Simms Strata 160 Base Layer Bottoms - Grey

Their primary purpose is to serve as a first layer, providing insulation and managing moisture to keep you warm and dry during outdoor activities in cool to cold weather.

These are designed as a base layer and are not intended for standalone wear in casual or public settings. They function best when worn under other clothing like waders or ski pants.

Refer to the sizing chart provided by Simms. The base layers should fit snugly against your skin without being constricting to ensure optimal performance for insulation and moisture-wicking.

The blend is designed for temperature regulation. While providing warmth, the polyester content and the fabric's breathability help to wick moisture and prevent overheating during active use.

Yes, they are an excellent base layer for cold weather. For extreme cold, they should be paired with appropriate mid and outer layers for maximum insulation.

Machine wash cold on a gentle cycle with mild detergent. Avoid bleach and tumble dry on low heat or air dry. Do not iron or dry clean.

This product description does not specify the presence of a fly or zipper. Typically, base layer bottoms are designed without them for a smooth, comfortable fit under other garments.

Ensure you have selected the correct size. The 4-way stretch is designed for a snug fit, but if it feels overly tight, consider sizing up. Ensure they are worn as a base layer and not too many layers are constricting movement.

Check that you are not using fabric softener, as it can clog the fabric's wicking pores. Ensure the garment is clean and free of body oils or dirt that could impede performance. Wash with a technical fabric cleaner if necessary.

While designed for comfort, some individuals may be sensitive to seams. Ensure the garment is positioned correctly on your body. If persistent, consider using a different base layer with flatlock seams.
