I have been using my OES 12 X 15 Silnylon tarp in light gray this summer on river trips. It's light weight and ease of pitching has been great. The size has been perfect for kitchen/group shade & rain protection for 4-6 people. We did notice one issue last week on the Main Salmon river in Idaho. The tarp gives adequate shade, but we could feel the heat coming through the tarp more than we can with the heavier MSR tarps we have used in the past. Our temps were in the upper 80s to mid 90s. We mostly were camped on sand beaches, so shade was important. Would the same tarp in forest green/black/or blue give better heat resistance than the light gray? Is the heat transfer just a trade-off for the light weight & packability of the silnylon?
What say you, oh wise HF folks?????
