I'm a boxer guy but they tend to ride up undearneath my conservatively cut (read tight) uniform pants. I'd like to go Boxer briefs but the ones I bought end up riding up as well. Anyone know who makes boxer briefs that are like bike shorts in that they have that elastic down by the legs which prevent ride up? And preferabbly a brand that has a long inseam as I have long legs. Thanks and keep the ribbing to a minimal please or else negative feedback will be dispensed with extremem prejudice.
