Product description

The Treeline TII down sleeping bag from Sea to Summit is practical and versatile. It is ideal for camping and adventuring in the summertime. The tough nylon outer shell compresses extremely well, so the sleeping bag packs down nice and small for easy transport. The down fill has been treated with a water repellent, so morning dew or condensation on the interior won’t cause it to lose its insulation properties. The mummy shape is spacious but still very thermally efficient. This is complemented perfectly by the draught collar and hood, which comes complete with a drawstring. As for storage, there’s an inside pocket you can use to keep a battery warm or store valuables. The 2-way YKK zip makes it easy to get in and out of the bag and allows you to regulate airflow as well. Another plus: the outer shell has a neat finish and is free of any loose fabric. If you don't want to sleep alone, you can combine it with other sleeping bags. A practical option for summer adventures in your tent, campervan or the open air.
