## Description

Lumbar pack that started in the 80s. Daypacks are a favorite of hikers and outdoor-driven travelers and continues to live in modern incarnation. Versatile and versatile, this pack tends to be treasured in all outdoor enthusiasts gear closets. However, it will not last as long as you can use it daily as a hiking pack, disc golf bag, messenger bag, office briefcase, carry-on travel solution, diaper bag, etc. Made from extremely durable ripstop nylon fabric, the Day lumbar pack is an outdoor security blanket that will keep your adventure miles around the world. The design honors the history of this waist pack for over 40 years and has not changed much in shape, but modern features make this version the day the best ever. We think this product is used for almost any purpose, including a 3-day backpacking trip on the Isle of Sierra. Where will this fanny pack take you? To bring peace of mind to your backcountry investment, Mountainsmith offers a lifetime warranty for its products. If you have a daypack in your life, you already know how useful it is. If not, what are you waiting for?

Review: モデルチェンジ前のツアーも所有しています。 ツアーには、レインウェア(上衣)、フリースベスト、サーモス水筒(熱湯)、ファーストエイドキット、おにぎり、スイーツ、ドリップコーヒー、飲料を入れていますがおにぎりやスイーツが潰れます。 なので今回は新型のDAYを購入しました。容量が増えているので水筒に変わってガスOD缶とクッカーを入れる事が出来ますし、スイーツも安全に持ち運ぶ事が出来そうです。 残念な所 小分け用のポケットがほぼ無い。 ウエストベルトが大きい(長い)、私はやや細身な日本人男性です、ウエストベルトがギリギリ締まりますが、細身な女性だと締まりきらずに緩いと思います。
Review: 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.

*by D***. on December 17, 2020*

This pack is very versatile! It has a ton of room for all of your essentials and then some. It’s very comfortable to wear with plenty of padding, and you can add the shoulder strap if you that little bit of extra support. I use this as a day pack, 1-2 day travel bag, and a camera bag for doing photography shoots. I highly recommend this pack and am also considering purchasing the 9 liter as well.
