2025 Sunsets Collection, only NINE80 units produced

A friend, a sunset, and a perfectly cold (or warm, if that's your thing) drink is just about perfection. Our annual Sunsets Collection is our limited edition summer design voted on by our community. Always paired with our proprietary leak-proof lid, it's a first class ticket to summer fun (and no spills).

Alpine Dusk captures the dark mountain skies of summer, and the pink hues off the mountain range that are typical this time of year. Our kids call this 'cotton candy sky,' and this colorway is a special invitation to slow down and take in the alpine views. No snow required for après. 

Features:

  • Proprietary leak-proof, stainless steel lid with knurled edge.
  • Lid magnetically nests underneath while sipping.
  • Designed for on-the-go travel seekers and all-season enthusiasts
  • Vacuum insulation keeps drinks hot or cold for hours
  • 18/8 kitchen-grade stainless steel & dishwasher-safe design.

Just what I wanted

"I love this tumbler. I like drinking my beverages hot, but ride a bike or a bus to work. This tumbler allows me to brew my tea or coffee at home, chuck it bag, and drink it piping hot at work. The mouth is wide enough to fit a tea steeper, and the inner sip lid allows for nice big sips that don’t immediately scald your mouth, unlike other packable flasks. Precisely the product I’ve been waiting for!"

These tumblers are AWESOME! Such

"These tumblers are AWESOME! Such good quality, love the dedicated spot for the lid under the cup, & great options as well."

— Kaylee C. (5/5)

"Really interesting tumbler… it took us a couple minutes to wrap our heads around the lid system but when you get it, it’s amazing. It creates such a great seal, don’t twist it too tight - it doesn’t need it like other lids…. The self contained coaster is great and it keeps things hot OR cold for hours and hours. I would have given it five stars but I’m trying to cut out plastics… if it had less plastic, I’d definitely say it’s perfect."

— Robert (4/5)

Worse

"My shipment just been lost and delayed worst experience. Till now 8 days still no cup no update on shipment VSSL cup was at my door in 4 days. If you don't mind waiting like it's 1970 for your order then order away if not there other better cups that will be delivered in a more timely manner especially if we the customer are paying for shipping and handling. Feels like I just been ripped off cause now no one knows where the order is at. Contacted DHL and USPS no one knows."

— WOULD C. (1/5)

One more thing. . . . .

"I love this item on all accounts EXCEPT. . . . . the build is excellent, the colors are perfect and look nice in and understated way, the lids and the magnetic keep is a best in class, however the cup design is such that is does not fit into all cup holders. So the only thing I would change is the out diameter of the cup."

— MATTHEW R. (4/5)

"So far so good. Love the durability of the cup and it still fits in my vehicle cup holders which is a win. I like that I don’t have to worry about tipping it over or it spilling. The design is holding up flawlessly thus far. I have had it only 1 day but I can see this being my go to tumbler for years to come"

— SETH (5/5)

"These were at first superb items. They did an and still do, do an excellent job of insulating and keeping things cold or hot for an extended period of time. However, just had to take the silicone seals off one of my tumblers cuz it was getting mold behind it. Not a large issue in and of itself. What is to me an issue is the fact the seals are a split design that are extremely hard to clean. See the attached photo. Otherwise they are a great item. Why the seal is a split design is beyond me."

— Mr. (3/5)

Best tumbler in the market

"The Sherpa Tumbler is hands-down, the best Tumbler on the market. I had my doubts at first, thinking that this was just like any other drink vessel, but the intention behind its design will make you rethink using any other Tumbler from the moment you take your first sip. 10 out of 10 would highly recommend to anybody wanting to never have to buy another tumbler again."

— Charles B. (5/5)

Sturdy & Classy

"This product is truly remarkable. I had my name engraved on it. It’s holds hot beverages exceptionally well fir hours. In my opinion, the most appealing aspect of this product is its design and how sturdy it is-- sturdy and classy/elegant."

— Les A. (5/5)

These are as good as advertised!

"LOVE THIS. It is everything as advertised and will be a great new gifting item for my business. Also, their customer service is top notch. Elias has been so good in helping me see how I can add this to my strategic gifting line up."

— Hal C. (5/5)
