Common Questions
FAQs
Printing and sublimation apply ink on top of the surface — it degrades with washing, UV exposure, and daily use. Most printed bottles fade within 6–12 months. Laser engraving physically removes material from the stainless steel, creating a permanent mark that cannot fade, peel, or wash off. It survives dishwashers and daily use indefinitely.
UV printing uses ultraviolet light to cure ink directly onto the surface, producing vibrant full-color designs with gradients, photos, and complex artwork. Our 5D UV wrap technology curves the print seamlessly around the product. UV prints are durable and scratch-resistant (3–5+ years), while laser engraving is the most permanent option (lifetime). Choose engraving for permanence, UV for full-color impact.
Yes — every item in your order can have a unique engraving at no extra charge. This is perfect for team gifts where each person gets their name alongside the company logo. Just fill in names in the form or upload a spreadsheet.
Hand wash recommended to preserve the powder-coated finish and any UV printing long-term. The laser engraving itself is completely dishwasher-proof — it is etched into the steel and will never fade or degrade.

Six hours on the trail. A full day at the lake. A campout that goes until the stars come out.
Some days, 16 ounces isn't enough. You want to refill less. You want more cold between stops. You want the drink that lasts as long as the day does.
The Grouse 20oz is built for the long ones.
More Cold. More Volume. Same Dry Hands.
At 20oz, the Grouse holds enough for a full day of outdoor drinking without constant refills — and double-wall vacuum insulation means every ounce stays cold for 12 hours.
No condensation on the outside. No sweating through your hand, your pack, or the picnic table. The vacuum seal between two stainless walls means the cold stays inside, and the outside stays dry — no matter how warm the day gets.
Flip It Open. Drink Like It Was Meant to Be Drunk.
The leakproof flip-top lid opens wide — proper wide-mouth sipping, not a restricted straw port. You can smell the beer, taste the hops, drink the way it was meant to be drunk.
Closes fully for bag carry and trail transport. Flips open one-handed. No slider to jam with trail grit. Simple, solid, leakproof at any angle.
For a 20oz vessel, that matters. This is the tumbler you drink from without thinking about it.
Long Hike. Full Day. One Tumbler.
When the day is long enough that 16oz isn't enough, the 20oz Grouse carries you through. Camping trips. Full-day lake days. Tailgates that start in the afternoon and end after dark. Fishing from dawn to dusk.
Onyx or Snow — classic colors that go with everything and last forever. Powder-coated stainless steel, dishwasher safe, drop-proof. Built for the days that go long.
A Name. A Date. A Message. Permanent.
Laser-engraved by our team in Calgary — cut directly into the powder coat so you can feel every letter. Not a sticker. Not ink that fades. Permanent.
The 20oz Grouse is the go-to gift for the outdoor person who spends full days out. The guide. The hiker who goes before dawn. The person who's always the last one off the trail. Give them something with their name on it that actually lasts as long as they do.
Pick Onyx or Snow. Add their name or a short message. Ships in time for the trip.

Frequently Asked Questions
How long does it keep drinks cold?
12 hours cold, 6 hours hot. Same vacuum insulation as the 12oz and 16oz — just more volume. Fill it before a long hike and your last sip is as cold as your first.
Does it sweat / get condensation on the outside?
No. The vacuum insulation prevents the exterior from ever reaching the temperature of the drink inside. No condensation, dry hands, no rings on surfaces. Standard for the Grouse lineup.
What kind of lid does it have?
Same leakproof flip-top lid as the rest of the Grouse lineup. Closes fully for transport, flips open to a wide drinking opening. One-handed, no slider mechanism. Leakproof at any carry angle.
Who is the 20oz best for?
Anyone doing long days outdoors — full-day hikes, guided fishing trips, all-day lake days, multi-hour kayaking or paddling, long tailgates. The 16oz is great for most situations; the 20oz is for when you'd normally need to refill mid-activity and don't want to stop.
How does the free engraving work?
Add your engraving details during checkout. Your name, initials, date, or short message — laser-engraved into the powder coat. Permanent, dishwasher-proof, completely free with every tumbler.
Is it dishwasher safe?
Yes. Both the tumbler and lid are top-rack dishwasher safe. Laser engraving is engraved into the steel and never fades in the dishwasher.
How does it compare to YETI's 20oz option?
The YETI Rambler 20oz runs approximately $40 USD — roughly $55 CAD. The Grouse 20oz is $40 CAD, includes free laser engraving, and comes with a lifetime warranty. Same core insulation performance. Canadian price. Canadian-made.
