Frequently Asked Questions
Should I size up or down for these tanks?
Check each brand’s chest measurement chart — LAPASA cotton items have reports of running small and some shrinkage, so size up if you prefer a relaxed fit or plan to use warm drying. Performance blends like Pair of Thieves have more stretch and usually fit closer to advertised sizes.
Are performance blends better than 100% cotton for summer?
It depends on use: 100% cotton breathes naturally and feels soft against skin, while performance blends add moisture-wicking, faster drying, and stretch that help during travel, workouts, and humid days. For a polished layered look with active comfort, choose a performance blend.
How do I keep tanks from shrinking or fading?
Wash cold, use gentle cycles, and air-dry or tumble-dry low. Avoid high heat and harsh detergents; turn darker colors inside out to reduce fading. Following care instructions helps preserve fit and color, especially for cotton multipacks.
