Transport bottle review
We had just taken our first hike in midcoast Maine with our new transport bottle sling. Easy to use, easy to adjust, and extremely ergonomic. This has confirmed our choice.

Cautiously pleased
I own multiple Grayl filters along with several family members and rely on this product exclusively for my water supply while in the wilderness and traveling. I have zero complaints about those. My brother owns both a mission waist pack and a bottle sling as well. He has nothing but good to say. I haven’t used mine yet on an outing so I’m reserving judgement, however I’m afraid I may have ordered the wrong option fo the two - I wanted the double pockets for sure, and the carry handles on the transport are great, however there’s no real area to add some of the MODs to the bottle pouch itself, as I was hoping to add a multitool pouch. I may have to get the mission version instead. Overall though, it seems great!

I complained … you didn’t respond
I’ve bought a lot of Grayl kit - packs, pods, wallet, bottles are all great. The sling is not. It lacks Grayl’s burly denier quality & the attach point configuration is illogical - requiring multiple attach point being wasted as strap pivots to 2 dedicated loops for Velcro closures. The D rings & soft loops are useless as only one can be utilized as a result of the strap Velcro pivot. VERY disappointed.
