MSR Hubba Hubba, 2 Person, Two Skin Tent
How about its four pound (1.8 kg) weight, with more than enough room for two? Or maybe it’s the freestanding, easy-pitch hub and pole system that sets up in a flash and is strong enough to handle the unpredictability of summer alpine conditions? Add 3 setup options, 2 full-size doors and vestibules, strong aluminum poles and factory-taped seams, and you’ll begin to understand why the Hubba Hubba tent remains the best selling Fast & Light® tent in the world.

Weighs 1890g / 4lbs 2oz assuming pegs supplied replaced with ultralight ones.

MSR Hubba Hubba HP, 2 Skin, 2 Person Tent - High Performance Version
The Hubba Hubba upgraded! The fly pitches closer to the ground and the inner tent is mainly solid fabric rather than mesh - so its warmer and sheds the weather more effectively.

Oh! - its also lighter than the classic version.
