I use Nitecore D10. It's small and light enough to fit into small pockets. Its brightness is adjustable and it uses a single AA battery which is cheap to buy. Its electronic-controlled switch is easy to operate and build quality is good.
Nitecore EX10 is another favourite. It's the same as D10 except it uses a single cr123 battery. It's a bit shorter and fatter than D10 though.
