The Layering System (Weather)
Mastering Weather
Mornings on the river in May will frequently be in the low 30s with frost on the boat seats. By 2:00 PM, if the sun comes out, it could be a beautiful 65 degrees. You MUST dress in layers.
- Base Layer: High-quality merino wool top and bottom.
- Mid Layer: A thick fleece or synthetic puffy jacket.
- Outer Shell: 100% waterproof and windproof Gore-Tex jacket and bibs (or waders).
Do not bring cotton hoodies or jeans. If they get wet, you will be miserable.
