Sea to Summit TPU Accessory Case
The TPU Accessory Case is exceptionally resistant to the demands of the trail or river. Welded construction and a super reliable roll-top closure with triple fold and double hook-and-loop fastener provide fully waterproof and dustproof performance. The PVC-free TPU material is strong, durable, flexible and resistant to UV and extreme cold—so it can be folded numerous times for pocket storage without cracking or discoloring. Designed with top corner anchor points for versatility.

Works Great!
[This review was collected as part of a promotion.] I like the product. It is durable and definitely waterproof, however, I purchased the TPU Accessory Case because my Samsung S24 Ultra would not fit in the TPU Guide Waterproof Case for Smartphones. However, it does not fit real well in this one either. It fits, but to roll it the recommended times to have the velcro meet up, is pretty tight. My only complaint is that they do not make waterproof cases for larger phones - otherwise, the product itself is 5 Stars!

Accessory Case
[This review was collected as part of a promotion.] Love the confidence of being able to have my cell phone with me on the water. Another method of calling for help as well as the marine radio. I use the cord to hang it around my neck and then tuck into my life jacket. No problem using phone while in the case. Recently had a defective one replaced under warranty - a quick and easy thing to do. Sea to Summit were great.

10/10
This thing is amazing! I work for a whitewater rafting outfitter and often have to bring my phone along on trips. This bag has protected my phone and kept it dry, even when I swam a rapid and swam under waterfalls. Could not recommend this product enough. 10/10

Great
[This review was collected as part of a promotion.] Tested dry when I did water check. I used it while on a smoking trip. It worked great, used it with a water proof Fanny pack, stayed dry on the boat.

Passport protected!
[This review was collected as part of a promotion.] Did exactly what I needed protecting passport and other small travel documents on 10 day trek. Appreciated the multi fold and Velcro-like (better whatever it is) closure on top. Perfect size for passport.

The way the strap has
[This review was collected as part of a promotion.] The way the strap has to be secured to the bag doesn’t seem very secure to me. It’s not like it’s attached and sewn on.

Thin
[This review was collected as part of a promotion.] Thinner material than I expected. Time will tell if it develops a tear or not.

It's either defective, missing a piece, or poorly designed.
Got this case, size small as a Christmas gift. There are no instructions on how to use it, or videos on how to use it. It doesn't seal at all. It's too small to be really that useful either. I fold it over and attach the velcro tabs, but then it just unrolls itself. I think I could make it work with a pair of Gator clips (one on each side) to keep it from unrolling. You would think it should do that on its own with our having to add pieces to it. So yeah, thumbs down here. It not returnable, so I'm going to trash this one and go buy another brand. Good luck all.
