We hope that this guide will help you choose the best one for you.

We've looked at large 3 season sleeping bags and want to let you know about both the pros and cons. 3 season sleeping bags have enough insulation for colder weather camping trips in spring through to autumn, which ensures your body heat stays inside, so you can sleep soundly on even the coldest nights. Suitable for most conditions, except for when there may be frost or snow on the ground, they are extremely practical and will provide you with the insulation you need, unless you're planning on going on an alpine winter expedition. They are made from thicker materials than smaller and shorter sleeping bags, so they are very comfy and cozy to sleep in. These sleeping bags are very spacious for taller campers and those that prefer a bit of extra shoulder and leg room.
