I picked up a BD Hilight last Spring, but haven't used it yet. I got it to use in early Spring and early to late Fall. I have read mixed reviews on the material, so I have been a little leery about using it, plus, after seam sealing it, I found out it weighted 3.5 lbs. not 2.5 as its trail weight was listed. If I had weighted it before I spent hours seam sealing, I would have returned it to REI. I thought packaged weight included the box it was packaged in and so forth.
