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.
