Trail Lite Sleeping Bag: 35F Down

DWR, or Durable Water Repellent, is a treatment applied to the fabric of your sleeping bag that makes it water-resistant. This means that water will bead up and roll off instead of soaking in, keeping the insulation dry and effective. This is crucial for outdoor activities, as it helps ensure you stay warm and comfortable even in wet conditions.

Fill power measures the loft or fluffiness of down insulation. A higher fill power, like 600, indicates that the down is lightweight yet provides excellent warmth. This means your sleeping bag will keep you warm without adding unnecessary weight, making it ideal for backpacking and camping trips.

A mummy design is shaped like a cocoon, tapering at the feet and wider at the shoulders. This design minimizes the space inside the bag, reducing heat loss and making it lighter and more compact. It fits snugly around your body, providing enhanced warmth and comfort, especially in colder conditions.

Trapezoidal side baffles are compartments within the sleeping bag that hold insulation in place. Their unique shape helps keep the insulation evenly distributed, preventing cold spots where heat can escape. This design enhances the overall warmth and loft of the sleeping bag, ensuring you stay cozy throughout the night.

Synthetic fill is made from man-made materials that provide excellent insulation. Unlike down, synthetic fill retains warmth even when wet, making it a reliable choice for outdoor gear. Using synthetic fill in the footbox of your sleeping bag ensures that you stay warm and comfortable, even in damp conditions.

Absolutely! Sleeping bags with synthetic fill are designed to perform well in wet conditions. Unlike down, which loses its insulating properties when wet, synthetic materials retain warmth and dry quickly. This makes them an excellent choice for camping or backpacking in unpredictable weather.
