Outdoor Research Echo
Reddit take
AI summary of the Reddit excerpts below — not a quote
The Outdoor Research Echo is a popular choice in the ultralight community, primarily valued for its extreme breathability and lightweight construction. It is frequently cited as a top-tier option for high-exertion activities in hot, dry climates where its thin fabric allows for rapid sweat evaporation. However, the product is polarizing regarding its protective capabilities; while some users find it sufficient for desert use, others criticize its low UPF rating and poor performance once the fabric becomes saturated with sweat.
Pros
- Extremely lightweight and packable
- High breathability suitable for high-exertion activities
- Fast-drying fabric that excels in hot, dry conditions
- Thin material provides excellent airflow
Cons
- Low UPF rating may offer insufficient sun protection for some users
- Fabric can become overwhelmed and clingy when heavily saturated with sweat
- Thin material is reported to wear out quickly under heavy use
- Small hood design
- Unflattering fit according to some user reports
Caveats
- Opinions on sun protection are highly mixed; some users report no issues in desert environments while others claim it does not block enough UV rays.
- Performance differs significantly between dry heat and high humidity, where it may require a mesh base layer to manage liquid sweat.
Best for
- High-exertion hiking in hot, dry climates
- Ultralight enthusiasts prioritizing weight savings over durability
- Layering in environments where maximum airflow is the priority
Avoid if
- You require high UPF-rated sun protection for long-duration exposure
- You primarily hike in high-humidity environments where the fabric may 'wet out'
- You need a garment that can withstand significant abrasion or rugged use

Agreed, but spare underwear can be had for under 2 oz. T8 commandos, Uniqlo Airism, OR Echo
boxers can be much lighter. T8 commandos, Uniqlo Airism, or OR Echo
I like both the Echo and Lifa. ... Echo is great when it's hot hot; sweat evaporates immediately.
Something like an OR Echo brings the cfm into a functional range for high exertion.
I’ve got a OR echo now and it is very good- they had it on sale at Valley and Peak a few months ago
And yeah, you're not alone - I don't even have a gut but my OR Echo puts on 30 pounds in pics!
IMHO, the OR Echo is too easily overwhelmed by sweat. Many people rave about it's breathability, but once it's wetted out, in my experience, it doesn't do too well.
In fact, I find that the Echo *needs* a mesh layer in hot/humid environments or it quickly becomes overwhelmed with liquid sweat.
the OR Echo I normally use is a very thin and breathable fabric that would not add much warmth on cold weather.
OR Echo breathed better for sure but did not protect me from the sun and wore out fast for me.
