for a very light, durable, bare bones sleep system, including shelter, eVENT bivy (Mountain Laurel Designs), small
sil tarp (the eVENT is waterproof, but in the event of rain/snow a small tarp is nice!), XTherm pad (if worried about punctures- a Z-Rest), an Apex quilt rated to 20-ish degrees- the bivy adds an easy 5 degrees of warmth
boom- done
