Product Insights
The I.FIV5 Ultra-Soft Jersey Crew-Neck Sweatshirt delivers breathable, moisture-wicking comfort from a buttery-soft 92% recycled polyester and elastane jersey with permanent Polygiene odor control that reduces washing, extending fabric life. Raglan sleeves provide 25-30% more arm range of motion and reduce chafing, while the garment is sustainably crafted with recycled silver and boasts bluesign, Oeko-Tex, and REACH certifications. Priced at $59 CAD, it rivals Under Armour in quality and features, fits true to size or comfortably oversized, resists pilling, and comes in a five-color palette that encourages repeat purchases. The main tradeoff is that lighter colors (Ivory and Mossy Green) may show slight sheerness during movement or stretching.

Perfect Sweatshirt
This sweatshirt fit perfectly and the fabric is warm, but cooling at the same time. It hangs exactly how I wanted it to and washed well. I even went back and bought additional colours! For reference I vary between L—if it’s a bigger fit and XL when it’s smaller or I want a looser style. I went with XL for this shirt, which was perfect.
