Stay Dry

Nike Dri-FIT ADV levels up our sweat-wicking technology with advanced cooling and zones of breathability to help you stay dry and comfortable. Smooth, stretchy material offers a locked-in feel as you move.

Stay Prepared

Three mesh waistband pockets, a pocket on the brief liner and two drop-in pockets let you store trail essentials like energy gels and lip balm. The zip back pocket fits most phones. And the two elastic loops on the back of the waistband can hold trekking poles or a discarded layer.

How This Was Made

The recycled polyester used in Nike products begins as recycled plastic bottles, which are cleaned, shredded into flakes and converted into pellets. From there, the pellets are spun into new, high-quality yarn used in our products, delivering peak performance with a lower impact on the environment.
In addition to reducing waste, recycled polyester produces up to 30% lower carbon emissions than virgin polyester. Nike diverts an average of 1 billion plastic bottles annually from landfill and waterways.

Bury me in my Lava Loops
GarrettN25965925430 Apr 2026
I have the previous generation of the Lava Loops. Correction, I have 4 pairs of the previous generation of Lava Loops. I've never found a half tight that works so well for, well, everything. I don't even run trail much. I'm an amateur marathon runner who has to carry fuel, ID, phone, keys, etc. depending on whether or not a race has a bag check. These tights have six (6) pockets! The inner liner is similar to the running half tight so you get the exact same benefits there. I have sensitive skin and I never chafe in my Lava Loops thanks to it. I'll be buying more pairs, for sure.
Brilliant Shorts

These feel very durable and comfortable. Slightly heavier in hand compared to the Aeroswift half tights but no issues when wearing them tbh. Loads of great storage and great quality drawstring. Glad I got them for sure. I got a medium and that’s the same size in other Nike shorts. Perfect for training and racing
The perfect shorts for the trail.

Absolutely the best trail running shorts I've ever come across. Started the Kosciuszko Miler in a pair last year and never changed them - so comfortable and zero rub or chaffing. They run slightly large so in every other pair of shorts I am an "M" in these I am a "S" and I knew that on the advice of someone else who had a pair. Highly recommend.
