Customer Images

Here's what customers have to say

The product is a lightweight, packable rain pant that provides effective protection for activities like hiking, biking, and fishing. Many users find it waterproof, breathable, and comfortable, with a good fit. However, some note it may not be durable enough for very rugged terrain or prolonged heavy rain, and can be prone to ripping or wearing out in the crotch area if not sized up. Overall, it seems to be a good choice for occasional use in light to moderate rain.

Breathable, lightweight, rain protection

Familiarity:: I've used it several times

I’ve only had the chance to wear these in light rain/ wet conditions, but so far, they hold up very well! They’re super light and breathable, making hiking and general movement easy.

Good value, runs a little small

Order a size larger than you think you need. The size guide doesn't reflect the likelihood that you'll be wearing another pair of pants underneath. Mine fit, but they're a tight fit to pull up over a pair of jeans.

Must have rain pants

Amazing pants for the outdoor enthusiasts! These are great rain pants that are super light and pack down small. Love the versatility for my outdoor adventures. Only improvement I would make is a little higher of a side zipper but all in all have worked great.
