Extended Product Information
FAQs
What is the extreme temperature rating?
The bag has been tested down to -15C, though this is the extreme limit and not the recommended comfort range.
Can I wash this in a machine?
Hand washing is recommended to maintain the integrity of the hollow fibre insulation.
Is this sleeping bag waterproof?
The ripstop shell is durable and weather-resistant, but it is not waterproof; use a bivvy bag or tent ground sheet in wet conditions.
How do I connect it to another bag?
Use the two-way zipper to link the side zips of two compatible sleeping bags together.
Does this bag come with a compression bag?
Yes, it includes a convenient drawstring storage bag for transport.
What is the length of the bag?
This model is 200cm in length.
Troubleshooting
The zipper is getting stuck on the fabric
Gently pull the fabric away from the zipper track and ensure the storm flap is lying flat before zipping.
The bag does not feel warm enough
Ensure you are using an insulated sleeping mat beneath the bag, as ground cold can rapidly sap body heat through the compressed back insulation.
Storage sack is difficult to close
Roll the bag tightly from the bottom upward, squeezing out as much air as possible before sliding it into the sack.

Setup, Compatibility & Care
To maximize the performance of your Summit 250, always store it loosely in a large breathable bag rather than the provided compression sack during long-term storage to maintain the loft of the insulation. When packing for a trip, use the drawstring sack to compress the bag for easier transport.
To connect two bags, ensure both units have compatible zipper systems and zip them together on a flat surface before inserting your sleeping pads. For cleaning, hand wash the bag using a mild detergent specifically designed for synthetic sleeping bags, and ensure it is dried completely in a well-ventilated area away from direct heat sources to prevent damage to the shell and filling.
