Pants like an A/C unit for your junk.
The only pair of pants you'd want to wear on a hot summer day. Ventilated, stretchy & ridiculously lightweight.
With a soft hand feel and no swoosh or shine in the fabric like you might expect from most light active pants.
Thoughtfully designed with features that are essential for adventure travel.
Stretchy waistband with an internal drawstring that can be tied outside or inside. Two small accessory loops for keys, sunglasses or whatever else.
Side zipper pocket big enough for a large phone, hidden zipper on the back right pocket, button closure on the back left and traditional front pockets with an added media pocket on the right.
All pockets have light, stretchy mesh lining that help keep everything breathable and dry super fast, making these pants perfect for when you need to hand wash and hang dry when traveling or camping.
Aesthetically minimal, as packable as they come & most of all perfect those hot a$$ days.

Regarding UPF Rating...
Our Vent Pants/Shorts technically don’t carry an official UPF (Ultraviolet Protection Factor) rating. That’s because the fabric is ventilated with extremely tiny needle-sized holes designed for maximum breathability. Since direct UV light can pass through those minuscule vents under very specific conditions, the pants can’t be certified with a UPF rating.
That said, in real-world use, it’s virtually impossible to get sunburned through them or get any meaningful UV exposure to your skin at all. For UV rays to reach your skin through those tiny vents, you’d have to be lying completely still in direct sunlight for several hours without moving at all. In normal use, there will never be any meaningful UV exposure through the fabric.
However, if you have heightened concerns about UV exposure due to skin sensitivity, medical reasons, or personal preference, we totally understand. In that case, we’d recommend checking out our Shenanigan Pants, which are a similarly lightweight option but fully UPF-rated for added peace of mind.

Pants fit perfect and are the best pants for summer hiking.
Great pants, perfect for hot weather! True fit and very comfortable.
Sick pants
I suffer from any definition in the buttock region. Therefore drawstring pants will only stay up if I have nothing in my pockets and am standing still. I was sadly going to send them back, but with a pocket knife and a light fabric ratcheting belt I rescued from $15 shorts that have seen better days, I made what I believe are major improvements. I slid the belt behind the drawstring in the fabric loop and I use both to secure the pants. The belt is not visible and the drawstring is a good secondary adjuster for added security. I still gave the Vent Lightweight Active Pants 5 stars because they seem great and it’s not your fault I have no butt.
These are truly my most comfortable pants. Also, wore them on a hot mtb ride without overheating
