UltrAspire LUMEN Ally


The Lumen Ally allows you to combine our Lumen and waist belt products. This waist belt attachment is perfect for anyone wishing to use a Lumen light and carry a water bottle on their waist at the same time. Like all packs in the waist pack line, the Lumen Ally features our breathable webbing which allows moisture to evaporate and will not slip once adjusted to fit. This piece also utilizes a stretchy mesh pocket behind the light adapter giving you capacity for a cell phone, energy foods, backup batteries, or other small essentials. A pocket located below the light can house an extra battery. The Lumen Ally allows you to run with speed and confidence like you would during the day while also carrying your preferred hydration. Light and hydration belt not included.
