Sea To Summit Spark SpIII Sleeping Bag Review

[@maren5902]

Awesome demonstration and explanation, thanks a lot!

[@nathandolenc554]

I love my Spark 3 (Long version). It's super lightweight and very lofty.

[@maximusnukeage]

The fact that you can put two bags together for a couple is a cool feature

[@thegoodridesnow]

We thought so too!

[@FancyTowel]

It's interesting that it works, since the website states "NOTE: This bag is not designed to pair with another"..

[@thegoodridesnow]

The Spark and Flame models of sleeping bags are compatible to zip together. But they are not designed to zip to the other models of bags. The info is at the bottom of the product page under the FAQ’s. Their other models of sleeping bags are compatible to zip to each other as well. But they are not interchangeable between models.

@@thegoodridesnow Thanks for the response and the extremely helpful video! 👍

@@thegoodridesnow the information about joining is weird: seatosummit americas site says joining spark and flame is ok (as you demonstrated), but their european and australian sites claim joining is not possible. Left an inquiry to the european site what's the deal here. update: the customer service responded: the are two versions still on sale. Older one with zipper sewn in at the end, updated version with open end. Only latter can be joined.

love the video. would you say this is okay for a side sleeper? 5'9" 165lb dude so not a big guy.

[@thegoodridesnow]

Hello, I’m a side sleeper and didn’t have any problems. If you are looking for a bit more room, you could always size up one size if needed.

@@thegoodridesnow thanking for getting back to me! i will likely go with the regular 18 degree bag. thanks!

[@thegoodridesnow]

No, this particular bag goes down to 5F
