The ever resourceful Valet. turns our attention to Portland, OR-based Columbiaknit — the original suppliers of rugby shirts to Lands’ End and L.L. Bean. Today, Columbiaknit produces “private label goods for some of your favorite brands,” writes Valet — but it’s not say which ones. “Actually built for the pitch, [these shirts] sport functional details like gussets under the arms, rubber buttons and narrow collars that stand up for themselves, unlike most wimpy polos.” Retail price: $36. Sold.
