夏の日帰りの登山で1ℓステンレスボトル1本、500mℓペットボトル3本、おにぎり4個、500mℓペットボトル4本対応クーラーバッグをパッキングしてもダウンジャケット1着分余裕有り。山小屋一泊登山なら全然問題なし。背中がメッシュなってて蒸れにくく風が吹くと凄く快適。冗談抜きで真夏の登山で真価を発揮する。

I have been using Osprey back packs for many years and this new one didn't disappoint. Good size for a day pack. Excellent quality.

Zaino perfettamente equilibrato e versatile, capienza adatta a giri in giornata o anche a 2/3 gg. Colore davvero stupendo (blu perlato nel mio caso). Osprey qualità sempre al top, e uno sviluppo del prodotto che si vede soprattutto nei minimi dettagli. Venditore super gentile, spedizione veloce ed imballo davvero ben fatto. Grazie

I have the ladies version of this bag and love it, and my husband loved all the useful pockets and adjustment options, so I got him this for Christmas. He really likes it, only complaint being that it's difficult to reach around for the hip pockets for him. Nice colour and of course excellent quality. More than enough for day hikes. I got him the same size as me but he probably didn't need this one, I just carry more as we hike with children and I always carry more than I need 😅

171cm、70kgの私にとって、5つ目のオスプレイは、ストラトス34L、サイズO/S（46〜56cm）。軽くて背負いやすく、コンパクトで合理的なパッキングと背面の換気の良さは最高。レインカバーまで付いているのは、使用場面を体感して作り込まれている証拠。山だけでなく、旅行や買い物にも重宝しています。
