In short
Good for
- Budget all-round waterproof for UK hillwalking and day hikes
Strengths
- Pit zips (29.5 cm long, measured by OutdoorGearLab), a storm guard over every zip and a one-hand adjustable hood with a stiff peak
- PFAS-free DWR and over 50% recycled materials
- Women's version exists (Downpour Women's)
Weaknesses
- OutdoorGearLab says it is not the best choice for severe, prolonged storms
- Hood only partly covers a helmet (OutdoorGearLab: snug fit with partial coverage)
- Rab's page doesn't state the seam taping, so rain protection is an estimate, not a reviewed score until it does
- Does not stow into its own pocket (OutdoorGearLab)
- Only one independent review of the current model found, so weather protection and durability are estimates, not reviewed scores
- Shop pages disagree: GO Outdoors still quotes an older spec (320 g, 98 gsm fabric) while Rab and Tiso say 377 g
