STOVER 防水ドライバッグバックパック 25L 男女兼用 ロールトップ 軽量 ドライストレージバッグ 旅行 水泳 ボート カヤック キャンプ ビーチ用 (オレンジ)

Good size, easy locking clasp. I like that you can use it as a backpack which I haven’t done yet but nice features.

Really solidly constructed-- the seams are welded with lots of overlap, and the material is (very) abrasion and puncture resistant. The bag is definitely waterproof; when doing the roll top, you need to collapse the internal volume first since it's airtight and can't expel air anywhere except the main compartment opening. Assuming that it isn't filled with rocks or something else denser than water, this bag will float if submerged. The handle and d-ring attachment points are also well constructed and reinforced, and the material is thick enough that the bag keeps it's shape. The top handle is weight bearing, so you can use it as an easy attachment point for clipping a carabiner and hauling it up a cliff face. Using this as a climbing bag--I like how bright it is, which makes it easy to spot/find outdoors, and also reflects enough sunlight that the inside stays relatively cool. The abrasion resistance for dragging it over rocks is awesome, and the backpack straps are quite comfortable. This isn't an ultralight bag, but it's pretty simple in design and the cylinder shape is material efficient, so it's actually pretty lightweight. The large top opening makes it easy to pack, and I like the cylinder shape which accommodates two pairs of climbing shoes better than other bag shapes I've had. Keeps my climbing stuff dry, and has an external mesh pocket for when I take my shirt off!
