Thank you for viewing! This is a trekking bottle from Montbell, the "Alpine Thermo Bottle 0.35L (350ml)", which has excellent heat and cold retention properties. The color is a popular dark gray. It is brand new, unused, and comes with the original box. I received it as a prize at an event, but I have no use for it, so I am selling it. It is very lightweight and durable, and is a convenient size for use in the mountains, hiking, camping, and other outdoor activities, as well as for commuting to work or school. The simple design makes it easy to use for both men and women, and it is also recommended as a gift. 【Product Information】 ・Brand: mont-bell ・Model Name: Alpine Thermo Bottle 0.35L ・Capacity: 350ml ・Uses: Mountain climbing / Hiking / Commuting to work or school / Camping / Solo camping ・Condition: Brand new (with box) ・Color: Dark Gray ・Heat and cold retention compatible I will carefully pack and ship it.
