Buying thermals for men online

Thermals for Men go under what you were already going to wear and add warmth without adding bulk. A matched top and bottom is the simplest way to stay comfortable through a cold spell.

At Underlinen you can buy thermals for men online from FCUK and PUMA. The range also covers Thermal Tops, Thermal Bottoms and PUMA Thermals.

Size a thermal snug: it works by sitting close, and air gaps are what let the warmth out.

Why it matters

What a good thermal actually does

Thermals are the essential starting point of winter warmth. Bang on warmth and indispensable comfort when cold weather sets in. Whether you wear a shirt, T-shirt, sweatshirt or heavy jacket, thermal is the base layer that stays inside, locking in body heat and shielding you from the chill. A thermal top and thermal pant worn together keep you comfortable through cold mornings, North India winters and cold-weather travel.

// WARMTH WITHOUT BULK

Warmth without bulk

A thermal goes under what you were already going to wear. You get the warmth of another layer without looking like you are wearing one.
// WORKS INDOORS TOO

Works indoors too

Cold offices, early flights and long drives in air-conditioning are where most people are actually cold, and a thermal handles all three.
// TRAVEL-READY

Travel-ready

One thermal set packs flat and covers a hill station, a north Indian winter or a trip abroad without a second suitcase.
// LAYERS UNDER ANYTHING

Layers under anything

Under a shirt, a jacket or a sweater: a thermal is cut to sit close so whatever goes over it still fits.
The buying guide

How to choose Thermals for Men

Choosing thermals is about layering: A quick, honest guide so you buy once and buy right.

// FIT

Fit

: thermals work by sitting close to the skin, so size for a snug base layer rather than a loose one.
// TOP AND BOTTOM

Top and bottom

: a matched set holds warmth across the whole body; most people start with the top and add the bottom for genuinely cold weather.
// LAYERING

Layering

: a thermal is meant to sit invisibly under what you were already going to wear, so it works with a shirt, a jacket or a sweater over it.
When to wear it

When you actually need thermals

Same category, different jobs. Here is where each one earns its place.

// A NORTH INDIAN WINTER

A north Indian winter

Under a shirt or a jacket from December onwards, indoors and out.
// HILL STATIONS AND TRAVEL

Hill stations and travel

One set covers a week away without packing a second jacket.
// COLD OFFICES AND EARLY FLIGHTS

Cold offices and early flights

Air-conditioning and 6am departures are where most people are genuinely cold through the year.
Sizing

Getting the size right

Size is the one thing worth getting right before you order. Three things that make it a one-time decision.

// SIZE AS A BASE LAYER

Size as a base layer

A thermal is meant to have your normal clothes over it, so size it to sit close rather than loose.
// MEASURE THE CHEST

Measure the chest

Take the tape around the fullest part of the chest and read the chart against it, not against your shirt size.
// TOO LOOSE DOES NOT WORK

Too loose does not work

Air gaps are what let warmth out. A thermal that moves around is doing half the job you bought it for.
Care

Making them last

Most innerwear does not wear out. It gets washed out. Six habits that add months to anything in this range.

  • • Wash cold and on a gentle cycle.
  • • Dry flat. High heat flattens a thermal, and flat is exactly what takes the warmth out of it.
  • • Skip the tumble dryer entirely for this one.
  • • Keep softener off it: it coats the fabric and works against what you bought it for.
  • • Store folded rather than hung, so the shape holds between winters.
  • • Air it out at the start of the season rather than washing it straight away.
