Zip Coupling

Down and synthetic bags identified with our zip coupling symbol use a 65 inch #5 YKK full-length zip which allows a unisex left-handed and women's specific right-handed bag to pair together.

Designed to pair side by side, each person sleeps in their own bag enabling each of you to take advantage of your bag's unique insulation zones, hood and footbox features - perfect for cozy adventures for two.

Bags with full-length #5 YKK zips on both sides can also be coupled together with other pairing bags.

    Thanks for your question!

    Unfortunately, the Spark and Flame series bags cannot be zipped together. We have put together a guide of all Sea to Summit sleeping bags (past and present) to indicate which ones can and cannot be zipped together – you can find this here https://seatosummitusa.com/blogs/ask-baz/can-i-zip-two-sea-to-summit-sleeping-bags-together
    Please let us know if we can provide more details

    Hello!
    After creating a list of many many sleeping bags available, your Spark3 and Flame3 sleeping bags came out on top. Now the question is: Is it possible to connect these two bags? I could not find a remark specifically denying it. And they do have a left (Spark) and right (Flame) zipper – and at least in the latest III model the zipper seems to go all the way to the footbox.

    BR, Daniel

    G’day Alexa. Sorry to say it’s not possible to zip two Journey Jo II sleeping bags together. The Journey (along with all of our women’s sleeping bags) has zippers on the right side of the bag, and there is no way to zip two right-side zippers together.

    Hello I have a question I own two journey II women sleeping bags and I’m curious is it possible to attach them together or not?

    Hej, Erik

    Thanks for reaching out to us. The Quest sleeping bags have only one zipper; it runs down the side of the bag and around the footbox. The Traverse (and Trek and Ascent) sleeping bags have both a side zipper (always the same length regardless of sleeping bag size) and a second sipper in the footbox. That side zipper can be coupled with the side zipper on the Venture, Journey, and Altitude sleeping bags. It isn’t possible to zip a Quest to any other sleeping bag.

    If you would like further details, our colleagues at the Swedish Sea to Summit distributor claims@cirdan.no will be happy to assist you further.

    Cheers

    The Sea to Summit team
