Bastante resistente, compacta y ligera. No tiene fugas y se puede guardar hasta en una sudadera por el tamaño.

Stylish and Reliable
The GSI Outdoors Boulder Flask Thermos is a fantastic companion for outdoor enthusiasts and travelers looking to enjoy their favorite beverages on the go. This flask has quickly become my go-to choice for its style, reliability, and impressive thermal performance. First and foremost, the design of the Boulder Flask is sleek and eye-catching. The durable stainless steel construction not only looks great but also ensures long-lasting durability. The textured grip adds a touch of elegance and provides a secure hold, preventing any accidental slips. When it comes to thermal performance, this flask truly shines. The double-wall vacuum insulation keeps my beverages hot or cold for extended periods. Whether I'm sipping on a steaming cup of coffee during a chilly hike or enjoying a refreshing cold drink on a hot summer day, the Boulder Flask consistently delivers on its promise. Another feature that sets this flask apart is its convenient size. With a generous 10-ounce capacity, it strikes the perfect balance between portability and capacity. It easily fits into my backpack or bag without taking up too much space, making it ideal for outdoor adventures or daily commutes. The leak-proof cap ensures worry-free transportation, preventing any spills or leaks. I appreciate the thoughtful design that allows for easy pouring and drinking, thanks to the well-designed spout and integrated cap.

Perfect!
Awesome flask! Seems durable and holds enough to get pretty darn tipsy. Lid seals tight. Pulling it out, unscrewing the lid, flipping the lid back and forth, and screwing the lid back on can be done one handed.

Great Flask with a minor but still kinda major flaw (BUT Fixable with a #14 "O" Ring Seal)
This is a great flask ONLY after purchasing seal separately. The Seal washed out when washing the 1st time. If you purchase, I would plan on buying this seal & making this a great flask without leaking being a worry. The seal is a #14 "O" Ring & around 1 Dollar. I purchased seal at my local Hardware store but I assume the big Home Improvement stores have these as well. I would highly recommend this flask after fixing this issue. Great size & cool design. Hope the plastic arm holds up over time. I will update this review if not.
