Product Insights
The I.FIV5 Long-Sleeve Perforated-Back T-Shirt uses a close-fit bellows effect to expel hot air through back perforations, aided by raglan sleeves and a wicking athletic fit for HIIT and weightlifting, while Polygiene anti-odor treatment permits several days of use between washes, reducing environmental impact by a third when skipping every other wash, though the perforated back may reveal skin or a sports bra, and care requires cold gentle washing without fabric softener and low heat drying to preserve the treatment; the shirt is made of 88% recycled polyester and 12% spandex, offering the same odor-control technology as Patagonia and Arc’teryx for $49 CAD, a $9 premium over a basic UA Tech but with four performance upgrades.
