I love the See-to-Summit 14 ounce X-Mags, especially the bright colored ones. They are exceptionally versatile, we use them on picnics, when traveling and on the biking trips. Could not find them anywhere anymore and was glad, when "used" ones became available at half price. They were actually new.

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.

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!

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!

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

Excellent choice for ultralight thru hiking. Unfortunately my favorite mug developed a small hole and Sea to Summit replaced it promptly! What great customer service for an awesome product!

Also received my X-Mug, another fine product to accompany my X-Bowl. Both carried in my truck. Pack up small easy to use and always at the ready for my next adventure. Highly like this one, Yes would recommend this product as well.

I found the X-Series Mugs, Bowls, & Plates are really good for Base camp, Family/Car Camping or anywhere that space is a premium. They also clean easily and are very compact. Not sure yet, if I would use them for multi day backpacking due to being slightly heavier than a Ti Mug. The X-series does take heat well. I was eating oatmeal and soup from it daily for a month now. I gave it a 4 because of the weight, and It does seem to be picking up and retaining the smell and flavor of the soup. I have a different color for each of my kids so they don't fight over who's is who's.

This cup packs flat, so it is much more adaptable to backpacking. It weighs the same as my titanium mug, so it will be on my next trip.

Perfect size for morning coffee. I love that it collapsed small for storage. Also has measurements on the inside to help with meal prep and cooking. Must have for backpacking.

Love them. So much nicer and easier (no collapsing!) than the old metal cups I grew up using.

Stores away nicely, only thing is, heat goes through to hand, but I also Carry the paper heat cup holder and that helps the heat from coming through.

I really like the fact that these things collapse flat. Another thing, I didn't have ice cube trays on a trip where I brought a few of these and I used the x-mug to make a ice disk. sweet. Also this size is good for snacks or slasa.

A legit mug for cold or hot drinks. I have the bowl as well and am able to keep them together without taking up hardly any space. Just a smart design overall.

X MUG
By Denise R.
Took this on our AT thru hike. Held up very well and is insulated to hold a mug full of hot coffee, apple cider, or cocoa without burning your hands. It fits perfectly over my cook pot as a lid too!

The Summit mug is very lightweight and barely takes up bag space. With its two cup capacity, you get your fill of coffee or soda. The Sea To Summit X-Mug is a safe handheld cup, that allows you to enjoy all of your favorites in the wild.
