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 enthusiast’s 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 fabric, the Day lumbar pack will become your outdoor security blanket as it logs hundreds of thousands of 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.

To bring you peace of mind for your backcountry investment, Mountainsmith offers a lifetime warranty on their products.

### ⭐⭐ ショルダーベルトが長すぎる
*by  on Reviewed in Japan 16 May 2023*

2年以上前に購入。ショルダーベルトが長すぎで、身長178cmで最も短く調整して何とかちょうどいい位。背の低めの人はもうどうにもこうにも長すぎだと思う。おそらく「TOUR」なら良いのかもしれないが、「DAY」は本体そのものが長いのでベルトが余ってしまうのだ。また、一番外側のゴムのフックが外れやすいし、機能的に使い勝手も悪い。旧モデルも持っているのですが、総じて旧モデルの方が優秀なバッグであった。この現行モデルが出てすぐに買ったのですが、これら欠点がマイナーチェンジされることを期待したい。

### ⭐⭐⭐⭐⭐ its an odd little pack
*by  on Reviewed in the United States 30 November 2022*

Unlike an internal frame pack, these don't have flexible metal that can be bent to conform to the specific lumbar of your back. instead, they curve a bit, but the taller the pack, the more unaligned it becomes to the lumbar portion of your back, depending on your height. Unlike an internal frame full pack you don't have a webbing to cover the cureves or a framesheet to just bypass the lumbar cure. For me the tour feels fine, but the Day feels like there is a gap (even though someone looking at you probably wouldn't see it). Its the weight sitting on your hips compared to the lack of such on your lumbar. Just makes it feel like there is a gap.Both fit fine, but I find myself gravitating toward the Tour the most often. Unless I am going to be carrying kit for the family, then it's the day or if I am commuting with over ear headphones, the Day wins hands down.I like these because the family can easily access it when it is on. Also, the shoulder strap really helps with weight distripution and with making it a quasi messenger bag when needed as such.

### ⭐⭐⭐⭐⭐ Best Day Pack EVER!
*by  on Reviewed in the United States 3 February 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?)
