Rab Neutrino Pro 300 Sleeping Bag (-4°C/25°F)

The Neutrino Pro 300 captures the essence of Alpine exploration. It is meticulously designed with a narrow mummy shape to minimise bulk and maximise packability, utilising lightweight, high-performance materials. This sleeping bag is well-suited for two-season, fast-and-light mountain expeditions, where temperatures can plummet overnight.

The Neutrino Pro 300 is insulated with 300g of 800FP European goose down, securely held in chevron-shaped baffles. These baffles are ingeniously crafted to use less fabric compared to conventional horizontal designs. The trapezoidal boxwall baffle construction ensures the down achieves full loft, eliminates cold spots, and enhances overall warmth. Additional baffles along the zip and around the neck further reduce heat loss, while an adjustable drawcord hood enables a snug fit around the face for optimal insulation.

The Pertex® Quantum Pro outer fabric is made from recycled nylon, providing excellent wind and weather resistance, making it ideal for managing condensation and damp conditions encountered on exposed bivouac ledges. The down is treated with a Nikwax fluorocarbon-free hydrophobic finish, ensuring better performance and moisture resistance during extended use in wet weather.

Each bag is hand-filled in the UK, guaranteeing that the down has never been compressed before use, preserving its loft and insulating properties.
