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.

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.

Review: 男性向けの商品だと思う。 - 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。
