Calida: Sleepwear, Underwear and Loungewear Fabrics, Fit and Care Explained

Calida is a Swiss maker of underwear, sleepwear and loungewear, founded in Sursee and known for soft cotton basics, pyjamas and nightdresses built to last many washes. It sells for women, men and, in some ranges, children.

A Calida order is about three decisions: which fabric suits how warm you sleep, which cut and size fits, and whether a set or separate pieces gives you better value. Calida prices sit above supermarket basics, so choosing well matters.

The fabrics, and who each suits

Calida works heavily with cotton. Fine cotton jersey is the everyday choice: soft, breathable and easy to wash. Interlock is a thicker, smoother knit that feels warmer and holds its shape. Calida also uses cotton blended with a little elastane in underwear so it recovers after stretching.

For sleepers who run hot, Calida cotton or lightweight modal-type fibres are the ones to look at, since they breathe and feel cool. For cold bedrooms, look for brushed cotton or heavier knits in the Calida winter pyjamas.

Calida has put effort into sustainability, including a range designed to be compostable at the end of its life, and product pages usually describe the fibre and certification. Read the composition line rather than the product name.

Sizing Calida pieces

Calida uses European sizing. Check the Calida size chart against your chest, waist and hip measurements in centimetres rather than guessing from a letter size bought elsewhere.

Calida pyjamas tend to be cut for comfort rather than a close fit. If you sit between sizes, the smaller one is often fine for a relaxed sleeper, and the larger one suits people who like room to move.

For Calida underwear, the fit matters more. Briefs, boxers and trunks with elastane recover well, so buy your true size. Vests and camisoles are listed with length notes; taller buyers should check the body length.

Sets, separates and the ranges that repeat

Calida sells pyjamas as complete sets and many pieces as separates, so you can pair a long-sleeved top with shorts or buy two bottoms for one top. Separates cost more per piece, but replacing only the part that wears out is often cheaper over time.

Some Calida basics return season after season in the same cut. If you find a Calida brief or vest you like, note the product name; buying the same item again later removes the sizing risk.

Seasonal Calida prints change each year and go to sale when the next collection lands. Plain colours stay in the range longer and rarely go deeply discounted.

Calida loungewear sits between the two: joggers, long tops and cardigans in the same soft cotton, meant for the sofa and a quick walk out. If you only want one Calida piece, a loungewear top that doubles as a pyjama top gets the most wear for the money.

Gift buyers do best with Calida nightdresses or pyjama sets in a relaxed cut, where an exact size matters less than it does with underwear.

Washing Calida so it lasts

Calida's reputation rests on items lasting years. Follow the label: most Calida cotton pieces wash at moderate temperatures, and lower is kinder to elastane and colours.

Turn prints inside out, wash like colours together, and skip fabric softener on underwear with elastane, since it can shorten the stretch. Line-drying keeps Calida cotton from shrinking; if you tumble dry, use a low setting.

Expect a slight shrink on the first wash of pure cotton. That is one reason the relaxed Calida pyjama cut is forgiving.

Delivery and returns

The Calida site ships to many countries from Europe, with costs and times depending on the destination. Buyers outside the EU and Switzerland should check whether duties are included or charged on arrival.

Underwear is commonly excluded from returns once worn or unsealed for hygiene reasons. Check the current Calida return window and conditions before ordering several sizes to compare.

Where the Calida savings are

The 20% Calida code is the strongest on most baskets. Try it first on a pyjama set or several underwear pieces.

The $20 code beats 20% on any Calida order under $100, and beats the 10% code on anything under $200. It may carry a minimum spend or a seasonal date limit, so read the terms when you enter it.

Keep the 10% Calida code as a fallback if the others have expired. Codes generally do not stack with each other or with sale prices, so compare a marked-down Calida item without a code against a full-price item with 20% off.

Many welcome codes are single-use and tied to a newsletter sign-up. Put your full Calida basket together before entering one.

Common questions

Does Calida sizing run large?

Calida pyjamas are cut relaxed. Underwear is closer to true size. Measure and use the Calida chart.

Which Calida fabric is best for hot sleepers?

Fine cotton jersey or lighter smooth fibres. Avoid brushed cotton and heavy interlock in summer.

Will Calida cotton shrink?

Slightly on the first wash if washed hot or tumble dried. Wash cooler and line-dry.

Can I return Calida underwear?

Usually only unworn and in original packaging. Check the current Calida policy first.
