How much to pack for a weekend
Short answer: Two sets of underwear and socks, two tops, one bottom and one set of nightwear. That covers two nights without you having to wash.
The list
For two nights and three days: two pairs of underwear or briefs, two pairs of socks, two t-shirts or tops, one extra pair of trousers and one set of nightwear. What you wear as you leave does not count.
What makes the list shorter
Choose a bottom that goes with both tops and keep the colours in one family. Then everything combines and you do not need an extra set just in case. See bamboo clothing for men.
Bamboo takes up little space
Bamboo fabric is thin and packs down, so two sets take less room than in cotton. That is one reason it is easy to travel with. See bamboo underwear for men and bamboo nightwear for men.
