I would not take a glider OUT of the house NOT in a zipped up tight bonding pouch unless you felt 1000% percent confident he will come back or not run off. One mistake and glider could be gone.
That being said we do have 2 out of 10 that my wife will take out in her shirt, a place he usually wont come out of even IN the house all day. And both of these two we can hold in our hands and handle with no issues. Unlike some of the others if they do try to explore in the house, they are very easy to pick backup.
Some of our gliders have been very slow to bond, some are just more resistant to trust such large scary humans. Others have bonded stronger and faster.
