Hydro Flask 40 oz Wide Mouth

Kinda wish I wouldn’t have spent $50 on it. I like it, but it doesn’t keep water cold unless you have ice. Which I hate, because why am I spending so much when I should’ve just purchased a regular bottle. Too late to return it, nothing I can do about it I know. I’m just telling people so they know before purchasing. If you drop it and it’s a far drop on accident on hard floor, street, rocks (hiking), etc. there will be 97% chance that there’s a dent in it. Sometimes big, sometimes little,… Full review

Stanley Adventure Vacuum Food Jar

A wide mouth, 0.5-liter thermos that can keep food palatably hot for up to 8 hours, but doesn't quite make it as a long-term ICDS (ice cream delivery system). A side mounted spork and secret compartment are some nice finishing touches.   Meet Fat Stanley I started making ice cream when I was 15, during the summers at my dad’s place in southern NH. I took an ice cream making hiatus during my college and world travel years, but after all that I put in a couple years as part-time caretaker and all-round… Full review

Primus TrailBreak Lunch Jug Large

Good to keep food warm for a few hours, do not expect insulation to equal a good water thermos. Recommended if you prep a hot meal in the morning to take for lunch. I bought it recently for a solo winter trip in the mountains I am planning, the idea being that I will cook in a large pot in the evenings, eat dinner, and save half for next day's lunch. This way I have a hot meal ready to stave off hypothermia if the temps drop abruptly in the night, and I save some fuel by cooking larger quantities. Full review

Stanley Classic Legendary Bottle

Sturdy but heavy vacuum flask. The Stanley Classic Legendary Bottle 0.47 litre vacuum flask. This vacuum flask (0.47 L / 16 oz) is rated to keep liquids hot or cold for 15 hours. I have not tested this: what I can say is that I have taken the flask on walks lasting six hours and it has kept my coffee hot throughout.   Stanley advertises its vacuum flasks as rugged and resistant to knocks. I have not tested this either (I like to take care of my gear). But I can believe it because the flask looks… Full review

Stanley Adventure Stainless Steel Vacuum Bottle 25oz

In those moments when a sip of hot tea helps you keep going and give a little more effort, that's when you appreciate having a good quality vacuum bottle and this Stanley meets all expectations. In some moments, we need that sip of hot drink that helps us to continue walking and with this vacuum bottle (25oz) we can be sure that our drink will stay warm, no matter what happens or the temperature at that moment. 1) Ease of Use: We just have to turn the lid and taste our hot drink. Something very… Full review

EcoVessel The Perk 20oz

I have tried a variety of insulated mugs for our travels but wanted this one for the removable strainer so I could enjoy loose leaf tea while traveling and for this, it works very well. Everything you need to know about this product is indicated in the pros and cons above! Full review

Klean Kanteen Insulated TKPro

The Insulated TKPro (25oz.) bottle from Klean Kanteen is everything an insulated bottle should be—durable to the max, well insulated, easy to pour, and comes with a comfortable cup. This bottle is a solid choice for those needing a solid insulated bottle. Conditions: I’ve used the 25 oz. Klean Kanteen Insulated TKPro (also comes in 16 oz. and 32 oz. options) for three months in the spring and summer, including during car camping adventures, a few fishing and deer scouting trips, and on a roadtrip.

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
