This moisture-wicking fleece underwear set from Pioneer is the perfect midweight underlayer for a day on the ski slopes. Ideal for wearing under outerlayers, it also works as a comfortable set of pajamas on cold winter nights. With comfort seams and fly access for convenience, you'll want to pack this for your hiking treks and camping trips.

Why choose this underwear set?

• Moisture-wicking material prevents sweat from building up to keep you cool
• 2-way stretch fabric and comfort seams for freedom of movement
• Elastic ribbing on neck, wrist and ankle cuffs for a snug fit
• Fly access for ease of convenience
• Comes in a vented Pioneer stuff bag

Why not?

• Fleece is more prone to pilling than materials like wool
• Not recommended to be worn on its own in cold weather

Pro Tip:
Moisture wicking clothing is designed to pull sweat from the surface of your skin to the exterior of the fabric. This allows your sweat to quickly evaporate without soaking into your clothing.
