It all starts with a spark of inspiration and pencil sketch that is scanned into the computer and perfected within photoshop. One design can often take up to 80 hours to complete from start-to-finish: it's all in the details.

These are the best pants I have owned so far. Everyone asks where did I get them from. Feel amazing, movement is as if I’m not wearing anything at all. Super soft, stretchy and stylish!

Awesome leggings

I do Olympic weightlifting, gym based training and yoga in these leggings. They get a lot of use and I’m hard wearing on them. They are just fabulous in every way and the design is awesome. It’s so good to find hardwearing leggings which can cope with all my activities and look amazing at the same time. So much so, I am a repeat customer based in the UK.

Thank you so much for your awesome review! We are stoked to hear that the Triathlon leggings work well for all of your workouts and that you're loving the designs. We really appreciate your feedback and are so happy you're a part of team Werkshop, we couldn't do it without you!! xoxo, Allison

Love them! Second skin fit and feel!

Was a little concerned how they would fit anatomically but they proved very comfortable and great compression!

Hey Frank! Thanks so much for taking the time to leave us a great review! So glad to hear that you're happy with the fit of your leggings! Enjoy them! xoxo, JJ

Bought these not really knowing what to expect because I have never felt the type of material they use but my expectations were exceeded I not only love their shorts which I own but these leggings are amazing. You don’t feel any restriction in your movement and after awhile they just stick to you as a second skin and form to you. I highly recommend the triathlon leggings and also I am a guy so dudes these are comfortable for us

Hey Robert! Thank you for the stellar review! We're thrilled to hear that you're enjoying your new leggings so much and grateful that you decided to give them a try! We hope to have the opportunity to make you happy again in the future! xoxo, JJ

Men can wear these too!

I wish I would have tried these sooner. I wear these for my ashtanga practice and want to keep wearing them all day. I have these in large full length. I Am 6'1" with a 32 waist. They naturally end above my ankles but I can still pull them over my heels if wanted. I machine wash them cold and line dry. They are about a month old and look brand new. I wear them twice. Week as of late. Men, go for it.

Hey Brodie! Thanks so much for the killer review! It so great to hear that your leggings are serving you so well and that you're enjoying the fit and performance. Enjoy! xoxo. JJ
