The Arc'teryx Rho LT Zip Neck is a warm, durable synthetic base layer with a cozy fleece interior that excels for cold-weather layering and a range of activities from camping to trail running and ski touring. It layers easily, includes handy pockets, and is built for longevity, though it is not the most breathable and has a boxy updated fit.
Patagonia’s classic base layer, heavier than Thermal Weight at 147-gram 100% polyester. It’s not as versatile as the Thermal Weight and can feel outdated for some, but remains a durable option for traditional layering.
The Maipo Low Impact Adjustable sports bra is ultra-soft and breathable, ideal for yoga and other low‑impact activities. It features highly adjustable straps, removable pads, odor control, and quick-drying fabric for a lightweight, comfortable fit, but it’s not suited for high-impact workouts or running and may offer limited support for larger chests.
