Spark Pro

Yes, I used to use the Sea to Summit Spark Pro, but I found it didn’t work well for me since I’m a side sleeper — I’d often end up sliding off the pad. Quilts can be secured to the pad, which makes a big difference for someone like me. Also, I’m a 5'5" female, and most regular sleeping bags are way too long. Custom-made quilts are a much better fit.

Sea to summit Spark Pro is awesome!

Sea to Summit Spark, or therm a rest Hyperion. Both just a bit bigger then a nalgene bottle when it is packed down

Take a real hard look at the Sea to Summit Sparc rated to 30f, also comes in a 45 and 15. Beautiful bag, stuffs to the size of a 1ltr water bottle. Fabric and down technology is,in my humble opinion, unmatched. I’ve been in the industry for many decades, owned and tested more bags than I can name. S2S bags are a well kept secret.

Sea to Summit bags are excellent. Western Mountaineering makes bags that are a little higher quality than S2S, and more expensive. Feathered Friends is another excellent bag. Both of these brands are small American companies who focus on making the best products they can, price be damned. If you’re at all concerned with price the Sea to Summit Spark will work just fine. If the price doesn’t bother you, Western Mountaineering or Feathered Friends bags will keep you warm and happy for decades.
