During a day on Kilimanjaro the temperatures can easily range from the high 20's (centigrade) right down at night to -15c. To cope with this huge range in temperature your clothing and kit strategy needs to be based around combining lots of thin layers that you build up and take off as the weather demands. Kilimanjaro National Park operates an absolutely strict limit of 15kg per porter for your main equipment bag, which includes your sleeping bag. This is more than sufficient for your needs on the mountain. Your bag will be weighed before you leave the hotel to start the climb and if it is overweight you will have to take items out and leave them at the hotel.
