Great products,great fit and great colors!
Their customer support is 10/10! I recommend Lobtree strongly.
Really enjoying my baselayer. The craftsmanship is top notch and fit is as described. I much prefer my Lobtree set (hoodie and leggings) compared to the other Alpha Direct pieces I have (shirt, hat, socks) because the fit and quality are superior. Happy to support Canadian small businesses and have sent many friends this way when they ask about my hoodie. If I find a need for more AD products, I'll definitely start here. Thanks Nick!
Really happy with my purchase. Used this as a lighter and warmer replacement for my merino wool base layer. Nick was amazing in helping me size my purchase for what I wanted to use it for. Would buy again from Lobtree.
Warm and comfy
This kept me warm in Cold weather (-25°c)
