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.

Look at the Cumulus X-Lite 300 or 400 in XL length - at 195cm you are on the cusp of the large length, but too close, in my opinion. I have a medium length which is spec'd to 183cm (I'm 173cm) and I would recommend that anyone at 179cm or above should size up to ensure proper hood coverage. Note: the standard 3mm, 2/3rds zip is prone to snagging and potentially tearing the 7D shell fabric, so a slow and patient hand is needed. Some upgrade to a 5mm zip, which has a backing that reduces this issue. WM and Feathered Friends are top notch, but Cumulus is a close second. Cumulus beats both on weight, primarily by using lighter fabrics/zippers. Here in the US, Cumulus Bags are $150-$200 cheaper than a comparable bag from WM or FF.

For the sleeping bag I’d recommend a zpacks, timmermade or cumulus 30f range sleeping bag you could push into much colder temps wearing alpha 120 bottoms, down jacket, and down foot booties inside the sleeping bag. I’ve used this combo of clothing to push my 12oz 50f sleeping quilt down to 20f comfortably. If you plan to camp mostly in the summer I’d get the 50f bag and just wear more clothes inside it to push temps lower in fall. I switched to this technique and was able to reduce my pack size a lot and half the weight of my sleeping bag and its bulk. It works well since I’m already taking the alpha pants and down jacket anyways so I might as well wear them and save weight on the sleeping bag. The wind makes the biggest difference to me for how much insulation I need at night. For High Wind below freezing a windproof bivy that can fit over your pad and quilt makes a huge difference to your overall warmth and stoping drafts. Many UL quilts with 7D fabric are not very windproof and even a 20f bag can feel very cold at 20f in high winds. I like to summit camp and it’s often very windy above 6000ft. For the sleeping pad I’d recommend the thermarest nxt https://cascadedesigns.com/products/neoair-xlite-nxt-sleeping-pad?srsltid=AfmBOop1YJvl8n8oPU1vCNvveJ5sopEYhuUIcb1ORgJmz5-Sc-vxRd-W If 6.1 and the wide thermarest fits me but is still small. It packs down very small and is the most comfortable and insulated pad for the weight that I’ve tried yet. I have slept at 10f in the snow and been fine with it. You can also pair it with a gossamer gear thin light foam pad and gain more R values for freezing temps.

Take a look at cumulus bags. They can do custom fill (up or down, “waterproof” different fabrics etc ) and custom sizing for it as well if you wish. Not cheap but personally I think they’re the best down bags on the market.
