What is the Sea to Summit Hamelin -1C/30F Long Recycled Synthetic Sleeping Bag?
The Sea to Summit Hamelin -1C Long Sleeping Bag is a lightweight and roomy alternative to traditional mummy bags. It's designed for camping in various weather conditions and has a relaxed mummy fit that gives you extra space to move, making it perfect for side sleepers or those who feel confined in standard bags. It provides warmth, comfort, and versatility, whether on a damp coastal trek or camping under clear skies in cool temperatures.
What is it made of?
Insulation:The Sea to Summit Hamelin sleeping bag features REVIVE Loft insulation, which is designed to be extremely soft and comfortable against the skin. The insulation is also highly compressible, allowing the sleeping bag to be packed down small for easy transport.
Despite being lightweight and compact, the insulation maintains its loft, meaning it retains its ability to trap air, which is crucial for keeping you warm, even in damp conditions.
The insulation is also Bluesign-approved, which guarantees that it meets rigorous environmental, health, and safety standards. This certification ensures that the entire production process—from raw material to finished product—adheres to responsible practices, giving users the peace of mind that their sleeping bag is both high-performing and eco-conscious.
Shell and Lining:The shell and lining are both made of 20D recycled polyester. These materials are lightweight and durable, and they are also Bluesign-approved, ensuring they meet environmental and safety standards by minimising harmful chemicals in their production.
To enhance the sleeping bag's performance, the shell is treated with a PFC-free Durable Water Repellent (DWR) finish, providing water resistance without the use of perfluorocarbons (PFCs). PFCs are often used in waterproofing treatments, but they can persist in the environment and pose risks to wildlife and human health. By opting for a PFC-free solution, the Hamelin sleeping bag offers reliable protection from moisture while reducing its environmental and health impacts.
Additionally, the sleeping bag's fabrics are RCS-certified (Recycled Content Standard), verifying that they are made from post-consumer recycled materials. This certification ensures transparency and accountability in the recycling process, guaranteeing that the polyester used in sleeping bags comes from recycled sources like plastic bottles and other discarded items. By using RCS-certified materials, Sea to Summit is actively contributing to reducing the demand for virgin resources, decreasing waste, and promoting the reuse of materials that would otherwise end up in landfills.
What are its features?
The Sea to Summit Hamelin Sleeping Bag is designed to combine comfort, ventilation, and practicality for a great night's sleep in the outdoors. The relaxed mummy fit provides more space around the torso and legs than traditional mummy bags, allowing you to move without feeling constricted. This extra room enables shift positions during the night without compressing the insulation, which is crucial for maintaining warmth, as compressed insulation can lose its heat-trapping properties.
This sleeping bag has a Free Flow zipper system, which includes a full-length side zipper that continues through the foot box and a half-length zipper on the opposite side. This dual-zipper setup gives you multiple ventilation options, allowing you to unzip the bag entirely for airflow or even transform it into a quilt during warmer nights.
The #5 side zipper, equipped with double sliders and a zipper plough, ensures smooth operation without snagging, letting you make quick adjustments. On cooler nights, you can zip up fully to trap heat, while the anatomically shaped foot box is designed to prevent cold spots around your feet, ensuring they stay warm and cosy.
To further enhance warmth, the bag is equipped with a front draft collar and a draft tube along the zipper, both of which act as barriers to block out cold air. These features help prevent heat loss through the zipper area, keeping the bag's interior well-insulated and comfortable.
The hood is designed to fit a regular Sea to Summit Aeros pillow. This integration gives you the added comfort of securely placing your pillow to enjoy a good night's sleep that feels just as cosy as home, even in the wilderness.
Its comfort rating of 3°C (37°F) is ideal for mild to cool nights, offering a cosy and restful sleep experience without feeling too hot or cold. This rating is based on the typical warmth needed for a relaxed sleeper, ensuring you stay warm in temperatures below 3°C. For those more cold-resistant or willing to layer up, the bag also has a lower limit rating of -1°C (30°F), which can still provide sufficient warmth and insulation for colder conditions. At this lower limit, the sleeping bag is designed to keep you from feeling cold while maintaining functionality, making it a versatile choice for various climates and conditions.
