## Description

The original technical hiking lumbar pack, now with unprecedented strength after more than 40 years Made from highly durable ripstop nylon fabric, the Day Lumbar Pack is both versatile and comfortable For hikers, disc golfers, commuters, tailgaters, park rangers, birders, and more This pack has the carrying capacity to meet all your needs The large main compartment has a divider large enough to hold a tablet, and the large water bottle pockets on both sides can easily accommodate 1L bottles The outer pouch allows you to store and easily access essential items With the Delta Wing compression system, bring the pack closer to your waist

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.
