The Commando (2018) was our first product and received almost universal 5 star reviews but #betterneverstops. Based on your excellent feedback, we have tweaked the Commando (previously called Commando V2) to be even better.

  • Removed the front inner leg seam, a high-risk chafing area
  • Reverse merrow stitch for a "barely there" seam feel
  • Tapered leg and more elastic leg hem to stay put
  • Waistband seam moved off-centre back to prevent coccyx rub
  • Adjusted the sizing for a truer fit (size guide here)

"Helps to combat chafing, incredibly light, very breathable and comfortable and ideal for all conditions." - Ultra168. And check out this review from Middle of the Pack Runner:

T8 review

I was surprised how well these have worked. I was looking to replace SLAB running tight that is used under non liner SLAB shorts. Extremely breathable. There needs to be a better gripper on the leg sleeve to prevent some sliding up. I have tested them in a 50k and I had no issues with chaffing but like I mentioned adjusted the legs once or twice. I would buy more as I don’t think there is a great brand in the market that makes a good pair that can compete with the SLAB running tight.

Love them. They have become my go to running underwear. Zero issues with chafing, even on long days 7+ hrs and on multi day adventures and that's were I previously had issues. As the description says they are super light and dry quickly, can a 100% confirm that. Definitely buying 2 or so more next season. I had a slight manufacturing defect on one, which made it rip at a random spot in the middle of the fabric, but the support was extremely understanding and just sent me a new one. Can't recommend enough.

Great product

This product is great for hot, humid NYC summers. Training for a marathon in the summer is kind of gross. At the end of a long run, the underwear doesn't smell and chafing isn't an issue. I'm typically wear a medium but sized up to a large per T8's instructions and am happy I did.

Both items were a great fit and at the beginning of my run I kept checking I was actually wearing shorts wearing as they are so light. During and after the run in very humid conditions there were no rubbing of chaffing of the skin, which i have found with some other shorts. Also a nice touch from the T8 team with a free pair of socks and card thanking me for my first purchase!

Absolutely love these

Very comfortable (if you tie them up right, follow the video) even when carrying 3 water bottles and phone. They dry quick, are comfortable to run in, and for me make a short for most scenarios. The inability to stably carry water/phone in other shorts has retired them to purely gym runs or runs where I carry a backpack. The blue camo design is awesome, and I'd love t8 to release a pair of casual swimming shorts with this design (which is a map of HK if you look closely at it).
