Use the chart below to determine your size. If you’re between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If your measurements for chest and waist correspond to two different sizes, order the size indicated by your chest measurement for tops and your hip measurement for pants.
Our three different fits - slim, regular, and relaxed - ensure that when worn together, layers move and breathe like a single garment.
A snug, close-to-body fit for low bulk layering.
Neither snug nor loose - garments that are worn solo or over other layers.
Loose fitting lightweight layers.
A soft and stretchy women’s T-shirt with an updated fit and fabric that makes it even more comfortable, the Siren Long Sleeve Sweetheart Arena is made with our 150gm jersey corespun fabric. Corespun uses merino wool fibers wrapped around a nylon core for added strength and durability, which retains next-to-skin softness. We've added a touch of LYCRA® to provide just enough stretch to withstand holding shape throughout your day. Icebreaker's Arena sheep print humbly reminds us of our unique heritage, and the sheep that keep us cozy. Ideal for year-round use whether traveling, hiking, or relaxing after a big day outside, the Siren Long Sleeve Sweetheart also features a feminine neckline and a slim, flattering fit that’s perfect for everyday comfort and layering.
