A cluster of common questions shows up around fleece as a fabric: is it actually warm, does it make you sweat, how is it different from a sweatpant, and what does "fleece lined" mean versus a plain fleece sweatpant. This is a quick, straight-answer FAQ for anyone selling fleece sweatpants and hoodies who wants to answer customer questions accurately.

Is Fleece Actually Warm?

Yes. Fleece is a brushed fabric construction that traps air between its fibers, which is what gives it insulating warmth without a lot of added weight. It is meaningfully warmer than a plain cotton jersey tee fabric, which is why fleece is the standard choice for sweatpants, joggers, hoodies, and crewnecks rather than tees and tanks.

Does Fleece Make You Sweat?

During light activity or everyday wear, fleece is comfortable and breathable enough for most people. During higher-intensity exercise, the same insulating property that makes fleece warm also traps heat against the body, which can lead to sweating faster than a lighter performance fabric would. This is part of why fleece sweatpants and hoodies fit post-workout, warmup, and lounge use better than they fit an actual training session. For active training wear, a performance moisture-wicking fabric like the Sport-Tek pieces in the catalog is the better fit.

Fleece vs Sweatpants: Not Actually Two Different Things

"Fleece" and "sweatpants" get searched as if they are competing categories, but they describe two different layers of the same product. Fleece is the fabric. Sweatpants is the garment. A fleece sweatpant is simply a pair of sweatpants made from fleece fabric, which describes essentially every sweatpant and jogger in the Bear Grips catalog. See the joggers vs sweatpants comparison for the actual style differences within the category.

What Does "Fleece Lined" Mean?

"Fleece lined" typically refers to a garment with an outer shell fabric (often a wind or water-resistant material) and a separate fleece layer sewn in as the interior lining, common in outdoor or winter-specific pants. This is different from a straight fleece sweatpant, where the entire garment, inside and out, is fleece. The catalog does not carry a separate shell-plus-lining winter pant. Every bottom in the fleece category is a straight fleece construction throughout.
