Cumulus - X-Lite 400

Had the same question on my mind, I focussed even on the same brands! I also use my bag in central europe, sometimes in higher elevations: After my - exhausting and nerdy - research I can attest you, that some customers complained about the lack of warmth of the WM summerlite. And its not the manufacturers faulft, (WMs temperature rating are trustworthy!!!) but you can have some colder than expected nights on high(er) elevation. Also sometimes you are lacking the calorie intake before you go to bed, so your body depends on a toasty warm bag. Also exhaustion can add to the equation. So if you can‘t get the overfill on the summerlite, I‘d rather go with the xlite 400, or just look into warmer bags. Last week me and 2 friends did a thruhike in Madeira, East to West with a lot of elevation change. My WM Bag is rated for -4 degree. Turns out it was perfectly fine for the subtropical climate, because we had 1-2 nights at around 0. If its too warm, you can either open the bag or with WM bags, you can shift the down from top to bottom tonregulate the warmth. Brilliant feature. Another food for thought: Don‘t get yourself talked into buying a quilt, if thats not your thing. A wide cut and light seeping bag is the cosiest thing you can have! At one night last week, my friends 9 degree bag was dangerously too cold, so i unzipped my bag (mine can be transformed to a blanket) and put it on top of us both. You feel EVERY draft at your shoulder, your knee, your feet, whenever this thing raises. You feel the shivering going up from the exposed body part (maybe its then cold blood pumping along your vessels). @NewChipmunk2174 I believe quilts have their place at above 6+ degrees or so. Everything else is (personal opinion) just geeky and cumbersome and at worst just drafty and cold as hell. Just look how many Quilt products are out there, who are packed with „features“ (need for balaclava, elastic straps, bottoms without insulation, clips, sinches, bedhsheets, „you can wear your Downpuffy anyways“, zippers,….) so that they are again on the brink of being called a standard sleeping bag. Going full circle… Thats no rent btw! I wanna get one for summernights with 9+ degrees :-)

I got the Cumulus X-Lite with 440 grams of down. The day after I got it, I spent 2 weeks hiking in the Drakensberg. We had 4 nights below zero, and the last day we woke up under the snow. I was not cold once. The sleeping bag gets so big when you let it out of its compression bag, it's amazing. The quality is top notch. [Picture](https://imgur.com/3M6SsR4)

A water repellent outer shell also means it will dry up less easily if it does get wet. From my experience, it's not necessary at all. I don't know what you're planning in Kyrgyzstan, but I was more than fine with the Cumulus X-Lite 400 + down jacket.

I have a custom Cumulus similar to what you’re describing. Never was cold even on the Kungsleden (even slept unzipped with snow outside). For me it’s not tight (female) but since it’s custom you could ask to make it wider. I also got the outer material that repels water (can’t remember the name rn) and it works really well for condensation. All in all Cumulus is a great brand imo. 

Hey so I just checked and this was the order: Your order: based on X-lite 400 outer fabric: Pertex Quantum Pro 36g Chestnut inner: Toray black zipper 2/3 5mm left side zip 500g of non-hyrophobic down with footbox overfill

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.

Pretty sure that bag will be overkill, plus it's heavy as hell. Look at Cumulus Bags - $19 shipping to US, last I checked. I have the X-Light 400. I sleep cold, and this bag is too warm to use zipped up above 35F. The heavier, budget equivalent would be the Panyam 450. The Panyam 600 is closer in warmth to the Bishop Pass, but it would still be overkill. You can add extra down to the Panyam 450 or X-Lite 400 to boost warmth for extra $$$. https://cumulus.equipment/us_en/sleeping-bags/down.html

Cumulus X-Lite 400. Comes with a 5L stuff sack. $154 cheaper than the Hummingbird UL 30 (no tax, +$19 shipping to the US), more down (warmer), packs smaller. I've found the 400 to be too warm above 40F, so I have a 300 on order.

For sleeping bags, the Cumulus X-Lite series is probably the best bang-for-the buck, price and weight-wise, if you are able to use the standard default size. Custom sizes quickly raise the price. Additional overstuff is fairly inexpensive.

I have a cumulus x-lite and really love it

Only 200. Bought it as an UL d sleeping bag for emergencies during overnight bike rides, but I’ve actually used for summer camping too.
