"None the less for wear means" where no harm was made to them even after they hikes.
Explanation:
1. As the group hiked up the mountain they were fatigued but at the same time none of them had any physical harm on them on the trek.
2. This phrase also shows that the group was optimistic enough to climb the mountain and have a positive approach towards it which gave them the courage to climb that difficult cliff.
3. As the experience was dreadful and unforgettable for them, they thanked for not being harmed anyway.
