Estimate from maker's specs
In short
Good for
- Just-in-case rain cover for mountain hikes in uncertain weather, packed in the rucksack
- Quick to pull on over boots in a sudden shower, using 3/4-length side zips
- Walkers who want a soft, flexible 2.5-layer fabric
Strengths
- 20,000 mm hydrostatic head and 20,000 g/m2/24h breathability (Rab)
- 262.5 g in size M
- 3/4-length side zips with a hook-and-loop storm flap, so you can vent without the flap billowing
- Articulated knees and a longer-length gusset
- Part-elasticated low-bulk waistband and drawcord-adjustable hem
Weaknesses
- 3/4-length zips do not open the whole leg, unlike the full-length zips on Rab's Downpour Mountain pants
- 2.5-layer 50D fabric at 122 gsm, against 148 gsm for Rab's 3-layer Firewall pants
- Waistband is part-elastic with drawcord only
