On nice, warm days…especially in the fall and spring (but also in the summer months)…I like to work in my wood shop (garage).  I do a lot of small-detail hand work so I rarely am in any danger of splintering a leg or whatever, so I am very likely to be found out there in a t-shirt and underwear or a speedo (like this one).

This navy-blue speedo is actually one of my oldest, and most comfortable, swim briefs…and it still fits as good (maybe even better) than the day I bought it.
