Overview
A padded, water-resistant calf jacket built to keep newborn and young dairy calves warm through the cold months. Designed for the critical first 4–6 weeks when calves burn body fat to stay warm rather than putting it into growth. Fits across the back and chest with four adjustable leg straps and a girth strap, leaving udder, legs and tail clear. One size adjusts to fit calves from approximately 40–100kg.
Key Features
- Water-resistant outer shell — sheds rain and shed-floor splash, dries quickly between uses
- Insulated padding — traps body heat to keep growth energy going into weight gain, not thermoregulation
- Four adjustable leg straps + girth strap — secure fit that doesn’t slip when the calf gets up, lies down or runs
- 120 x 80cm body — one size adjusts to fit calves roughly 40–100kg (approximately birth to 8 weeks for Holsteins)
- Reflective strip on the back panel — helps spot calves in dim sheds or at night during cold-weather checks
- Reinforced seams and bound edges — built to survive months of wear, repeated washing and rough housing in calf pens
- Lift handle on the back — grab point for putting it on, taking it off or moving the calf
Built for the cold-stress weeks
Calves are born with very little body fat and a high surface-area-to-mass ratio. Below their thermoneutral zone — roughly 15°C in the first three weeks — they start burning energy on staying warm instead of growing. A jacket extends the thermoneutral zone downward by 5–10°C, which means more of the milk they drink turns into liveweight rather than body heat. On a wet, windy night in a southern Australian or Kiwi winter, that’s the difference between a calf that thrives and one that scours and stalls.
The cut is purpose-designed for calves — not a downsized horse rug. The shoulders are shaped to give freedom of movement when the calf gets up off its brisket. Four leg-strap loops cross under the belly and through the rear legs, anchoring the jacket without rubbing. The girth strap sits behind the front legs where it stays put. Udder, tail and back legs are all left clear, so jackets can stay on heifer calves through to weaning if conditions stay cold.
The outer shell is a tough water-resistant polyester. It sheds rain, shrugs off muck, and survives a hose-down and a wash between calves. The padding holds its loft through repeated washes. The bound edges and reinforced strap anchors are the bits that fail first on cheap jackets — this construction has them stitched down properly.
Sized at 120cm long by 80cm wide flat, the jacket adjusts via the strap system to fit calves from around 40kg (a fresh Holstein or Jersey) up to about 100kg (an 8-week-old Friesian or 10-week Jersey). One jacket per calf for the cold-stress window, then wash and rotate to the next batch.

FAQ
When should I put a jacket on a calf?
Whenever ambient temperature drops below the calf’s thermoneutral zone — broadly under 15°C in the first three weeks of life, and under 10°C from three weeks onward. Wind and rain matter as much as raw temperature: a 12°C day with driving rain is harder on a calf than a still 5°C night. If the calf is shivering, hunched, or piling with pen-mates, it’s cold-stressed.
What size calf does this fit?
One adjustable size fits calves from roughly 40kg (newborn Holstein or Jersey) up to about 100kg (8-week Friesian, 10-week Jersey). For very small or premature calves, consider a smaller calf coat. Fit it snug enough that it doesn’t slip when the calf moves, but not so tight that it restricts the chest.
Is the jacket waterproof or just water-resistant?
Water-resistant. The outer shell sheds rain and splash and is fine for typical winter conditions in southern Australia and New Zealand. In sustained heavy rain or where calves are housed outside on dirt yards, expect some moisture penetration over hours — check calves daily and rotate jackets if they get sodden.
How do I clean it between calves?
Hose off heavy muck, then machine wash cool with a mild detergent. Skip fabric softener — it strips the water-resistant coating. Line dry, don’t tumble dry. Most jackets hold up to 20+ wash cycles before the padding starts to compress.
How long should a calf wear it?
Through the cold-stress period — usually birth to 4–6 weeks for autumn-born calves, longer if winter conditions persist. Pull the jacket once daytime temps consistently sit above 15°C and the calf has built body condition. Don’t leave it on once warm weather hits — calves overheat fast in a closed jacket on a sunny day.
