Trekking Peaks |
All three Systems combine clothing warm enough for the summit with lightweight Hispar sleeping bags. 'System 1' shows the lighter bag (Hispar 400) with the warmer clothing (Hispar). In Systems 2 & 3 it’s the warmer Hispar 500 bag with the lighter Rondoy clothing. All three options offer more than enough warmth, day and night. |
| The Hispar clothing is rated for -30°C daytime use, well warm enough for your peak. Wear it inside the lightweight Hispar 400 and the combination will take care of your nights right down to -29°C. This system is based on a lighter bag and warmer clothing than System 2: overall performance is similar. |
| The Rondoy clothing is rated for -20°C daytime use, warm enough for your peak. Wear it inside the Hispar 500 and the combination will take care of your nights right down to -33°C. This system is based on a warmer bag and lighter clothing than System 1: overall performance is similar. |
| The simple Filler bag boosts the Hispar 500 to -25°C performance in this system. But it can also double up with the Rondoy jacket to take the rating to below -30°C, as well as working as an emergency item on the climb. |
