Product Description
The Defence 4 is the most popular and best-selling all-round sleeping bag with excellent weight to stuff size and performance ratio. It is a well-established, three season sleeping bag that has proven to be 100% reliable on cold nights both in the wilderness and in snow caves. A protection flap on the outer side of the zipper keeps out wind and wetness.
The outer shell is a super-light, highly resistant, microfibre nylon with a fine microporous coating which makes it waterproof. There is a generous draft tube on the inside of the zipper to prevent heat loss at the zipper.

G-LOFT ISO+ FILLING
Manufactured from high-quality bi-component polymers, the structure of G-LOFT insulation is in fact similar in many ways to high-quality goose down. The 3-dimensional crimping ensures maximum resilience and loft.
DIFFERENTIAL CUT
Even when the sleeper moves about compressing the inner layer of insulation, the sleeping bag’s warmth is retained. Successive insulating layers are cut more generously. This ensures the greatest loft in all areas and in every position. Additional air cushions form between the various layers. Movement inside the sleeping bag creates pressure points, but with our differential cut only the innermost layer is compressed. The outer layers retain their loft and therefore their insulating properties.
THERMOFLECT
Thermoflect increases the heat retention of a sleeping bag by around 11 %. Thermoflect is our solution to heat loss due to body radiation. Thermoflect is an ultra-light, ultra-soft, breathable scrim with the unique ability to reflect body-heat.
THE TRAPEZOIDAL FOOT SECTION
Experience has shown that the trapezoidal cut provides the ultimate foot space. In a normal sleeping position, the feet do not poke the insulation outward, avoiding cold spots. There is also enough room to store a shoe bag or extra clothing.
DOUBLE-LAYER SANDWICH CONSTRUCTION WITH LOOSE SHELL
Two G-LOFT Plus insulation layers are arranged in such a way that the quilting is offset. The shell is attached afterwards, creating a further layer of air between the quilted insulation and the shell. With no stitch perforations in the shell, it is relatively water and airtight.
COMBINABLE SLEEPING BAG SYSTEM
This sleeping bag can be combined with the Tropen to make a sleeping bag system. Such a system can be used as a 4 Season Sleeping Bag and allows you to carry only the weight and the bulk necessary for the prevailing temperatures.
