A ‘sleep system’ encompasses everything that a person uses to sleep. The main components might be a foam pad, inflatable pad, sleeping bag or quilt, bag liner and any clothing or accessories used to provide extra warmth or comfort, such as clothing, down hood, pillow, etc.
My system in Spring will comprise:
- Adventure Medical Kits Sol Emergency Blanket (70g / 2.5oz). Multi-purpose, it obviously can act as an emergency heat-preserving blanket but will be used every day underneath the inflatable pad to provide a thermal insulation boost and add slight protection to the pad from thorns, cones, etc.
- Exped SynMat UL 7 inflatable sleeping pad (460g / 16.2oz) with potentially an Exped Schnozzel Pumpbag or Pillow Pump to inflate it and sleep on (to be tested first)
- Zpacks 20f / -6c sleeping bag with 850 fill hydrophobic down (582g / 20.5oz)
- LifeVenture silk sleeping bag liner (140g / 4.9oz) – I had them confirm to me that their EX3 system has Permethrin as the main ingredient)
- Icebreaker longjohns for the lower body (185g / 6.5oz)
- One of my normal upper body clothing layers
- Zpacks goose down hood (37g / 1.3oz) since the sleeping bag has no hood or draft collar. The hood is a multi-purpose item as I don’t then need a hood on any insulation layer.
In summer I will switch to a lighter sleeping bag and send the down hood back to base and either switch to a lighter fabric long-johns such as Patagonia Capilene 1 Silkweight or just go without.
