What Our Gearhead(R) Experts Are Saying: "I've been using the Rift 10oz for daily espresso on the go and it's easily my favorite small tumbler. It fits perfectly under my coffee machine, seals tight in my pack, and doesn't leak a drop. The stainless steel build and removable silicone base make it feel tough yet refined-ideal for mornings at camp or on the commute."We love how the VSSL Rift Tumbler 10oz keeps our coffee ritual intact whether we're at home, on the trail, or cruising to the crag.
