I purchased this specifically for summer use in my WBRR hammock. I have the Downmat 7 UL LW for the colder camp trips. The wider models do well at keeping the proverbial hammock cold shoulders at bay whilst in a hammock. Tonight I am going to assess my Arrowhead underquilt with a Exped regular Synmat 7 at around 15* to see if this is the sleeping system I want to take on the AT thru-hike in 2016...fingers crossed...gear systems tests underway. I really want to hang the AT.
