## Description

The lumbar pack that started the craze in the 80s, the Day pack lives on in its modern incarnation as a favorite of hikers and outdoor-minded travelers. With a broad swath of versatile uses, this pack tends to become a cherished possession in every outdoor enthusiastâs gear closet. However, it does not stay there long as it gets used daily as a hiking pack, disc golf bag, messenger bag, office briefcase, carry on travel solution, diaper bag, and whatever you can think of. Built with ultra-durable ripstop Nylon fabric, the Day lumbar pack will become your outdoor security blanket as it logs countless miles adventuring with you around the world.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great lumbar pack
*by F***S on June 16, 2025*

Needed a larger lumbar pack for long hikes. This pack has ample room for food, water, and other items you wish to carry. Recommend strapettes for pack which keep it close to your back and make it easier to carry the additional weight. Has many uses other than hiking such as fly fishing or day hunting pack.

### ⭐⭐⭐⭐⭐ Great Pack
*by J***  on June 12, 2025*

### ⭐⭐⭐⭐⭐ Perfect size
*by C***Z on June 2, 2025*
