Review: Rab Phantom Waterproof Jacket

In a waterproof jacket, especially for higher intensity activities like trail running or fast hiking, I prioritize minimal weight and bulk without compromising on protection from the elements. Breathability is an absolute must, and the jacket should pack down small to fit into a vest or small pack. Durability is definitely a consideration, but I’m willing to trade some robustness for weight savings.

I tested the Phantom during several spring trail runs in the Lakes, encountering everything from light drizzles to sustained downpours. In light rain, the jacket performed admirably, shedding water effectively and keeping me 100% dry on the inside. During heavier rain, after about an hour, I did notice some dampness seeping through the front zip area.

Breathability was impressive; even during intense uphill efforts, I didn’t experience the clamminess you can get with shells. The fit and stretch in the fabric allowed for decent movement, and the jacket didn’t ride up or flap excessively.

The ultra-thin fabric does raise concerns about realistic durability.

ULTRA-LIGHTWEIGHT – At just 116g, it’s one of the lightest waterproof jackets available

PACKABILITY – Packs into its own hood, forming a compact bundle that’s easy to stow.

BREATHABILITY – Performs well during high-intensity activities, preventing overheating.

MINIMALIST DESIGN – Stripped-back features reduce weight and potential points of failure.

Priced at £175, the Rab Phantom offers good value for those seeking an ultra-lightweight, packable waterproof shell. While it may not be the most durable option for prolonged use in harsh conditions, its performance in fast-and-light scenarios makes it a worthwhile investment.
