Graph Ultralight Base Layer

Graph Ultralight Base Layer


Only one atom thick and stronger than steel, Graphene is truly a wonder material of our age. Boasting a wide range of applications, we leverage its thermal conductive properties to increase comfort next to skin. Sometimes referred to as a smart material, Graphene has both cooling and thermal properties. The Graph Ultralight Base Layer dynamically regulates your body temperature by dissipating your body heat across the yarns and throughout the surface area of the garment to maximize comfort across a wide range of conditions.


At the height of summer, staying cool and comfortable under all that gear becomes a challenge. No matter what you are wearing, it always feels like too much. That’s when the quality of your layering system really shines. And, like all good systems, it starts with a solid foundation. The Graph Ultralight Base Layer is just that.

Low-profile bonded seam construction allows it to layer seamlessly under armor for quick-drying moisture management. With a drop hem, additional torso length, and longer short sleeves, it is designed to directly interface with your armor straps to reduce chaff and stay tucked in while riding.

To further enhance performance, we’ve incorporated graphene, one of the world’s most advanced materials, to improve thermoregulation and keep you feeling comfortable even in the hottest conditions.

  • Graphene Thermoregulation Technology 
  • Sew-free Bonded Seams for reduced chaff under armor    
  • Anti-Microbial/ Anti- stink Treatment
  • Moisture wicking and quick drying
  • Tagless Heat Transfer Labels
  • Anatomical shaping for fit and comfort
  • Drop Hem to stay tucked in while riding
  • bluesign®-certified material 
  • Ethically produced in Bangladesh
  • Graphene Enhanced Polyester Mesh - 90% Polyester, 9% Spandex, 1% Graphene 140g/sm bluesign®-certified material

The Graph Ultralight Base Layer is designed to be worn under body armor.

Graph Base Layer

This layer is perfect to wick away sweat and extremely comfortable, especially if you have under armor


This shirt is unreal. The way it manages temperature and moisture under my obnoxiously warm upper body armor is glorious, and it dries so fast! Unfortunately the antimicrobial coating didn't last forever on my first one but it does still fit exactly as perfectly as it did when I first got it! As soon as I got my new one though, I was shocked at how it kept me un-smelly for a nearly embarrassing number of days into an 8-day offroad camping trip. In fact, I wore it for more days in a row than I planned for and it never smelled at all!

Excellent quality, would recommend.

I have 3 of these in different colors and where one every day for my daily commute. All three have held up pretty well over the past year, however the welded seams in all 3 shirts have come apart in the arm pits. I've used various textile glues in attempt to re-glue the seams. Maybe future versions could have some stitching in those areas top prevent the seams from coming undone.

With that said, I will continue to happily where the shirts until they fall apart, have certainly gotten my money's worth, and will purchase more in the future.

Tight sleeves, lightweight shirt

Haven’d had it long but seems like it’s typical Mosko quality with its expected durability. Sleeves are surprisingly tight on the arms, almost like a sock on your upper arm. I forget about it while riding and it’s less material bunching if layering. Just feels weird off the bike. The rest of the fit is spot on. I’m 6-3 225lbs wearing an XL. I like it, just trying to stretch the sleeves out a tiny bit with wear and movement.
