Black and white calf wearing a Cosy Calf jacket in an autumn pasture under a dark stormy sky

Tried, tested and produced by a farmer, for farmers

Keep every calf warm, growing, and out of the vet's bill.

Cosy Calf jackets cut feed, medication and bedding costs by putting energy into growth instead of warmth — and lower the risk of pneumonia and scours from chills and draughts.

Our story

Designed on a real farm, not a design studio.

After 15+ years rearing calves through Dorset winters, Mandy set out to solve one problem: how to keep calves at a steady body temperature without restricting airflow or increasing humidity — without an expensive, draught-free building to do it.

What our customers say

I liked the jackets a lot, during the cold weather they really helped keep the new-born calves warm which, in turn meant the calves were full of energy, not shivering in a corner. Also they grew better because the food was going to growth not creating body heat. PS. Please…

Brilliant product and the best I have seen on the market. They are durable, fit well, stay on and even wash well. We have to give the Cosy Calf Producer credit for our low pneumonia & scour cases and good growth rate because of the great start they give our…

Everyone who comes to the farm and sees the calves in jackets like them! The calves stay cleaner and do better in the jackets, and make a better price at market. Heifer replacements have fewer problems when wearing the jackets

A. Cotton

We were putting the coats on new born calves for the 1st 10 days to 2 weeks and we are very pleased with how the calves have responded, with less scours and increased growth rates

Our herd is out wintered. Your Cosy Calf jackets helped the young calves to survive in awful conditions.

Jersey Dairy Farm

Chard, Somerset

Fantastic, didn’t want to take them off! Well worth 1.) Money  2.) Persuading my husband of all the benefits these coats give to new-born’s up to weaning calf’s. We washed them in the washing machine, come up like new! Such good quality. Lovely, lovely, lovely. Fab!

Cosy Calf Jackets are a major factor in calf survival in extremes of weather.

I spend time taking rugs on and off horses. It makes so much sense to do the same to the most vulnerable animals on the farm – baby calves! They do so well with them, it helps them to get through the “day 10” scours – off milk, reducing need…
