>>694205>more waterproof>made of canvasSeriously.Any proper tent is to be considered 100% waterproof. If not, you should never even consider it.
Also, you can completely forget about canvas. Canvas is cotton. That shit is heavy and not waterproof unless very thick (causes the fabric to wet through and expand, thus "sealing" the fabric while itself is actually soaked). I have such a tent, and it is awesome. However, it weighs 12 kg (26 pounds), and sleeps 8 people -- hence, you only bring that fucker in a canoe or on a snowmobile...
What you want is a small, lightweight tent made in silnylon that is seam sealed from the factory.
If lightweight is an actual priority, you should look into what vendors like Big Agnes and Henry Shires' TarTent have to offer. Perhaps you could also give Helsport and Hilleberg a look.
You should under no circumstances consider a tent that weighs more than around 3 pounds: Don't forget that you actually have to carry it. If 2-3 person, you can give yourself some leeway on weight..
Pic related, Helsport's Ringstind Superlight 1-2 person tent. Comfy as fuck for one, sleeps two if needed, weighs less than one kg (<2 pounds).
