Hydro Flask 40 oz Wide Mouth

A super durable, insulated water bottle that carries 40 fluid ounces (1.18L). When weight is a concern (i.e. long backpacking trips), I don’t take this along, but otherwise, it is with me wherever I go. Conditions:I’ve owned the Hydro Flask 40oz. Wide Mouth bottle for a year, using it to carry water for hiking trips, paddling trips, to the climbing gym, camping, and on road trips. Construction and Durability:The Hydro Flask 40oz Wide Mouth is a beast of a bottle. It’s made to last a lifetime… Full review

Hydro Flask 40 oz Wide Mouth

It looks great! This container is built to last forever, and looks fantastic. It keeps fluids fantastically warm, or cold. Now, the worst part of all, you can't hold it. I'm serious. This 40 oz., gorgeous bottle, appears to be powder coated on its outside finish. Have you ever tried to pick up, and hold, a full 40 oz. bottle that has a finish as slippery as a booger on a water slide? You can't, but I dare you to give it a try. Why Hydro didn't provide a porous outer shell, for a human hand to grip… Full review

Klean Kanteen 12oz Wide Insulated

Takes the prize for a pack-ready, sip-top insulted mug/bottle. The totally reliable seal opens with a twist, and the top disassembles easily for cleaning. Looks like it should take a lot of abuse. I am on a quest for the Holy Coffee Cup, and this one is getting pretty close. What I want is an insulated mug with a totally reliable seal that won't leak in my pack even if I take a 1,000-foot fall down a couloir, that can be opened for sipping with one mittened hand without having to find a place to… Full review

Avex Highland AUTOSEAL Stainless Travel Mug

While I love this product, I will never buy another Avex product because their customer service is worse than ZERO. I have bought more than 10 different Avex mugs since discovering them at the Outdoor Retailer show in Salt Lake City, and love them when they work. Then I had one ship with a defective lid before Christmas. I filed an online warranty request December 17 and have NEVER heard a word back other than the auto-reply that they would get back to me in 2-3 weeks. I've written two more times. Full review

Hydro Flask 40 oz Wide Mouth

Easily worth the purchase if you like to stay hydrated at home or work. It's a bit heavy for any kind of outdoor activity, but perfect to leave in the car for a nice cold or hot treat once you are back! I originally thought it was going to be too large, however, it's turned into my main water bottle during the day. It's easy to stay hydrated and Hydro Flask always stays cold or hot well longer than I anticipated. I have the grey color and it looks sharp! I've dropped it in a parking lot and just… Full review

Hydro Flask 18 oz Wide Mouth

Works well, but only when it works... I bought a Hydro Flask for the purpose of having a hot beverage with me on winter hikes. Initially, it worked well. My drinks were often so hot I could barely drink them. Less than one year after purchasing the Hydro Flask, I was up on Mt Jackson in 0 degree temps and the lid wouldn't open. I finally got it open and my drink seemed okay. I went to use it the next day on a long snowshoeing hike and when I tried to open it, it refused to open. My husband finally… Full review

Hydro Flask 32 oz Wide Mouth

The Hydro Flask 32 oz is an amazing product. I enjoy their marketing and the bright colors that they offer. Beyond the looks the functions of the wide mouth are perfect for all drink types. I enjoy that it comes in so many different styles. The best is the insulation is amazing because it has the capability to keep items extremely hot and ice drinks extremely cold. Full review

Hydro Flask 21 oz Standard Mouth

I bought this bottle, based on rave reviews and positive reports from others on social media...purchased for use primarily for taking hot coffee out on early morning canoe trips. It is a very nice bottle, but I have found it does much better at keeping beverages cold, than it does at maintaining hot beverages. I bought this particular size and shape of the Hydro Flask line, based on the description on the REI site. I often head out at 0500 for a few hours of canoeing, and it is nice to have hot… Full review
