Operating Instructions
The Rime Light In Flex Vest is designed to provide insulation and comfort during outdoor activities. Its primary function is to offer warmth when temperatures drop and can be easily stowed away when not needed.
- Layering: This vest is ideal as a mid-layer or outer layer depending on the weather conditions. For colder conditions, wear it over a base layer and under a shell jacket. For milder, cool conditions, it can be worn as an outer layer.
- Stowability: The vest can be conveniently packed into its own left front pocket. To do this, turn the pocket inside out and begin stuffing the vest into it, then zip it closed. This feature makes it highly portable and easy to carry in a backpack.
- Mobility: The elastic material ensures freedom of movement, making it suitable for activities requiring dynamic motion such as hiking, climbing, or trekking.

Maintenance and Care

- Drying: Tumble dry low or hang dry. Ensure the vest is completely dry before storing to prevent mildew.

Troubleshooting
This section addresses common concerns you might encounter with your vest.
- Reduced Warmth:
- Cause: Insulation may be compressed or wet.
- Solution: Ensure the vest is clean and dry. If wet, dry thoroughly as per care instructions. Avoid over-compressing during storage.
- Zipper Sticking:
- Cause: Dirt, debris, or fabric caught in the zipper.
- Solution: Gently clear any obstructions. If the zipper is stiff, apply a small amount of zipper lubricant or a graphite pencil to the teeth.
- Water Repellency Decreased:
- Cause: The Durable Water Repellent (DWR) coating may have worn off.
- Solution: After washing, tumble dry on low heat to reactivate the DWR. If this doesn't work, consider applying a DWR-restoring product specifically designed for technical outerwear.
