Man it’s tough to say. I’ve never tree stand hunted with them.That is correct.
I’ve worn this combo down to almost freezing with little to no wind. But I wouldn’t sit comfortably very long that way as the insulation isn’t there.How low of temps can you wear the Obsidians with a warm baselayer?
Here are the pieces I actually used - northern MN. Highest temp was 40ish, lowest was -10.Get the Sanctuary Set, at least the bibs. Solitude might work if you like lots of layers. At twenty degrees and windy, you will need a lot of layering with solitude as they are not windproof. Carry the sanctuary in or walked bibs unzipped.
