Naturehike Egg-shaped Cotton Sleeping Bag (2026)

Experience cozy nights and unrestricted comfort with our PS Series Sleeping Bags With Arm Holes (PS300 / PS500). Designed for campers who value spacious freedom, warmth, and soft-touch materials, this sleeping bag is ideal for camping, road trips, casual lounging, and four-season outdoor relaxation. Its unique egg-shaped silhouette and arm-hole design make it perfect for both restful sleep and comfortable leisure time.

Key Features:

• Roomy Space and Free Movement
  The innovative egg-shaped structure creates a wide and open interior, allowing natural sleeping postures without tightness. The built-in arm holes let you stretch, relax, and move freely whether you are lying down, reading, or sitting up in camp. Enjoy a cozy, unrestrained experience from evening to morning.
• Double-layer Warmth with Offset Stitching
  Engineered with a dual-layer construction and offset quilted seams, the sleeping bag effectively reduces heat transfer between the inner and outer layers. This enhances overall warmth and stability, keeping you comfortable even when temperatures drop. The down-like rayon filling adds a fluffy and heat-retaining feel.
• Soft, Skin-friendly Materials
  Crafted with a gentle 300T poly pongee exterior and a silky peach-skin-like inner lining, the sleeping bag feels smooth and soothing against the skin. All materials pass formaldehyde safety testing and are designed for safe, comfortable use in close-contact sleep environments. The interior is extra soft, providing a pleasant touch throughout the night.
• Water-repellent Outer Layer
  The outer fabric features a water-repellent finish that helps dew and light moisture slide off with a simple shake. Whether you are camping in the mountains or relaxing under open skies, the surface keeps the inside drier and more comfortable.
• U-shaped Hood for Added Protection
  The U-shaped hood wraps gently around the head, helping reduce cold drafts during the night. Tightening the hood opening enhances insulation and creates a warm and secure sleeping environment in cooler conditions.
• Reliable for Outdoor Adventures and Indoor Leisure
  From tent camping to car camping or even relaxing at home, this sleeping bag offers excellent versatility, comfort, and protection. Its thoughtful design makes it a dependable companion for a wide range of outdoor and indoor moments.
