The Sea to Summit Hamelin Synthetic 30°F/-1°C Regular Sleeping Bag is a high-performance, three-season sleeping bag designed for damp environments. It combines technical trail performance with eco-friendly materials and optimal comfort for side-sleepers. Typically available in Picante Red, this sleeping bag is a versatile choice for outdoor enthusiasts.

Unique Performance Highlights

• Free-Flow Zipper System:
  Equipped with a full-length, two-way YKK #5 main zipper that wraps through the footbox, allowing the bag to be laid completely flat as a camp quilt. A secondary half-length zipper on the opposite side offers arms-free functionality, making it easy to read or prepare coffee without leaving the bag.
• Contour Relaxed-Mummy Shape:
  Designed with a more generous profile than traditional mummy bags, this shape provides extra wiggle room at the shoulders and hips. Perfect for side-sleepers or restless campers.
• Wet-Weather Resilience:
  Insulated with reVIVE Loft, a 100% post-consumer recycled multi-denier synthetic fill. Unlike traditional down, this material maintains its structure, insulates effectively, and dries quickly even in damp conditions.
• Eco-Conscious Build:
  Features bluesign-APPROVED 20D recycled polyester shell and liner fabrics treated with a non-PFAS water-repellent (DWR) finish. Additionally, the bag is part of Sea to Summit’s 1% for the Planet commitment.
