Nitrous

The Nitrous Sleeping Bag is built for lightweight adventures, making it the ideal choice for summer trips and shoulder-season overnights when every gram matters. Its tapered rectangular cut with a box-shaped foot offers a comfortable balance of space and warmth, while still packing down remarkably small. Insulated with premium 800–850 loft hydrophobic down (Non-PFC treated) and constructed with box wall baffles, the Nitrous delivers impressive loft and thermal efficiency. The 10D Vapour Vent (V2) shell fabric is soft, highly breathable, and naturally downproof, finished with a Non-PFC water-repellent treatment for extra weather resistance. For convenience, a full-length anti-snag zipper opens from both ends, giving you easy access and customizable ventilation on warmer nights.
