For hiking, travel or school, the Mountainsmith Day TLS (Technical Lumbar System) is designed to stash all of the bare essentials (and then some) that you can’t imagine leaving home without. Made from Reforge™ recycled PET body fabric (100% Recycled) and high tenacity nylon in key wear areas to up the ante on performance. Key features include waistbelt mesh pockets, wider shoulder strap pad for messenger carry, flat profile side bottle pockets, dedicated internal iPad/tablet sleeve, and increased ergonomic fit with our Lumbar Control Point™ pad. This classic keeps getting better.

I love your products!
by Klaus on March 20, 2015
Just thought I would let you know I have owned your Day Pack (now TLS) for 12 years now and literally use it everyday. I bought the strapettes and have used it as my primary day pack on numerous month long trips to Thailand (5 times), Costa Rica, Vietnam, Japan, Mexico and Burma. I have never had any problems with it and not one stitch has become undone. I mostly used it to carry heavy camera equipment, but now its my everyday bag. Its a little sunbleached, but still works 100%.
