  • “48oz is huge. But I love the Snow Peak Titanium Kanpai coffee mug. Titanium doesn’t mess with taste, and it’s pretty bad-ass. Happy Father’s Day to all the fathers out there.”
  • “I mean sure yeah. But it’s also a cup that gets beat to shit if used as intended. Stuffed in the bottom of your pack, dangling to the side as you hike up mt rainier, scooping…”
  • “Same mug, same path. Just at 7 years old so far.”
