Overview

The Sea to Summit Boab Synthetic Sleeping Bag is a thoughtfully designed 2-season option for outdoor enthusiasts who value comfort, durability, and responsible materials. Its roomy, contoured rectangular shape is especially friendly for side sleepers, providing generous shoulder room without unnecessary bulk.

Comfort, versatility, and real-world use

Designed to adapt to varying temperatures and environments, the Boab features a full-length zipper that runs through the footbox, enabling easy conversion into a lightweight blanket for lounging around the campfire or tackling cool evenings in a sleepless tent. Dual zipper sliders and a shoulder snap give you customizable ventilation, so you can dial in airflow and warmth as conditions shift. Whether you’re camping by a river, fishing at dawn, or trekking after sunset, this bag is built to move with you.

• Ventilation options help you balance warmth and airflow for a comfortable night outdoors
• Snag-free operation and a draft tube minimize cold drafts and zipper snags

Materials, sustainability, and build

The shell and insulation use 50-denier recycled polyester fibers certified by bluesign, with a non-PFAS DWR finish to shed moisture. This combination yields a durable, lightweight bag that aligns with responsible manufacturing practices. The Boab is part of Sea to Summit’s commitment to sustainable outdoor gear, so you can enjoy your adventures with less environmental impact.

• RCS-certified recycled materials reduce environmental footprint
• Non-PFAS, water-repellent finish helps keep you dry in damp campsites
