Trees help us fight climate change by absorbing carbon dioxide from the atmosphere that causes global warming. That's why we plant one tree for every garment to neutralize our carbon footprint.
LOVE the fit, just like all the other shirts, soft cotton, stretchable and comfy. Usually a medium in most but with Proto101 the small fits perfect. I’m 5’11” 180lbs.
I don't own a lot of tank tops, but I'll be buying this one in another color -- it's so good! High quality, soft material, comfortable fit.
Love this shirt. Super comfortable and like how it looks. These guys do a great job.
Was honestly really surprised with how well it fit and how great it feels. Slightly heavier than normal tanks but that’s only cause the quality is so good
