Ultra Light Sleeping Bag

For the serious hikers / backpackers looking to save precious weight.

If you love hiking but are always looking for ways to keep your pack weight down then check out our list of ultra light sleeping bags.

Down filling (bird feathers, I suppose that’s why they can fly) tends to be the lightest but is not suited to getting wet.

Ultra Light Sleeping Bag

Ultra light sleeping bags tend to be very expensive due to down fill and materials being used. But spending more on a good quality sleeping bag that will last you 10 plus years if looked after, is well worth it by reducing your carry weight and keeping you cozy warm at night. Also keep a lookout for store sales, as you can save almost 50% if you shop around and aren’t in a hurry.

Remember your safety is paramount, if you are planning on hiking where the weather can get below freezing make sure to have the right equipment even if it weighs a bit more, don’t skimp 10 extra ounces on your sleeping bag but risk your safety.

To be called ultra light the weight range we found was between 1 to 2 pounds (450 to 900 grams), although we have listed one here that weight 2 lb 8 oz (1.13 kg) purely because it’s so much cheaper than the rest.

Any way here’s the list of ultra light sleeping bags we found, hopefully there is something here to fit your budget and trip:

We recently purchased the Vango Ultralite 200, it cost us around $100, and weighs in at a very light weight 32oz (900 gram). The extreme temp. rating is 12F (-11C) and comfort rating of 39F (4c), I wasn't overly warm the couple of nights we used it on the coast (about 39F I think) but for the price and weight I personally thinks it's a very good buy. We'll be using later in the year in the mountains so will update again.

Make sure to double check our ratings and weights to make sure the sleeping bag you buy suits the type of hiking or backpacking you’re planning.
