Used once for backcountry skiing after purchase. I haven't worn it since then. The Octa fleece is clean and has no pilling. It has a shell on the chest that can hold a cell phone and prevent battery drain in cold places. The sleeves have thumb loops, which are very helpful when taking off and putting on outerwear.

It features a hood and a long half-zip design that extends to around the solar plexus. The long half-zip makes it easy to put on and take off, and it functions as ventilation during activity, like OMM products, allowing for fine temperature adjustments depending on the activity load. You can keep it on almost continuously during activity. The hood has a relaxed silhouette with a three-panel, three-dimensional cut. The zipper can be raised to cover the chin, effectively blocking cold air from the neck while allowing for easy head movement.
