it themselves on a sample before approving production. A blanket that cannot be cleaned after a sweaty session will not be used twice.
The Optical and Thermal Specification
A blanket covers a large body area, which changes both the optical and the thermal problem. Optically, the array must deliver comparable output across the covered zone; a centre-weighted design produces an uneven session that the end user notices as "the middle gets hot and the edges do nothing". Thermally, a large covered area traps heat against the animal far more than a leg wrap does.
Two records belong in the supplier's documentation: a model-specific irradiance measurement with the distance and method stated, and a session-length surface temperature log for the lining side. Without both, a buyer cannot compare two blankets meaningfully or assess whether the design is safe for a thirty-minute session. HSY's quality assurance process treats both as release criteria rather than marketing material, which is the standard we recommend buyers hold suppliers to.
MOQ, Tooling and Programme Sequencing
A therapy blanket carries more tooling and more material cost per unit than any other format in the category, so the programme sequence matters more. The sensible path is to develop one size band properly, validate it in the target channel, and only then extend the size range or add a second format.
Brands should also separate pattern development from tooling in the supplier's quotation, because the two carry different risk. Pattern development is iterative and can be refined; hard tooling for housings and connectors is committed spend. A supplier who can describe both separately is usually a supplier who has done this before.
MOQ and lead time depend on the size range, the textile selection and the packaging language, so they should be confirmed against the specific configuration rather than quoted generically. Brands planning multi-language retail packaging should raise it at briefing stage, because it affects both carton design and minimum quantities.
Frequently Asked Questions
How many sizes should a therapy blanket range include?
At least three for a broad equestrian market, covering pony, cob and full horse. Brands selling into a narrow breed mix can often launch with one or two. Each size is a separate pattern development, not a scaled version of the same design.
Can a therapy blanket be used while the horse is stabled overnight?
That is a design and supervision question rather than a product feature. The thermal budget, the timer behaviour and the fastening security all need to suit the intended use pattern, and buyers should confirm the intended session length and supervision arrangement with the supplier before specifying the product.
What warranty applies to equine therapy blankets?
Under HSY's current company policy, non-panel products including equine blankets carry a 1-year warranty, while rigid panels carry 3 years. The exact scope should be confirmed in the formal quotation because it depends on the design and the agreed test criteria.
What documentation should accompany a blanket order?
Model-specific irradiance records with stated measurement conditions, a session-length thermal log, the applicable compliance files with their scope stated, the agreed material specification, and the cleaning method the construction tolerates. Each document should be traceable to the exact configuration purchased.
Develop an Equine Therapy Blanket with HSY
Equestrian brands evaluating the format can request a development review covering size band, pattern approach, material specification and tooling scope before committing to production. Contact HSY to discuss an equine blanket OEM project with the target size range, channel and order volume.
