X-Lite 400

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 had a similar discussion with myself and compared a few from s2s, cumulus and wm. ended up with a WM Megalite, if it wasn’t for the fact I needed to customize I would have probably chosen the xlite 400, with added width and a 5mm zip.

I had three of those bags in my house at the same time along with a panyam 450. The s2s was the -1 version. I was disappointed with my quilt for shoulder season temps so decided I wanted a bag. Comparing the loft side by side the WM was the winner and I liked the extra width being a bit bigger. If you are ok with the standard size of the xlite and the standard 3mm zip the xlite is a great buy. Ps as you eluded too the Sea to summit ratings are T lower limit ratings, the comfort rating of their -1C bag is 4C, the comfort of the -9 is -2C, #marketing

No idea sorry. The xlite has a 3mm zip which I didn’t get on with but some are ok using it. You have to be gentle not to snag.

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 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.

Cumulus x-lite is a great bag that is INSANELY packable. Worth the money, especially since you can customize a lot of options to fit your needs.

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.
