This ultralight sleeping bag is built for backpackers who value efficiency, making it an excellent backpacking sleeping bag for thru hikes, fastpacking, and three season camping.

Advanced Materials for Lightweight Performance
This 25 degree sleeping bag uses ultralight NetPlus nylon ripstop made from recycled fishing nets, reducing weight while improving durability. Paired with 850 fill down sleeping bag insulation treated with Downtek water repellent technology, it maintains warmth even in damp conditions, making it a reliable 3 season sleeping bag.

Thermal Efficiency Without Extra Bulk
Big Agnes Signature Diamond Quilting limits down migration while reducing stitch lines to preserve loft and warmth. The mummy profile and ergonomic footbox allow faster heat retention, making this lightweight sleeping bag ideal for cold nights when every ounce matters.

Minimalist Design Built for Real Use
A streamlined hood with a low profile cordlock keeps warmth in without limiting airflow. The half length center zipper allows easy temperature control while reducing weight. An insulated zipper and draft collar further improve thermal performance, creating a highly efficient Big Agnes Fly Creek sleep system.

Packable Comfort for Every Overnight Trip
This Big Agnes sleeping bag includes both a mesh storage sack for long term care and a compact stuff sack for trail use. For maximum compression, it pairs easily with a compression sack, making it a smart choice for hikers building a compact gear kit.
