Sea to Summit - 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 15 (EN rated -1.6°C). On sale now. Won't it be too tight? I have tried both a regular Spark 15 in the store, and a Spark Pro 15 (both in Long versions, as I'm 194 cm tall), and they are surprisingly roomy. I am a big guy at 116 kg, and I can roll onto my side inside the bag and throw my legs around. For comparison, I have tried getting into a Nordisk Passion Five XL bag too, and it wouldn't even close around my shoulders. I went with the Spark Pro 15 for the better down (so an extra degree of warmth) and additional features, but could as well been happy with the regular one. Already tested the bag out camping, and those features came in handy from flexibility standpoint - it was toasty with only 12C outside, so I opened it into a quilt and was very comfy all night. I'll be going to the Carpathians next week to sleep at 1500-1700 masl elevations and I think 3-7C degree temps, so I can share my experience afterwards, if you'll still be interested by then.

I haven't yet used them for the ventilation per se - I've just opened up the bag completely and turned it into a blanket. I guess it's kinda tedious to zip it all up in the dark once you open them all all the way, since you'd neet to put in the ends of all 3 zippers. The main zipper on both regular and pro Sparks is a piece of art - it's a №5 zipper for starters, so less biting to start with, then the slider is a weirdly flat looking non-biting one, and there is a semi rigid plank along the whole zipper. I haven't managed to make it bite into the fabric yet - not while testing and the one night out that I had with it. The additional zippers are regular #3, but they won't see as much use, so it's fine. As for the rating, Sea to Summit lists ISO Comfort for regular Spark 15 as -2C, and for the Spark Pro 15 as -3C (https://seatosummit.eu/products/spark-pro-down-sleeping-bag?srsltid=AfmBOopnuqGUSijF2ScQljEVj7z6zcynkJ1nxRCZnEX40v0atLc9kIrm#product-techspecs)

Sea to summit Spark Pro is awesome!

I wanted a bag to fit me for end of autumn beginning of spring and ordered a s2s spark pro -1C, cumulus xlite 400, cumulus panyam 450 and a WM megalite. I needed up choosing the WM for the sizing, im a bit bigger, 187cm 98kg, the zip is nice and the loft was c. 20 % more when laying the bags together.

I live in Greece and usually order from: [http://verticalextreme.de](http://verticalextreme.de) [http://bergfreunde.eu](http://bergfreunde.eu) [http://bike24.com](http://bike24.com) Decathlon is another option. Many of my friends prefer it as it offers some value for the money products. I haven't tried it personally. I would start with a good & lightweight sleeping pad & bag and of course a tent. Currently, I own a **Vaude Hogan SUL 1-2** tent **Vaude** **Performance 7** pad **Sea To Summit Spark Pro -1C** sleeping bag, which I bought a few days ago and looking forward to use in my next adventure.

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

Sea to summit spark or katabatic and buy their hood. I’ve tried both and prefer katabatic (quilt)

I have the Disco as my car camping sleeping bag. I have a Sea to Summit more ultralight down bag for backpacking. The Disco is warm and comfy, plenty of room, and I like the gills!
