The other day, on a sudden whim to organize my cluttered gear, I headed to the home center without much thought to buy some wood and started a DIY project on the fly. I quickly sketched out a design for a shelf, and enjoying this long-lost feeling made me realize how much I really do love making things. It brought back memories of my old job and felt very nostalgic. (Actually, I used to work in interior construction! Haha.)
Thanks to that, I was able to create proper spots for the gear that wouldn't fit, and I’m quite satisfied.
Having belongings that don't fit is a common issue when heading to the mountains, but RAWLOW MOUNTAIN WORKS has just released an item to solve that very problem. I’ve been using it myself, and it’s incredibly convenient—not just for outdoor activities, but also for travel and daily life.
【RAWLOW MOUNTAIN WORKS】Storage Sack

Price : M : ¥3,000-(excl. tax) / L : ¥3,200-(excl. tax)
Color : Black , Brown
Capacity:M : 5L / L : 8L
Material(Main):Spectra X-Grid (200 denier)
Expanding your pack's capacity
When you head to the mountains, don't you ever find that while you packed everything neatly on the way there, your stuff no longer fits in your pack on the way back, even though you should have less gear?

The savior that will help you out is this Storage Sack. It uses 200-denier Spectra X-Grid as the main material, which offers excellent waterproofing and tear resistance. You can secure it using the center daisy chain and side loops, allowing you to easily expand your storage by placing it on top of your backpack.

You can increase the capacity of a 36–42L Antelope to about 50L, or a 26–28L Bambi to about 35L. It can also be attached to other backpacks, which is the beauty of its versatility.

When not in use, it folds up neatly for compact storage, and it’s also very helpful for packing. I put things I use often—like cold-weather gear, trail snacks, sunglasses, a compass, and a headlamp—inside and pack it at the top of my bag. Since UL backpacks have such simple designs and often lack lid pockets or storage compartments, putting bags like this inside makes things easier to access. Because it opens wide when you unzip it, the stress of searching for items disappears. As a somewhat lazy person, this is an item I truly value.
Great for bicycles, too.
The L-size Storage Sack fits perfectly and neatly into a WALD 1372 Front Basket 37 (Small). By using the center daisy chain to strap it down with RAL Pack It Right Straps, you don't have to worry about it falling out of the basket.

The M-size Storage Sack fits nicely into a SALSA CYCLES Anything Cage or a BLACKBURN Outpost Cargo.

Not only is it perfect for the mountains and cycling, but it’s also very useful for organizing luggage for daily life and travel. This Storage Sack, which can be used for both outdoor activities and everyday life, is sure to be your savior! It’s incredibly easy to use, so it’s an item well worth trying.
