Duvet Togs: A Buying Guide

What Does ‘Duvet Tog’ Mean?

‘Tog’ stands for thermal overall grade. In plain English, it measures how well a duvet traps heat. The higher the tog, the warmer the duvet. 

A low-tog duvet will feel much lighter and cooler, making it better for warm summer nights or for those hot sleepers. A higher-tog duvet retains more heat, making it much better for cooler nights or for anyone who likes to feel more properly cocooned. 

All duvets use the same term ‘tog’, regardless of what materials are put inside the duvet. That's why, as with most things, it's not as simple as it might seem.  The filling matters greatly, and its weight and density will vary depending on the materials used, which may not meet your preferences. A 4.5 tog wool duvet, for example, won’t weigh or feel the same as a 4.5 tog synthetic duvet.

Duvet Tog Ratings Explained

Most duvets sit somewhere between 1 and 15 tog. With a lot of tog choices available, you could be forgiven for thinking you should buy a different duvet for every season, but as long as your duvet is well-made and breathable, you’ll be able to use it across a number of temperatures.

Here is the tog rating breakdown: 

The usual good ‘all-rounder’ often seen is a 10.5 tog duvet. This would suit most people if your bedroom temperature stays fairly consistent year-round. If your home gets too hot in summer or too cold in winter, one duvet might not be the perfect answer for every month.

What Tog is Best?

We recommend having a duvet for each season, as they will last for years with proper care. In the peak of summer, it's best to stay cool, so opt for something in the 1-4.5 tog range. In the midst of winter, you’ll likely need something a bit more substantial, so opt for a tog rating between 12 and 15. At Rise & Fall, we believe comfort should feel natural, not stuffy. Our premium Wool Duvet is made with 100% british wool and is naturally breathable, helping to regulate temperature year-round.

Duvet Fillings Explained

Choosing the right tog for the season isn’t always the answer if you don’t take its filling into account. You might still find that your 4.5 Tog feather duvet is too hot, and that's because it's designed to retain heat.

The best all-round duvet filling is wool, as it's naturally breathable, moisture-wicking and hypoallergenic.

Here’s our duvet filling guide:

What Duvet Filling is Best?

There is no single ‘best duvet filling’ for everyone, as the choice really depends on how you like to sleep. If you like something gently weighted, you might opt for a British Wool Duvet; if you prefer something warmer, you might opt for a premium Recycled Down Duvet.

Synthetic duvets can be practical and easy to care for, but they don’t often share the same breathability and longevity as their natural counterparts. 

At Rise & Fall, we believe better sleep starts with better materials. That’s why we recommend choosing a high-quality duvet made with natural, breathable fibres, which help to regulate your temperature year-round.

2. Damask Linen

The second type is damask. This linen represents the pinnacle of weaving artistry, featuring intricate patterns hand woven directly into the fabric using a jacquard loom. This reversible weave creates subtle, elegant designs that catch light beautifully, making it perfect for formal table linens. This is a complex weaving process that results in a fabric with a sophisticated, lustrous finish that’s best elevating dining spaces.

3. Gauze Linen

Loosely-woven linen, or gauze linen, offers maximum breathability and a more relaxed, casual feel. The open weave structure allows air to circulate freely, making it excellent for warm-weather clothing, such as lightweight scarves and summer dresses. While this weave does sacrifice some durability we find it incredibly comfortable to wear.

4. Towelling Linen

Small loops are woven into linen offering superior absorbency and resistance to bacterial growth. This makes it ideal for bath towels and robes.

5. Sheeting Linen 

This is specifically woven for bedding applications, balancing smoothness with breathability. This weave creates fabric that's substantial enough to withstand regular washing while remaining soft against the skin. The careful balance in thread count ensures linen bedding is both durable and comfortable.

Linen Types: By Fibre Composition 

The thread composition of linen fabric significantly impacts the way it behaves and feels. From modern blends to trusted original compositions - there’s a variety of ways in which linen can benefit your lifestyle.

1. Organic Linen 

This is produced from flax grown without synthetic pesticides or fertilisers. It retains the natural strength and breathability of flax fibres while supporting lower-impact farming practices.

Our Men’s All Rounder French Linen Trouser, however, highlights the best of organic linen blended with cotton to help shape the drape and enhance the trouser’s versatile style.

2. European Flax™ Linen

French linen, particularly from Normandy, holds special significance. The region's maritime climate, with its consistent moisture and moderate temperatures, creates ideal conditions for growing flax with exceptionally long, strong fibres.

European linen production is regulated under strict environmental and labour standards, ensuring that every step of the process meets high ethical and quality benchmarks. Flax grown in Western Europe is traceable, low-impact and long-lasting, making it the preferred choice.

At Rise & Fall, we use European flax™ linen in our men's linen collection and women's linen apparel as well as our Relaxed & Refined and House of Grey bed linen ranges, ensuring our customers receive the finest quality available.

3. Modern Blends 

Modern blends represent the evolution of linen textile technology, combining flax fibres with other natural or synthetic materials to enhance specific qualities. At Rise & Fall, we only focus on thoughtful blends that elevate the linen experience, like our linen and TENCEL™ Lyocell combination in our womenswear. This blend creates fabric ideal for modern wardrobes that demand both comfort and sophistication, reducing wrinkles while maintaining the essential character of linen.

We've also introduced Ramie material to our women's linen collection; a renewable and biodegradable plant fibre derived from the nettle family. This eco-friendly addition shares similar properties to traditional linen, offering durability, breathability and superior moisture-wicking capabilities but with a slight added lustre. Ramie can be woven into fabrics with a similar feel and drape to linen, as seen in our Ramie Gauze Tunic Dress and Ramie Gauze Aegean Dress. 

Linen blend fabric can dramatically alter linen properties depending on the blend percentage. A small amount of elastane might add stretch and wrinkle resistance, while cotton blends can increase softness, as seen in our men's linen collection. See below how these combinations allow for seasonal, lifestyle and design versatility:

How to Distinguish High-Quality Linen

High-quality linen can be identified by its weight, fibre length, texture and origin.

• Weight serves as one of the most reliable indicators of linen quality. Premium linen fabric feels substantial and weighty yet remains breathable and comfortable. Lightweight linen might feel insubstantial and is more likely to be made from shorter, lower-quality fibres.
• Strength is another crucial factor. Quality linen should feel strong and resilient when handled, with minimal loose threads or weak spots. When you gently pull on the fabric, it should resist stretching and return to its original shape.
• Natural creases and imperfections are actually signs of authenticity in high-quality linen. Look for subtle irregularities in the weave and slight variations in texture, these indicate genuine flax fibre rather than synthetic alternatives. The natural slubs and slight thickness variations are hallmarks of authentic linen textile.
• Softness in quality linen develops over time, but even new pieces should have a pleasant hand-feel. Premium linen will soften significantly with each wash, becoming more comfortable. This improving quality distinguishes genuine linen from inferior alternatives that may become rough or lose their appeal over time.
• Origin matters significantly when evaluating linen quality. As mentioned, European flax™, particularly from France, Belgium and the Netherlands, consistently produces superior results due to ideal growing conditions and traditional expertise.
• Long-staple fibres create better fabric quality because they result in fewer joins or weak points in the yarn.
