Baby thermal inner wear: does your baby need it this winter?
When a baby needs a thermal inner or vest in a Pakistani winter, city by city, how it should fit, and how many layers go on top so they stay warm, not hot.
The short answer
Most babies in Pakistan don’t need a special thermal for ordinary winter days indoors. A soft long-sleeve vest or bodysuit under a knit set, with socks, is usually enough in a room that is reasonably warm. A thermal earns its place when the house is cold, the gas has gone, you are out at night, or you live in Islamabad, Quetta or further north.
Think of a thermal as a better base layer, not an extra one. On a cold day it replaces the everyday vest; it shouldn’t go on top of everything else your baby is already wearing.
Thermal, vest or bodysuit: what’s the difference?
A thermal is made to be warmer than an ordinary vest, which is the whole point. It also means a thermal, a thick knit set, a sherpa jumpsuit and a blanket together can be far too much in a heated room: if the thermal goes on, take something else off. Our post on what to wear under a baby knit set covers the everyday base layer in more detail. Here is how the three differ:
- Thermal: a close-fitting top and leggings, or a one-piece, usually in a waffle or brushed knit that holds a thin layer of warm air against the body. Shops sell it as ‘thermal inner’, ‘thermal suit’ or ‘winter inner wear’.
- Vest (banyan): a thin, plain top, sleeveless or with sleeves, worn next to the skin all year round.
- Bodysuit: a vest that snaps under the nappy, so it stays put when the baby is lifted, rolls or crawls.
City by city
Use the city as a rough guide, but remember that the room matters more than the map. A baby in a gas-heated room in Quetta may need fewer layers than a baby in an unheated flat in Lahore during gas load-shedding, and the moment the heater goes off and the house starts to cool is when a thermal makes the most sense. Roughly:
- Karachi: winter nights usually stay above about 10°C, dipping lower only in short cold spells, and the days stay mild. A thermal is seldom needed, except for a late outdoor function in January or a trip up north. See does a baby in Karachi need winter clothes.
- Lahore, Faisalabad and Multan: in late December and January, nights often drop to around 5°C, with thick fog and damp air. A thermal helps for early-morning outings, night weddings and houses without heating.
- Islamabad, Rawalpindi and Peshawar: nights can get close to freezing. A thermal under day clothes is useful in the coldest part of winter, especially in older houses with tiled or marble floors.
- Quetta, Murree and the northern areas: nights go well below freezing. Here thermals are a normal part of the base layer, indoors as well as out, with a properly warm outer layer for going out.
How a thermal should fit
- Snug against the body but not tight: no red marks at the cuffs, neck or waist when you take it off.
- Flat seams, and an envelope neckline or shoulder snaps so it slips over the head without a struggle.
- Long enough in the body to stay tucked in, or a bodysuit style that fastens under the nappy.
- The size your baby wears now. A thermal bought a size up sags, and a loose thermal doesn’t hold warmth where it should.
- Soft on the inside, with no scratchy labels. If your baby has eczema or sensitive skin, ask your doctor what suits them.
What goes on top
On a cold day, the layers might be a thermal, a two-piece knit set and socks, plus a cardigan or hooded jumpsuit only for going out. The Charcoal Waffle-Knit Henley & Jogger Set is wool, so over a thermal it suits the coldest days; on milder days it goes over an ordinary vest instead. The Sage Cable-Knit Teddy Sweater & Jogger Set is a thick, textured knit, so pair it with a thin vest unless the room is genuinely cold. Thinner sets from our baby sets work over a thermal when the house is chilly but the sun is out.

Thermals and sleep
Night is when babies are most often over-dressed, because the room cools and parents add layers to make up for it. The NHS and The Lullaby Trust advise checking a baby’s temperature by feeling their chest or the back of their neck, not their hands or feet, which often feel cool anyway. If the skin is hot or sweaty, take a layer off.
A thermal under a sleepsuit can be right for a cold, unheated room, but not with a thick knit set, a blanket and a razai on top as well. Babies shouldn’t wear hats to sleep indoors, and loose blankets and quilts don’t belong in the cot. For night layers by room temperature, see our guide to dressing a baby for winter in Pakistan. If you are worried about your baby’s temperature, speak to your doctor.
Quick answers
Can a newborn wear a thermal?
Yes, if it is soft, fits well and the room is cold. Newborns can’t control their temperature as well as older babies, so check their chest or neck often and take a layer off if they feel hot. In a warm room, an ordinary vest is enough.
Should a thermal go under eastern clothes at a winter wedding?
It can, especially at an outdoor or lawn function, because a thin thermal sits flat under a kurta or frock. For a heated hall, skip it or choose a light one, since a thermal is hard to remove mid-evening; let a cardigan be the layer that comes off.
How many thermals does a baby need?
Two or three in Lahore, Islamabad or Peshawar, so one can be in the wash. In Quetta or the north, where they are worn most days, four or five. In Karachi, one is usually enough for trips and the odd cold night.
