Klim Summit LS Tech T-Shirt 4.5 5 13 13
Excellent base/mid layer / exceeded all expectations This is an excellent base/mid layer. This is not an ultra thin shirt. It has some weight to it and is perfect for cool weather. It is high quality and very well made. The front and back are made with a polyester micro-grid knit that traps heat into the shirt. The sides are stretch panels of poly/spandex which breath very well. This is a very comfortable shirt that just works very well. I found the sizing to be spot on. This shirt looks great on and off the bike. 100% satisfied and I highly recommend, especially at the closeout price. Great value. January 26, 2016
Excellent All-purpose Mid-layer I just completed a week long road trip and exclusively wore these shirts. I rode in temperatures from 34 to 104F. This paired with my Klim Badlands jacket kept me comfortable above 50 and adding a mid-weight fleece down to 34. Sizing - The shirt is true to size, but I went one size up to wear jersey style. Easy care - Wash and fast drying allowed me to get by with less clothing. Value - I bought them on sale so it was a great value. Regular price will still get my business in the future. Highest recommendation September 21, 2015
Solid undershirt Great shirt all the way around - breathes well as advertised! July 6, 2015
Excellent mid-layer that can be used off the bike It works well as the mid-layer over base layer with my Badlands Pro jacket, or as a standalone shirt/jersey off the bike. It is warm and comfortable. June 24, 2015
Nice shirt, not for hot weather I bought this Klim long sleeved t-shirt thinking it would make a good base or mid-layer shirt for warm weather. However, it was much thicker than expected. It should make a warm mid-layer for cooler temps. June 1, 2015
Not for warm weather This is definitely a very good layer for temperatures under 60F. Above that and it gets too toasty. It is extremely comfortable under your jacket and fits as advertised. April 20, 2015
Nice riding underwear. Comfortable and not dorky. These work well in NorCal. March 2, 2015
Stylish Base Layer I purchased the Summit for its style and features. I do not like zippers and wanted a base layer that was more beefy than the Aggressor Base layer (which I own too). The shirt runs small in my opinion for I ordered the same size that I wear in the Aggressor and it was too small and had to return it. Otherwise it is a good choice for someone that wants a base layer that can be bumped up to a mid layer for extra warmth and look good too. December 18, 2014
