Our sleeping bags for professionals are also bluesign® products with RDS-certified down! They are guarantors of regenerative sleep on demanding trekking or mountain tours. The inner sleeve wraps gently around the sleeper thanks to elasticated chamber stitching to effectively prevent the formation of cold spots. Inside the outer sleeve the inner sleeve can expand by up to 25% in width to create more space inside the ASTRO PRO models. The pronounced differential cross-section allows the down to achieve its full loft potential. Longitudinal chambers situated below the knees prevent the down from sliding to the side to guarantee outstanding heat insulation. In addition, the sensitive area around the feet is kept warm by a three-dimensional foot box with an especially comfortable filling.Details:
|Usage:||Range of temperature|
|Information for ranges||Comfort||Crossover||Risk|
THE COMFORT RANGE is based on the lowest temperature at which a ‘standard’ woman (25 yrs. / 60 kg / 160 cm) can expect to sleep comfortably in a relaxed position. This range ensures a comfortable sleep, also for inexperienced users.
THE LOWER LIMIT is based on the lowest temperature at which a ‘standard’ adult male (25 yrs. / 70 kg / 173 cm) can expect to sleep comfortably in a relaxed position. An experienced user can optimise the insulation qualities by his choice of clothing and further factors.
EXTREME is a survival only rating for a ‘standard’ adult woman. She can remain for six hours without sleep. Without risk of death from hypothermia, but with a risk of other damages to health (such as frostbite).
Opposing diagonal trapezoid pockets ensure the down is stabilised. Cold spots are thus avoided which is the best way to guarantee warmth insultion.
