Sea to Summit Ultra-Sil Dry Waterproof Day Pack

Great, packable backpack for use while traveling. When I'm traveling, I use a crossbody day bag. This backpack ended up being perfect for my last trip. I could pull it out for use for purchases I made out during the day. Another poster noted that the straps dug into the shoulders. I didn't find this to be the case for me, but that could be because of my height (5'4") or the weight of the content I carried in it. I chose this one over the other Sea to Summit day pack for the larger container size (though it's still pretty small), rain protection, and the front ties, which can both cinch in the bag or hold something (like a cardboard tube or some other oddly shaped object). This bag worked so well on my trip that I continue to carry it around in my purse as my go-to portable bag. My only negative for this bag is its packability. Yes, it will pack as small as it shows in the picture, but it takes real work to get it there. It's not an easy or logical fit. It takes me a good couple of tries to get it back into that tiny bag holder each time. I wish the bag holder was made of a more flexible material that could then be cinched in after the bag is crammed into it.

This is a great bag. I bought it to pack my wetsuit and snorkeling gear in for a trip to the Galapagos where I would be on the go. It is truly waterproof whether it is containing a wet wetsuit that you don't want dripping on things or keeping other things dry in a boat or in rain! I will say the straps are not made for long hiking or all day use. They do hurt... But I think for the future I can create a padding to go around them. I still give it 5 out of 5 stars, for functionality size and definitely for color!!

Pros - backpack folds down very small with included stuff sack (works great as an “auxiliary” bag when I am traveling with only a larger backpack). Waterproofing seems to work well and have not had any leakage issues when in rain or paddleboarding. Cons - material is see through so bag contents can be seen by whomever. Very thin straps. Slightly pricey for the lack of material. Wish it contained some sort of inside pocket for small items.

Love love love it. I boight it for a Vacation. Absolutely perfect for the beach you just shake off the sand or just for walking around city. You can pack it into small tiny roll..it weights nothing...and you can fit so much stuff in it. Love it. Absolutely one of the best items. I wanna check if they have more stuff from this material.

Talk about deceptive advertising..... I can't comment yet on the durability of the product, but the photos and descriptions don't make any mention of the see-through material that feels about as thick as two plastic grocery bags. It comes in a tiny stuff bag, which probably makes it perfect for an emergency travel bag. I don't see it being used as a quality trail or daypack. I intended to use it as a daily bag for working outdoors. I can truly say that I would not have spent $70 on this product. I would have called it close to the $25 mark. It is big enough for a light jacket, but there are no pockets anywhere on the product.

LOVE THIS BAG! Took it to Asia and it was great for scuba and trekking around town when it was rainy. I used to have the non-waterproof version of this bag too and loved it. Packs up super small (smaller than a water bottle) and the material won't rip. Comfortable on the shoulders even when its full. Can attach smaller things on the outside if needed with the straps (wet towels).

Great purchase for a trip to Patagonia this past February. Very useful daypack while climbing in and out of zodiacs several times a day. Although the straps are a bit flimsy, they held up well. I am confident that they will hold up over the long run. There are compromises in a pack this light. It folds to a size smaller than a soda can and weighs next to nothing.

Took to Japan and used everyday for two weeks. Developed a small rip in the very top of the harness, but did not impact the seal. The storage bag could be part of the bag and about 5% larger.

BEWARE. This item is delivered in the UK by REVI as 'next day delivery'.it took well over six days ,with the system being so unreliable and the means of getting up to date information via phone or 'chat' Ive wasted six days not leaving the house, the most waste of my time I can remember. The product is fantastic and I cant sing its praises enough. I want to be clear I dont blame the supplier they sent it to depot within hours of the order being placed and kindly supported me as best they could.

バイクで移動時の雨対策に、折りたたみサブバッグとして購入しました。シンプルデザインで軽く扱いやすく、防水性と収納力も問題なし。14inのノートPC（クッションケース入り）と、A4サイズのバッグインバッグと、着替え上下一式を入れてまだ余裕あります。購入時、折りたたんで収納用の袋の中に入った状態で届いたんですがあまりの小ささに驚きました。手のひらに隠せるサイズ。ただ、どう頑張っても二度と同じように収納することができず、現在、収納時は袋からリップの部分がはみ出してます。（それでも充分小さいですが）

El material es de calidad y los acabados son buenos para una mochila ultra ligera. Le doy cuatro estrellas por dos motivos: la mochila es traslúcida, se ve lo que hay dentro, cosa que no parece viendo las fotos y la bolsa en la que viene guardada es ridículamente pequeña, imposible volver a meterla ahí. Después de dos años de uso le doy las cinco estrellas por la calidad general de la mochila

Significativement plus gros une fois rangé que la version originale (Nano), voir photo. Plus difficile à remettre dans son pochon de rangement, qui n'est plus solidaire du sac : attention à ne pas le perdre ! Présence d'un cordon de serrage dont la seule fonction réelle me semble être d'alourdir inutilement le sac. Dans les points positifs, le volume a augmenté et l'ouverture est plus large. Et ça reste un sac d'appoint minimaliste, ultra-léger et bien plus petit que les modèles concurrents que j'ai testés.

Acheté pour un voyage en août au Japon. Chaud et humide. Avec les baguettes en titane c'est mon meilleur investissement !
