Diamir Down Sleeping Bags
The Diamir down sleeping bags raise the sophisticated Baltoro shell design to a new level by the use of PHD's exceptional 800 down and inner Drishell panels at head and foot. The Diamir represents the new bench mark for down sleeping bag standards.
900 down is now an option on the Diamir bags. This option extends the range of these bags by up to 10 degrees C, while keeping the weight the same.
MX in now the inner fabric on all Diamir bags. The inner Drishell panels at head and foot are still there, but introducing superlight MX as the main inner has reduced the bag weight by over 30gm.
Design Details include:
- Wind and water resistant Drishell outer
- Drishell inner panels at head to protect against breath soaking the down
- Drishell panels at inner foot to cope with damp feet/footwear
- Full length zip (left or right) with double draft tube
- Side V channels: Down filled channels along each side ensure insulation and extra outer/inner differential allows full loft
- Cowl hood: Close fitting with drawcord
- Collar: Wide 3D collar in Drishell with drawcord
- Footpiece: Ovoid shape to fit naturally to feet & avoid pressure; multibox section covers whole foot area
