Some flaws, but still worth it

The adjustable straps don't stay put when you cinch them down, which can get a little annoying. Cleaning is very easy though and I would still recommend this bottle.

I bought this bottle a few months back, took it on one short 6 mile run and felt like it was large/ bulky for being a handheld so I put it to the back of the shelf and hadn't thought about it til today - going out for a long run on the trails I thought it might help keep my liquid nutrition a little cooler than a different handheld, which. I mean let's be honest - a handheld can only stay cold for so long. Give it 30 min on a hot summer day and I bet any handheld you have is going to be Luke warm. But that's besides the point. The bottle works fine. But it's this ridiculous hand strap. It's a poor excuse for a retention system. I swear every 15-20 min I'd have to re-sinch it down. I found myself just grabbing the bottle instead of relying on the band taking the support up. This bottle would be fine for a waist pack, but just buy the one without the handstrap. Don't waste your time with this preposterous hand strap design. Love hydrapak - but I have great disdain towards this bottle in particular.

Great for Naked belt use

I picked this for two reasons, locking cap, and insulation. It does both just as expected, HydraPak stands behind products, so I have yet to unhappy over a purchase. Recommend.

Truly minimalist bottle

Good product but the strap is annoying because it keeps loosening.

Best Handheld Flask I’ve Used

This flask is amazing. No leaking, and you forget you’re holding it. I used it for a marathon. It worked great.

Great Concept But Poor Manufacturing Execution

The four-layer design is a great concept for preventing bottle sweat, but after only two weeks of use, liquids began leaking from the inside of the bottle to the outside layer resulting in liquid between the layers. I exchanged this bottle for the non-IT (non-insulated) version, the Skyflask 500 ml.

Best new hydration bottle yet

The SkyFlask is my new favourite Hydrapak hydration option! I love the feel, shape, size and function of this bottle. While I don't mind the flexible nature of most Hydrapak bottles, the insulation makes this one just a bit more sturdy so you can drink one handed -- which is awesome. I don't like an non-covered bite valve, so I just replaced the cap on this with Flat Cap and it works great!
