The simple answer to this is the number of walls. 2 vs 1. But what does it imply?

It’s not just that 2 walls keep you warmer than 1 wall in cold weather, double wall tents are known to keep you dry even better than single wall tents. This is because in a double wall tent, the fly keeps the rain and snow at bay while the inner tent expels the moist air so that it condenses on the fly (in cases ventilation doesn’t do the trick) which then drips to the ground instead of the user.

A single wall tent has to rely on one wall to do both i.e. deal with moisture from inside and outside. So the fabric has to be waterproof and breathable. Breathable fabrics may not be enough to battle condensation effectively so you have to rely on venting.

The upside to single wall tents is that they’re lighter and less bulky. Double wall tents have more parts and hence heavier and bulkier.

If we don’t take care of the earth, there will be no more that it can offer to our children. That’s why environmental protection is one of the key values guiding the development of new ADVANSA products.

In case you didn’t know, ADVANSA is a well known fabric manufacturer in Europe and also the leader in polyester fabric technology.

The textile giant will launch two new ranges of high-end technical insulation products for sleeping bags and apparel. Both ADVANSA Thermo°Dry for sleeping bags and Thermo°Cool for apparel provide an excellent level of performance.

The two revolutionary fabrics are a result of ADVANSA’s extensive experience in developing high performance fabrics for insulation and moisture management in clothing.

The performance of a fabric is determined by the combination of different fibers and design. ADVANSA’s high-end fabric not only provides insulation but also deals with the effects of perspiration, condensation and humidity inside the sleeping bag or clothing. So instead of wearing one layer for insulation and another layer for moisture management you only need to wear one layer that does both.

The dual functionality of ThermoºCool makes it the top choice for many European brands. The fibre is designed with increased surface area and microchannels to transport moisture quickly away form the skin to the textile surface. The hollow fibres allow enhanced air circulation and focus energy on the evaporation process to achieve maximum evaporative cooling.

In cool weather or after exercise the hollow fibres provide thermo-buffering to protect muscles from post-exercise chill. Thus, providing superior moisture management and temperature control, the fabrics for apparel are keeping the users comfortable across a wide range of temperatures and activity levels.

Created with new intelligent technology from ADVANSA and again meeting the two trends of growing consumer interest – multifunctionality and environmental awareness – the thermoregulation product ADVANSA ThermoºCool is also available in an ECO version. ADVANSA ThermoºCool ECO uses a polymer that is made from renewable resources, such as corn, instead of traditional petrochemical derivates.
