Snow Peak Titanium H300 Stacking Mug, TW-123, Premium Titanium, Made in Japan, Ultralight for Camping, Backpacking Everyday Use, Lifetime Product Guarantee

It's a virtually indestructible, eco minded, beautiful cup... it has already paid for itself with free coffee from generous hotel personnel, airline stewards etc. Everyone in the world should own one - just don't lose it! Also it's amazing the contrast between how hot it keeps the beverage and how normal the temperature is on the outside of the cup - I guess the magic is titanium with vacuum between. Incredibly light weight which seals the deal -- no excuse not to bring it with you. You won't regret it.

This is a wonderful mug! I bought it as a camping mug, but I've ended up using it as an everyday mug while overseas. It does a good job insulating liquids...the outside of my single walled Snow Peak mug tends to heat up very quickly (duh!), and the contents tend to cool off rather rapidly...this keeps my tea hot long enough for me to finish it leisurely while never getting so hot I can't pick it up. It does get toasty right after putting boiling water in, but not hot enough to burn me. It's also easier to drink from than the single walled mugs since the lip doesn't heat up quite so much. I do have a set of Hot Lips for my single walled mug, but they tend to fall off or get sandy/gritty when outdoors...I like not having to deal with that. Like the single walled titanium mug, you don't get a metallic taste when you drink, either. Finally, while I haven't eaten anything from it yet, I've drank water, tea, soju, and gatorade from it (and several combinations thereof), and all it's taken is a quick rinse with water to clean it out with no smell from the previous contents...As to construction, it's well made and very understated. The pictures on the Amazon website do it justice...the outside is smooth to the touch with just a hit of texture, while the inside has more texture, but is not rough. The only seam is on the rim weld where the outside meets the flared inner cup. They did a very good job of smoothing the weld line...it's uniform, small, and very smooth. Overall a fantastic, if slightly pricey mug for camping or everyday use. I haven't tried to actually crush it, but the outside is plenty stiff. It probably wouldn't stand up to dropping a 50 lb pack on it, but I don't foresee accidentally crushing it when it's packed. I'll definitely be checking out their other sizes!

nice mugs. not sure how they stack, but they are nice.

I now have these double-walled cups in both the 300mL and 450mL sizes. The 300mL nests perfectly inside the 450mL, but my uses for each don't require that. The 300mL goes with me in a coffee-brewing kit I take with me when I travel for work, even though I also use the cup for beer at the end of a day's work. A couple observations so far:- Coffee does stay warm longer, but there are better insulated options out there, if weight is not a concern.- Titanium is non-reactive, which means it doesn't affect the flavor of the drink you enjoy from it - whether coffee, beer, tea, water, etc. - unlike stainless steel, which can give you a metallic-y flavor to drinks.- (this is a weird one) Beer foams up more as you pour it into a titanium cup! I take one on backpacking trips at altitude, and at first I thought the beer foaming up was due to altitude. Nope. Even down at sea-level, I really have to pour slowly to minimize foaming.Overall, these cups are great, but pricey. Drinks stay warm longer (which is ESPECIALLY nice on backpacking trips where morning temps can be COLD!) in them, they're durable enough, and they're LIGHT!

I purchased the Snow Peak H450 cup after owning the small flask and being impressed with its high-quality manufacturing and attention to detail. I also purchased a Hydro Flask insulated mug, so I decided to do a side-by-side comparison to see how they stack up in terms of temperature retention.Temperature Retention Comparison (No Lids):I tested both cups by pouring 180°F water, heated with a Fellow kettle, and measured the temperature over 15 minutes. Here are the results:Snow Peak H450 (100.4g):• 5 mins: 155°F• 10 mins: 144°F• 15 mins: 135°FHydro Flask (269.4g):• 5 mins: 153°F• 10 mins: 145°F• 15 mins: 139°FAfter repeating the test a couple of times, the results were about the same. Without a lid, both cups perform similarly, though the Hydro Flask did slightly better in holding heat over time. When I used the Hydro Flask with its lid, the temperature only dropped to 165°F after 15 minutes, so a lid is definitely recommended for optimal performance, especially if you’re not drinking your hot beverage quickly.Handling & Comfort:The Snow Peak cup was pleasantly warm to the touch when filled, but never hot or uncomfortable to hold or touch to your lips. It was nice to sip from and warmed my hands slightly, which I appreciated—it’s a tactile reminder that you’re about to enjoy a hot drink. In contrast, the Hydro Flask’s exterior stayed cool, which can be deceiving when you forget just how hot the drink inside is.Design & Use:Aesthetically, the Snow Peak cup is beautiful, with a minimalist, functional design that weighs just 100 grams—perfect for camping or backpacking where every ounce matters. However, it doesn’t come with a lid, which is a downside for those who want to keep their beverage warm longer.The Hydro Flask, on the other hand, has a comfortable handle, soft plastic exterior coating, and comes with a lid. It’s slightly heavier but costs less and probably makes more sense for the average person looking for an insulated coffee mug.Final Thoughts:The Snow Peak H450 is an excellent choice for outdoor enthusiasts who value a lightweight, well-crafted cup, but keep in mind that a lid is almost essential for better heat retention. For everyday use, the Hydro Flask might be a more practical option with its included lid and similar performance at a lower price point.
