Deuter 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, while 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.
The Astro Pro 400 is ideal for temperatures between -4 to -20°C
