The Prologic Avenger Sleep System takes the Avenger 6 and 8 leg bedchairs and pairs them with the new 3 Season Avenger sleeping bags. The sleeping bag is attached with a continuous, oversized heavy-duty zipper, creating a secure connection that can be removed easily for cleaning. The thermal fleece lining, hollowfibre and multi-layered construction aim to provide comfort, insulation and functionality. The system is covered in ultra-soft, anti-rustle and hardwearing waterproof polyester. Two heavy-duty crash zips allow efficient entry and exit, and each is fitted with anti-open clip-locks to keep the opposing zipper closed and prevent drafts. Wind baffles further reduce drafts for a comfortable night's sleep.
