When heading out for your next expedition, ensure your bag offers a high level of insulation, guaranteed to retain the body’s heat, keeping you toasty warm.

Sleeping Bag FAQs

How many layers should you wear in a sleeping bag?

Make sure you dress smart for a sleeping bag, as you want to ensure you stay warm without overheating. Though it depends on the temperature, generally for cold climates, make sure you wear one or two mid base layers that are highly breathable to allow your body’s heat to disperse throughout the bag. However, if you find you get too hot, you can also unzip the sides of the sleeping bag for it to act as a quilt or blanket instead.

Can you sleep in just a sleeping bag?

Again, it depends on the weather; however, in colder climates, it’s recommended you bring a blanket, a sleeping bag liner or a quilt to throw over your sleeping bag as well. Though most sleeping bags offer great warmth, if you’re looking for additional insulation, make sure you bring a few extra layers too.

What temp rating sleeping bag should I get?

This all depends on the weather conditions of where and where you decide to camp. Generally speaking, you’ll want to get your hands on at least a 10° bag or, most likely, a 0° or lower bag. The lowest temperature is designed to keep you warmer, so make you assess the temperature rating before purchasing. Also, if you become too overheated, look for something with dual side zippers so that the sleeping can act as a blanket.
