The popular Dagger OSMO™ tent has never been more roomy or environmentally friendly.

NEMO, a renowned outdoor gear company, has announced that its popular Dagger OSMO™ tent is now a bluesign® PRODUCT. This certification underscores NEMO’s commitment to sustainable manufacturing and the use of clean chemistry, adhering to the industry’s most stringent environmental and worker safety standards.
The 2025 Dagger OSMO is crafted from solution-dyed, 100% recycled fabrics that are free from PFAS and fire-retardant chemicals. This new design offers enhanced livable space without adding extra weight, thanks to custom hardware and meticulous attention to detail. Available in 2- and 3-person capacities, the tent has a minimum weight of 3 lbs. 5 oz. for the 2P version and an MSRP of $499.95.

Sustainability at Its Core
The bluesign® PRODUCT designation represents one of the highest standards of sustainability in consumer goods, ensuring that harmful chemicals are eliminated at the start of the textile supply chain. This achievement is particularly significant for tents, a category known for its complex material requirements and high-performance standards. Traditionally, elite backpacking tents rely on chemical treatments to enhance durability, water resistance, and UV protection. However, NEMO’s OSMO fabric has successfully bypassed these harmful substances while maintaining top-level performance.

Innovative Design Features
The Dagger OSMO introduces several advanced features, including:
- Elements™ Hardware: A custom pole structure that expands interior space, door openings, and peak height.
- Axial™ Corner Anchor: Allows for quick and easy setup without re-staking.
- Stash™ Volumizing Strut: Provides 22% more usable storage space in the vestibules with minimal added weight.
- Divvy Cube™: An improved packing solution that fits efficiently in a backpack and can be compressed for weight-sharing.
