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 reduces carbon emissions by up to 30% compared to virgin polyester. Nike diverts an average of 1 billion plastic bottles annually from landfills and waterways.

Side thigh pockets are too loose
GeromeC638276833May 11, 2026
The fit, looks, and comfortability of these are great. It has a lot of pockets. The only issue is the large side pocket - it is way too loose to put your phone in. I have other Nike tights and the side pockets are way tighter than these. The material where the side pockets are on these tights causes your phone to bounce and slide like crazy on runs. I wanted to love these tights, but I hate not being able to hold my phone in the side thigh pocket
Bury me in my Lava Loops

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
