Sleeping bag constructions

Creating optimal temperature regulation

A sleeping bag should have an as optimal fit as possible in order to avoid any unnecessary heating of air. All our sleeping bags follow the so-called mummy shape, where the silhouette is based on an average sized person lying on his/her back.

The models then have individual fits, based on the activity for which they are intended. For example, our warmest sleeping bags have a more generous fit to allow space for extra clothing.

In order to optimize the sleeping bags for respective usage areas we make use of different insulation constructions, and to be able to regulate the sleeping bag climate, different zipper solutions.

We use as clean and simple a fit as possible in order to avoid unnecessary seams or constructions, and each detail is carefully considered so as to optimize its purpose.

We have a few different ways to construct our baffles, some for down and some that are better suited for syntethics. Down needs to expand to create the so-called loft and to be able to insulate effectively.  For these we use: box or a trapezoidal construction. For syntethics we use: quilt, offset or shingle. Take a look in the slider to get the full picture.

All our zippers are ergonomically designed and positioned based on special needs during different activities.

SYNTETHIC SLEEPING BAGS – When the conditions are wet, cold or warm.


Synthetic insulation is polyester fiber. There are several positive qualities with synthetic filling, for example being able to insulate in wet conditions and costing somewhat less than down. So if you are planning to spend a lot of time in a damp environment and want a sleeping bag that is easy to manage, then choose from our synthetic range.

We use our own synthetic materials, QuadFusion™, QuadFusion+™ and Trifusion®. QuadFusion™ is a family of high quality synthetic insulations. All QuadFusion™ insulation options stay warm also when wet, provide lightweight, efficient warmth on the coldest days and offer easy to care for, packable products. QuadFusion™ is made completely from bluesign®-approved, recycled and recyclable polyester.

Using a middle layer of state of the art crimped hollow fiber, sandwiched between two outer layers of multichannel fibers with excellent wicking capacity the QuadFusion+™ is a great alternative for a range of activities where you need a thermal barrier as well as the ability to keep dry.

Besides the outstanding warmth to weight ratio of this insulation, QuadFusion+™ wicks over 45% better than other performance insulation options and evaporates moisture over 50% better than other performance fabrics tested. Warming you when you are cold, cooling you when you feel hot.
Recycled content: 100%.

Quadfusion™ is our versatile homogenous insulation alternative. The great warmth to weight ratio is achieved by using hollow-fiber that is crimped into a spiral shape – maximizing the air-trapping ability and subsequently the warmth, while at the same time keeping the weight down.
Recycled content: 50%.

Lightweight Polyester-fiber insulation with a mix of three different types of fine denier hollow fibers giving warmth without bulk. The fiber mix is fused together into a durable insulating 3D-web via melt bonding. The result is very good insulating properties at a low weight


DOWN SLEEPING BAGS – When the conditions are DRY, cold or warm.


Down and feathers are natural fibers that come from ducks or geese. A down cluster has a natural ability to trap air, and once this trapped air is still, it is able to take on the body’s temperature and allow heat insulation to work.

Both down clusters and feathers are combined in down products. This ratio is described as, for example, 90/10, which means that the bag contains 90 per cent down and 10 per cent feathers.

Fillpower is the space a specific amount of down creates when allowed to reach its maximium loft. This is done with a specific test method.

Fillweight is the amount of down placed inside the sleeping bag. Down insulates a lot of heat in relation to its weight, and is also very lightweight. The disadvantage is that it loses much of its insulating capacity in wet conditions.

The materials we work with must be functional and environmentally friendly. We already have this in mind at the early design stage of a product: how do we position the pattern to ensure as little wastage as possible, can we use material that is already in production, can we coordinate use of material within other business areas of the company? These, together with many other measures, both large and small, are taken by us in the creation of not only sleeping bags, but all our products. All our sleeping bag materials include the following factors:

bluesign® is a voluntary initiative for textile manufacturers to improve their production to the highest environmental standard available. When we choose a bluesign® approved fabric we are sure that it meets our high demands on function, environment, health and safety. A Haglöfs carrying the label bluesign® product is made from a major part of bluesign® approved materials.

Recycled fabrics in our products can contain post consumer recycled materials (PCR) eg, PET bottles, post internal recycled materials (PIR) eg, in-line spills from the textile manufacturing process and industrial plastic waste.

Hypo Allergy (Allergy-free) down is passed through a rigorous washing process to remove all particles of dirt and dust mites. The minimum value required to call down Hypo Allergy is 450, but Haglöfs only uses down with a value of at least 1,000. 

This means that we use the cleanest down on the market. Read more about measurement and test methods at www.idfl.com

Haglöfs only uses down that is a by-product of the food industry. Our down is traceable back to the slaughterhouse, which means that the birds are never force-fed or plucked alive.  Inside each sleeping bag is a number on a sewn-on patch used for tracing purposes.
