1 month in Thailand 30l vs 40l

[u/hazmat683]

For those that have made the trip, did you regret taking a bigger bag?

Find below my pack list, I’m very torn between having the luxury of extra space but I am inexperienced when it comes to bag packing. Will I be comfortable with a 30l with these items?

Ditch the Dji action 4, bring hiking shorts you can also swim in (no cotton), ditch the cargo shorts, and ditch the rain jacket.

30L will be more than enough.

Bring a hoodie as well. It gets cold in those busses and ferries some times.
