As you plan your trip to Kilimanjaro, the biggest thing you have to pay attention apart from safety and preventing death on Kilimanjaro is what to pack. While you are arranging all the things you plan on wearing on your Kilimanjaro climb like hiking boots and rain protection, don’t forget about planning what to wear when you sleep, including your sleeping bag. The most important function of your sleeping bag on Kilimanjaro is to keep you warm overnight in freezing temperatures. So the best sleeping bag is one that is rated for very low freezing temperatures. Most tour operators will provide you with the most suitable sleeping bag to rent during your Kilimanjaro climb, but be sure to ask in advance and prepare for the coldest temperatures.
How warm should your Kilimanjaro sleeping bag be?
However, given you are reading this, you probably have never had a need for such a high-performance sleeping bag, nor will you have so in future. Under normal circumstances, you would prefer your sleeping bag to be lighter and less bulky. Thus, it would be a real waste to buy a new sleeping bag just for one-time use on Kilimanjaro. Therefore, most people prefer to simply rent a sleeping bag from their operator.
In our group of 12 hikers, 11 had come to that conclusion and rented the Mountain Hardwear Lamina Z Bonfire 30 Sleeping Bag from our operator. The only hiker who brought his own sleeping bag (also rated for minus degrees, yet not up to -30°) ended up cold overnight and regretted his decision not to rent in hindsight.
Best to rent your sleeping bag for Kilimanjaro from a high-quality operator
Beware of low-quality sleeping bags on Kilimanjaro climbs
However, beware! Not all operators offer high-quality equipment. In fact, most don’t. If in doubt, better check with them to confirm exactly the type of sleeping bag they would provide. Other than the model, also confirm their usage practices. It doesn’t help if they provide the best of all models but then use it over and over again. After about 10x washing, sleeping bags lose their functionality and will no longer keep you as warm as they should. Read more about operator selection criteria on this blog, and about the shockingly poor sleeping bag practices of budget operators in my book.
Sleep without socks in your sleeping bag on Kilimanjaro
Finally, a counter-intuitive piece of advice: Sleep without socks to avoid getting cold feet! Yes, I know, that doesn’t sound right. I resisted for several nights, experimenting with air activated feet warmers, or self-heating badges, and two pairs of thick thermal socks instead. Nothing worked; my feet felt like ice every single night. Finally, I followed my guide’s advice to sleep bare feet, and—lo and behold—my feet felt warm and cozy all night long!
Wishing you a great experience climbing Kilimanjaro!
I strongly believe that a Thermos should be on everyone’s kit list. From hot water warming your body when it’s really cold to a steaming hot towel in the morning, I promise you will love it. It’s absolutely worth the extra weight. Read more about all its fantastic uses on Kilimanjaro 
In our age of gadget addiction, solar panels have become unbelievably popular on Kilimanjaro. They are definitely worth the money if you plan to use your phone a lot, as I did to write my book! My panels worked like a charm and I absolutely loved them. However, they are a total overkill under normal circumstances. If just to take photos on your phone, you might want to invest the money into a decent camera instead. For most people, solar panels will end up in their cellars and never be used again. What a waste just for one trip!
Freezing overnight in my tent and during summit night was my biggest fear about Kilimanjaro. Of course I made sure to bring a stack of self-heating badges, i.e. air activated warmers that supposedly heat up as soon as you have opened the packaging and stay warm for several hours thereafter. I brought special hand warmers to put inside my gloves, toe warmers to stick to my socks, and even big warmers for my back. Conclusion: All of them were totally unreliable and – as a result – completely useless. The few instances they worked, they were far too hot. And when I most needed them, i.e. during summit night when I could no longer feel my fingers and toes, they didn’t work at all! I highly recommend you to invest in proper gear instead, like warm 
This is for women only. Surely you must have wondered how you will be able to pee in privacy. Blogs warn that at higher altitudes there might be nowhere to hide behind. Marketeers have jumped on this opportunity and come up with FUDs, short for Female Urination Devices. They promise the impossible: pee while standing, just like men. Theoretically, sounds great. Practically, I haven’t seen a single woman using them, nor was there any need to do so. Other than close to the summit, we always found rocks to hide behind; and even summit day won’t cause you any problems because you won’t drink much during summit night in any case. More about that 
in terms of functionality, just select a good price option. And no need to pay extra for touchscreen compatible index fingers – the material will get scratched from holding onto rocks and turn this feature useless in no time.
