How are the bugs on the ptarmigan? in North Cascades Posted July 28 Just did a trip with similar attributes: relatively high ridge running (wind); camping at high lakes; north cascades. Didn't really mind the bugs most of the time, but glad I had a meshed tent to chill in the evening. Could you get by without? sure. Is it worth the weight drop? I doubt it. You might consider how much of the night you anticipate being "out" of your sleeping bag... i was pretty warm at night even at 6800.
