Product comparison
Compared within this brand.
| Brushed Polar-Fleece-Lined Zipped Mock-Neck Top: Choose this if you want a warm, stretchy base layer for winter sports: the soft polar-fleece-lined jersey is made from 87% recycled polyester and 13% spandex, wicks away moisture, and uses Polygiene® technology to eliminate odour and prevent bacterial growth. It suits runners and winter athletes who want a fitted silhouette with a high mock-neck collar and short front zipper, extended thumbhole cuffs, a zip pocket, and reflective details for visibility in the dark. Shoppers preferring a looser cut should note the top is fitted with a slightly tapered waist.[1,2,3] | Boxy Fleece Jersey Sweatshirt: Choose this if you want a relaxed, boxy sweatshirt with a loose, cropped fit, dropped shoulders, and ribbed collar, cuffs, and hem. It is an I.FIV5-exclusive crewneck made of organic cotton-blend jersey (80% organic cotton, 20% polyester from recycled plastic) with a soft cotton fleece underside, offered in Grey, Navy/Midnight Blue, and Grape/Dark Crimson across sizes X-Small to X-Large. Note that the cropped hem sits at or just above the hips as worn, which may not suit those preferring a longer cut.[4,5] | Organic Cotton Fleece Jersey Hoodie: Choose this if you want a soft, plush fleece jersey layer for cool mornings, easy layering, or long hours of wear — reviewers describe warmth without bulk, a true-to-size cut with room to layer (one reviewer sized up to a Medium to wear it over another shirt), and a relaxed, cropped silhouette with a double-layer hood, drop shoulders, ribbed trims, and a kangaroo pocket. Note that the fleece may feel overly warm in mild climates or during high activity, and one buyer cancelled for that reason.[6,7,8,9] |
