The PrimeFlame Hooded Sleeping Bag by Wanderer has been developed with a temperature comfort rating of +3°C for use in warmer temperate climates or transitional seasons! Premium insulation provides maximum thermal performance, whilst the comfortable, soft touch, 190T brushed poly pongee lining ensures ideal comfort for the ultimate nights sleep! A high tech 300T soft touch ripstop polyester shell ensures durability for use night after night, and the heavy duty YKK zips with easy grab puller and full anti-snag zipper protection ensure you can get in and out with ease. The PrimeFlame has been designed with a tapered shape and contoured hood for comfort and the choice of either a left or right zip! Don't know which zip side to choose? As you're lying on your back, a left zip bag will have the zipper on your left, and the right zip bag will have the zipper on your right. Generally, campers and hikers find it easier to reach across the body with the dominant hand to use the zipper - So, right handers would choose a left zip bag, and left handers would choose a right zip bag. However, if you like to sleep on your side for most of the night, you may like the zip to be in front of you for ease of exit, so you would choose a bag with the zipper on the side of which you usually sleep!
