DropTemp® Dry Cotton (2 Pack)

Wore this through a 90-degree commute and the underarm panels kept my shirt noticeably drier than my old cotton v-necks. The cotton itself is soft without feeling flimsy, and the v-neck hasn't stretched out after several washes.

The underarm insets actually do something — after a humid commute I checked my shirt and there was barely a mark. The cotton's soft enough that I forget I'm wearing it under a dress shirt.

Wore this through a long day of meetings and the v-neck stayed put without gaping at the collar. The dry cotton feels lighter than my old undershirts, though I wish the pack came in more colors.
