How to pack for lightweight trekking

New or old in the trekking game, it can always be a bit challenging to decide what to bring. Spending more time in the mountains than most people (and probably goats), we thought mountain guide, alpine skier and trail runner Guiliano Bordini was the perfct guy to grab a few tips from. 

1. Antibac wipes
2. Light weight and breathable gloves
3. A lighter
4. A water bottle with some sports tape wrapped around 
5. Fast drying, merino wool mix running socks 
6. Hip pack for easy and light weight storage
7. Phone in a waterproof bag
8. Light weight, flexible and very breathable shorts
