So far I have been loving the tech leggings. I was concerned about the low back rise initially, but I've only really found it to be annoying once or twice. It rides below the waist belt of my harness, which is actually more comfortable than the other leggings I have worn - which rub against my harness where the seam lays. I'd rather have the comfort and flash some skin once in a while than the discomfort of rubbing against a high waisted seam!
Other than that, I have put these things through the ringer trad climbing and sport climbing, and they've performed really well. No tears in the softer material like my other climbing leggings, and then knee/buttpads barely scuff. I have looked far and wide for durable climbing leggings, and these are truly one of a kind. Plus, they're a rad color!! Finally no more earth tones!!! I will be buying another pair as soon as my size comes back into stock.
Thanks NW Alpine, keep it up. More bright colors would be SICK!!
