SEA TO SUMMIT Comfort Blend Sleeping Bag Liner Rectangular with Pillow Sleeve Sleeping bag liner
ASL032071-250201 How to choose the right sizeThe Comfort Blend Liner from Sea To Summit is a sleeping bag liner that is suitable for all travellers as hygienic protection when sleeping in mountain huts and hostels. It is made of lightweight polyester and natural Tencel fibre, which makes it feel like a classic bed linen. In hot weather you can use it instead of a sleeping bag, for example when sleeping in a hammock. It is partly made using recycled resources.
For a really comfortable sleep, we recommend to complete the sleeping bag not only with a liner but also with a functional thermal blanket.

Zipping two compatible sleeping bags together creates a warm, cosy and comfortable sleeping space for two people. It’s a much more flexible option than a double sleeping bag (which explains why there are so few double sleeping bags on the market).
However, NOT ALL sleeping bags can be zipped together. Below you’ll find a table listing the Sea to Summit sleeping bags that can be joined – at the bottom there are notes clarifying which side zip is listed in the table (and they also include a warning about joining sleeping bags from brands other than Sea to Summit with Sea to Summit sleeping bags).

Note – the table above lists the main side zip. Some sleeping bags also have a zip in the footbox, others have a second short side zip. To join two sleeping bags, the main side zip is always used.
For sleeping bags to be compatible, both must have a full zip. Sleeping bags with a wrap-around or half zip cannot be joined to other sleeping bags.
The zip descriptions apply to Sea to Summit sleeping bags. A sleeping bag from another brand can be joined to a Sea to Summit sleeping bag if it has the same zip size and the teeth are oriented the same way inwards. If in doubt when joining two bags, do not force the zip slider – it could damage the zip slider or the zip.
