## 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. Though the design honors the 40+ year history of this waist pack and has not changed much in shape, modern features make this version of the Day the best yet. We have heard this product used for just about anything including a 3 day backpacking trip in the Sierras. Where will this fanny pack take you? To bring you peace of mind for your backcountry investment, Mountainsmith offers a lifetime warranty on their products. If you have had a Day pack in your lifetime, you already know how useful it can be. If not, what are you waiting for?

Review: If you only want to buy one lumbar pack, pick this one. - Excellent build quality, well laid out features, very comfortable to wear. Holds a decent amount, too. It's not too heavy, but it'll take all the stuff you need for a day out hiking. The pull tabs on the zips are easy to use (even with gloves). Now, I will grant that it's not as cheap as some lumbar packs out there, but the quality and design, not to mention the warranty, make this an easy choice. It's well worth the price.
Review: Large and comfortable - I needed a pack to hold camera gear, water. Etc., things needed for a day hike. This seems well made with a thick material. It is comfortable on my waist but also has a good shoulder strap. It will actually hold my camera with 600m lens which surprised me. This makes it easy to get everything to the car. I have used it for a couple of short birding hikes and found I don’t notice it is there until I need something and it is easily at hand. All the various pockets make it easy to reach what you need. This is lightweight and gives me more than enough room for day hikes.

### ⭐⭐⭐⭐⭐ Best Day Pack EVER!
*by L***N on February 3, 2024*

This is the perfect day pack: plenty of room in the large areas of the pack, even for a water reservoir, if you prefer that over water bottles. I like keeping the heaviest things I carry (like water) closer to the center of my body, so I put lighter things (rain cover for the pack, xtra socks, rain jacket, sandals, etc.) in the secure water bottle holders on the outside of the pack. Anyway, there's generous room in the main compartment for extra clothes, first aid kit, and a meal, plus things like binoculars, journals, etc. Plenty of secure/zippered areas for must-not-lose-on-the-trail items (car keys, wallet, etc.) The drop down outer flap is great for a mid-weight jacket, or rain jacket, that needs to be readily available depending on the effort/heat I'm putting into the hike. The belt: come on! this is the best day pack belt on the market. Wide and lots of smooth hip padding and two additional external compartments for smaller items (though the zippered pocket does hold my iPhone 15, so it's not small!) on the belt at the front of the body. And the very best part: I have to wear NOTHING on my mid and upper back, where I generate a big percentage of heat while hiking. Also, my upper body can move without being encumbered by a pack--sometimes required on rock hops and in forests. When I travel by air to places I'll be hiking, the pack is my under-seat bag. My other good-hip-belted day packs with the same capacity could not fit under the seat. Very high quality craftsmanship mean my first one only finally wore out after 25 years of hundreds of miles of travel/hiking. (It's still in good enough shape to be my dog's travel bag.) I almost forgot: the bottom straps can hold a bottle of wine, a tarp, a pad for sitting, additional light shoes, towel, bathing suit, or many of the trail-specific things you like to take depending on your destination (baguette, anyone?)
