Sea to Summit Traverse II

The Traverse II uses Thermolite synthetic insulation, which is specifically designed to retain its loft and thermal properties even when damp. This makes it a reliable choice for humid environments or unpredictable weather where down might lose its effectiveness.

Yes, the bag features a wider mummy cut that offers more room to move than traditional, restrictive mummy bags. It is designed to accommodate those who shift positions throughout the night without sacrificing the heat retention of a mummy shape.

Yes, the Traverse II is designed to integrate with other compatible Sea to Summit sleeping bags. This allows you to zip two bags together to create a double sleeping system for shared warmth.

The bag features full-length side and foot box zippers, giving you excellent control over ventilation. You can unzip the foot box to cool your feet or open the entire bag flat to use it as a comforter on warmer nights.

The Traverse II is designed to fit users up to 78 inches (6 feet 6 inches) tall. If you are near this height, the bag offers a comfortable fit without feeling cramped.
