In reply to Billhook:
I got two packs of new balance short leg trunks from TK max, about £20 for 4 pairs I seem to remember. 92% polyester, 8% spandex, so very smooth and close fiting and are comfortable for any activity.
I love them for minimalist packing, as you can wash/rinse and wear and they absorbe so little that they are dry within 20 mins of putting them back on.
Also had some of the pringle (sports wear company not the addictive crisp manufacturer) trunks from TK max for a similar price, they have more cotton so aren't as quick drying. They often seem to have some of the posher pant brands in as well, if you are looking to impress the ladies, for half the price you will pay in a mans fashion outlet.
