Background: I wear a pair of shorts for trekking in the day but want something clean to put on when arriving in camp. What do people use for wearing in camp and sleeping? Anyone got any hidden gems I'm looking for something that: 1. covers ankles 2. doesn't need a belt 3. is comfortable to sleep in 4. weighs less than 200g 5. isn't waterproof (6. vaguely wearable in public!) Looking forward to hearing your ideas. Thanks!
