Super soft and comfortable pants with a cozy fleece lining that keeps me warm in cold weather. They’re roomy enough to layer underneath, which is great for winter. Even with the fleece, they’re still breathable and easy to move around in. Only reason for 4 stars is that they could use a bit more insulation for really cold or snowy days. Overall, solid choice for casual cold-weather wear.

#teamnikeFuzzy sweat pant
Fuzzy pant - 10 Sept 2025
These are very comfortable and the fabric feels great. I don’t particularly like the fuzzy look on the pants. These are definitely different and make me think of something Jaden Smith would wear.

#teamnikePerfect for Warmer Weather
Stacy - 10 Sept 2025
My husband really loves that these pants are soft yet durable. The drawstring waist keeps the pants from falling down, which is a must! The weather isn't quite cool enough to wear these pants for working out or doing stuff in the yard, but he plans to wear them outside during the late fall / winter. The pants are extremely comfortable, so they'll also be a go-to apparel item for football Sundays. The navy blue color is great, and will go well with most shirts. The pants definitely run big, so I'd definitely recommend ordering a size down from your usual size. The pant legs are really wide, so even if my husband had sized down -- the style itself isn't quite what he was looking for.
