Endura cycling 'boxers'

[Jezston]

I have some but never got on with them as fit was a bit baggy around the waist but tight around my huge, gelatinous arse.

FTFY.

Try these:
Bamboo boxers with removable pads

Tried out the Tenn padded boxers @ £10.49. Pad looked a bit thin but absolutely no discomfort on a 90 mile ride on NCR 81 to Aberystwyth (rough roads, hills & forestry tracks) so I've bought another pair - they've gone up to £11.99 though.
