Genuine wool military blankets are turning up in stables and yards right across the UK in 2026, mostly because owners are fed up paying full price for branded under-rugs that don't outlast a single winter. Surplus wool does the same job for less, if you know what you're buying.
- Wool military blankets for horse rugs need at least 90% wool content to hold warmth without felting fast.
- British Army Wool Grey Blanket is the safe stable buy for 2026 - genuine issue grey wool, check the grade.
- Greek/British Brown Wool Blankets suit turnout paddocks and travel padding better than showground stalls.
- Skip anything under 90% wool if you want proper surplus warmth rather than a synthetic-blend reproduction.
- A 200 x 140cm sheet at around 1.8kg is the rough benchmark weight for a decent wool stable blanket.
Why this matters
A horse standing in overnight in January doesn't need a blanket that traps damp against its coat, it needs one that pulls moisture away and still holds heat. Wool does that better than most synthetic fleece linings, which is exactly why army-issue blankets were made from it in the first place - they had to survive field conditions for years, not just a season in a tack room.
The British Army Wool Grey Blanket is a good example of what genuine issue wool actually looks like: heavier than a fleece cooler, dense weave, and built to be reused rather than replaced. That's the standard worth measuring everything else against.
Who this is for
This guide is for yard owners and DIY livery keepers running more than one horse who don't want to buy a branded turnout rug for every animal, plus grooms who need spare stable rugs and travel padding on hand without a big spend. It also suits anyone repurposing genuine militaria into working kit rather than leaving it in a wardrobe.
What to look for in wool military blankets for horse rugs
Wool content and weight
Check the percentage before anything else. Genuine surplus stock often runs close to 100% wool, while some reproduction blankets are made from a 75% wool blend with synthetic fibre mixed in for cost. The higher the wool content, the better it holds heat and resists matting under a surcingle or roller.
Size for the job
Most surplus wool blankets sit somewhere around 195-200cm in length, which works fine as an under-layer beneath a proper turnout rug or as a stable liner, but it won't wrap a 16.2hh horse the way a fitted rug does. Treat it as a liner or cooler, not a full replacement for a shaped rug.
Condition grading
Surplus stock is graded, and that grading matters more with wool than with cotton or nylon kit. New old stock (NOS) and Grade A pieces have had little to no use and no moth damage. Used or lower-grade blankets can still work for a stable liner but check for thin patches before you commit one to daily use.
Colour and visibility
Grey, brown and olive are the common shades in surplus wool stock. None of them are hi-vis, so if a horse is turned out near a road or bridleway at dawn or dusk, a wool blanket underneath a visible outer rug is the safer setup, not a standalone turnout layer.
Washability and care
Wool shrinks and felts if it's machine washed hot. Surplus blankets are almost always dry clean only or cold hand wash, air dry. Factor that into how often you can realistically rotate it, especially if it's doing daily stable duty rather than sitting as a spare.
Top picks for stable use
British Army Wool Grey Blanket - the safe pick. Genuine grey issue colouring, dense wool weave, and the benchmark most other surplus blankets get measured against on this list. Check the listed grade before buying since condition varies by batch. Buy for daily stable use in 2026.
Greek/British Brown Wool Blankets - the double-duty option. Brown wool hides mud and hay dust far better than grey, which makes it the better call for turnout paddocks and trailer padding rather than a showground stall where a cleaner look matters. Buy for paddock and travel use, Consider if you need something tidy for competition days.
British Army Blanket - the multi-use classic. Standard surplus wool blanket that moves easily between stable liner, dog bed base, and camp use if you're not committing every piece to horse duty. Less specific to any one job, but that flexibility is the point. Consider if you want one blanket doing several jobs around the yard.
What to avoid
- Low wool percentage sold as "military style" - a 75% wool blend reproduction, like the WW2 US GI style blanket above, is fine for a decorative throw but won't hold heat the way a genuine 100% wool piece does. Read the listing before assuming any khaki blanket is the real thing.
- Non-colourfast dye on grey or brown stock - older surplus can bleed dye when it gets wet, which is a problem against a grey or white coat. Test a damp corner before it goes anywhere near the horse.
- Moth-damaged militaria priced as collectible - some wool blankets are worth more intact as militaria than cut up for stable use. If a piece is genuinely rare, check how to identify genuine military surplus from replicas before you put it to work.

FAQ
Are wool military blankets safe to use as horse rugs?
Yes, genuine wool military blankets are safe as a stable liner or under-rug in 2026, provided the wool content is high and there's no moth or dye damage. They're not shaped like a fitted turnout rug, so use them as a liner rather than a standalone outdoor rug.
What's the best wool military blanket for stable use?
The British Army Wool Grey Blanket is the best all-round pick for daily stable use because it's genuine issue wool with a dense, warm weave. Check the listed condition grade before buying since surplus stock varies batch to batch.
How much do wool military blankets cost?
Surplus wool blankets typically run in the low tens of pounds, depending on origin, condition grade and size. Reproduction wool-blend blankets are usually priced similarly but carry less wool content.
Is 100% wool better than a wool blend for horse rugs?
Yes, 100% wool holds heat and wicks moisture better than a wool blend. A 75% wool reproduction blanket will still provide some warmth but won't perform as well as genuine surplus wool over a full winter.
Can you wash a wool military blanket?
Most surplus wool blankets are dry clean only or cold hand wash and air dry. Machine washing hot will shrink and felt the wool, so factor the care routine in if it's doing daily stable duty.
What size is a standard military wool blanket?
Most surplus wool blankets measure around 195-200cm in length, which works as a stable liner or cooler but won't wrap a large horse the way a fitted turnout rug does.
Do wool military blankets work as coolers after exercise?
Yes, wool's moisture-wicking properties make surplus blankets a solid choice as a cooler layer after work, pulling dampness away from the coat while the horse dries off in the stable.
One last thing
The detail most buyers miss is the grading, not the colour. A Grade A used blanket at half the price of a NOS piece often performs identically once it's on a horse rather than in a display case - the wool doesn't know it's second-hand.
