Hydro Flask 40 oz Wide Mouth Bottle
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
Stanley Classic Vacuum Bottle
Perfect for year around use, in town or country! A once in a lifetime investment!! Classic container! 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 Bottle
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 Bottle
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
SIGG Thermal Bottle 1.0 Liter
Have my 1L for about 10 years now and it still hold hot warm drinks for 24 hours, if you pre-warm it. Best for backpacking, mountaineering in cold weather. This 1L bottle weighs 522g being lighter than many other brands. It had a round bullet shape, that fits easily in inside backpacks without damaging plastic bags inside. Mine was made before the "Steelworks" sub brand, so I though it was made is Switzerland. Haven't had any problems inside it, such as ruptured liner, rust, etc. Used daily, as… Full review
Hydro Flask 12 oz Stainless Steel Vacuum Insulated Food Flask
Perfect addition for your camping trips! I bought this to go on my next camping trip. It was the perfect fit for food. I wanted something that was compact and before I got my 32 oz Hydro Flask I was able to test if this was able to keep to their marketing and keep all my food warm. Full review
Hydro Flask 32 oz Wide Mouth Bottle
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
