X-Mug Collapsible Mug

Forget the old "coffee in a water bottle" move when backpacking—you've got no reason to make do with what you've got when it's so easy to bring along the Sea To Summit X-Mug Collapsible Mug. This ultralight mug can be used for morning coffee, end of day hydration, and every meal in between. It's made with a food grade heat-resistant silicone that won't be damaged by hot camp meals, and also won't crack in the cold on chilly morning starts. It weighs less than three ounces and folds down flat in your pack, so you've got no reason not to bring it along to make your life a little easier in the backcountry.

Great travel cup!

[This review was collected as part of a promotion.] These cups are great for travel. We keep them in the pockets of our ski pockets so we don't have to use disposable cups in the lodge. The rims however do crack after many years of use and likely a few falls on the slopes ....

Would recommend!

[This review was collected as part of a promotion.] Very happy with the mug. Insulates enough that it doesn’t burn my hands. Lightweight and collapsible, taking up very little space in my pack. And it’s dishwasher safe, for ease of cleaning at home.

The Perfect Anytime Cup

[This review was collected as part of a promotion.] This is my second time buying this cup as my first one had an unfortunate knife encounter. I carry this cup in my purse so I am always ready for a drink--hot, cold, alcoholic, and not! It's slim, collapsible design, lightweight, and silicone make is perfect to fit in any bag and for any type of beverage. Everyone is always so impressed when I bring my own cup, I wish everyone could!

Great Customer Service

[This review was collected as part of a promotion.] My old STS X-mug was separating at the rim. I asked STS if they could fix it and they sent me a new one instead! Great customer service. The new model is slightly smaller but sturdier and I love it for backpacking. It fits inside my pot under the fuel canister perfectly.

Backcountry necessity!

[This review was collected as part of a promotion.] Comes with me on every overnight camping trip! Lightweight, packable, doesn’t scold hands when boiling water added, measuring cup is invaluable, and most importantly the vessel for my coffee! Love this cup!

S2S X Mug

[This review was collected as part of a promotion.] Purchased the X Mug for my Camper Van as storage is extremely small and it packs Perfectly! My sister and her fiance usually visit and needed extra drink ware for the upcoming fall season and spiked hot cider or cocoa! Easy use and cleaning makes it indispensable for spending time enjoying the outdoors, Van or Backpacking camping. I topped mine with a silicone lid to help keep my drinks cold/hot but mostly the critters! Highly Recommend
