Kids' PE Kit: What Schools Need in 2026
Around 40% of UK primary school parents buy at least one PE kit item twice in the same school year, usually because they bought the wrong fabric or the wrong size. Get it right once.
What Every List Actually Requires
UK school PE kit lists look intimidating, but they almost always come down to the same four items. A plain short-sleeved t-shirt, shorts, socks, and trainers. The colour varies by school, so check the letter before you buy.
White is still the most common t-shirt colour in primary schools. If you pick up a 3-pack of plain white children's t-shirts, such as the Fruit of the Loom Kids Valueweight T-Shirt, you will cover most schools and have spares for the week. Look for 100% cotton if your child overheats, or a cotton-polyester blend if you want faster drying between washes.
Shorts should sit just above the knee. Too long and they restrict movement during gymnastics. Too short and children complain they are cold on outdoor days. Navy is the safest colour choice where the school does not specify.
Sizing: Buy Ahead or Buy to Fit
PE kit takes a harder beating than school uniform. Children stretch, roll, sprint, and sit on gym floors in it. Buy to fit now, not to grow into. A t-shirt that is two sizes too big catches on equipment and creates a safety risk in gymnastics and climbing lessons.
Check the chest measurement rather than the age label. A child wearing aged-7 school shirts might comfortably fit aged-8 PE shorts simply because shorts have more give. If you are unsure, size up by one, not two.
Fabric: What Survives the Term
Polyester blends, specifically anything labelled quick-dry or moisture-wicking, come out of the wash looking cleaner after muddy outdoor sessions. Pure cotton greys out faster and holds mud in the weave. For summer terms, breathable mesh-panel shorts from brands like Puma or Under Armour Kids hold their shape longer than supermarket own-brand alternatives.
A good option for year-round use is the Amazon Essentials Boys' Active Performance T-Shirt, which uses a 100% polyester weave and holds its white colour well across a full term of weekly washes.
The Bag and the Label
A drawstring PE bag keeps muddy kit separate from school books. Buy a plain one in a bright colour so your child can spot it quickly in the cloakroom. Write the name in permanent marker on the inside label on day one. Unlabelled PE kit disappears from lost property within a fortnight.
The Bagbase Junior Drawstring Bag comes in 12 colours and fits a full kit change with room for trainers. It weighs almost nothing and takes machine washing at 30 degrees.
Making It Last All Year
Wash PE kit at 40 degrees on a quick cycle, not 60. High heat is what shrinks polyester shorts and turns white t-shirts yellow. Tumble dry on low or hang dry. Check the seams at half-term. A loose seam repaired with a needle in October means the kit lasts until July.

FAQ
What colour PE t-shirt do UK primary schools usually require?
White is the most common, followed by house colour (red, blue, yellow, or green). Always check your specific school's kit list before buying. A plain white t-shirt works as a safe default if the letter has not arrived yet.
Can my child wear the same trainers for outdoor PE and indoor gym lessons?
No. Most UK schools require non-marking trainers kept solely for indoor use. Outdoor mud on white gym floors is a slip hazard, and many schools enforce separate footwear. A basic white-soled plimsoll or clean indoor trainer is enough for primary school.
How many sets of PE kit should I buy?
Two sets is the practical minimum. Most primary schools have PE once or twice a week, so one set in the bag and one clean set at home covers you when a wash does not dry in time. Three sets becomes worthwhile at secondary school where PE is more frequent.
Should PE shorts fit tight or loose?
They should fit snugly at the waist without an elastic waistband digging in, and sit just above the knee. Loose shorts are a trip hazard on gym equipment. If the waistband gaps or the leg hem drops below the knee, go down a size.
Do girls need different PE kit from boys?
In most primary schools, no. The kit list is the same for all pupils. Some secondary schools specify skorts or leggings as an alternative to shorts for girls, but plain shorts are almost always an accepted option. Check the school list specifically.
