Big Agnes Seedhouse SL1 2009

The Big Agnes Seedhouse SL1 tent is freestanding, with a single hub-jointed pole system. This is simple to set up and throw the flysheet over to keep the rain off if you’re in a hurry. The first time I pitched it was in the dark with no instructions, and it looked fine in the morning. Inside there’s plenty of room for you and your gear, so it’s no hardship to sit out a shower before breaking camp. I can sit up at the door and cook in the porch, and there’s a pocket just above the door that is great for a tent light. The inner and outer doors are angled so you can open them, lie on your back and gaze straight up at the stars. It takes rough weather very well and has reflective guys and detailing for night-time safety. But the porch is not big enough for all my gear, so some goes inside (it’s only a big issue if the gear’s wet as there’s plenty of room). The fabrics are light and don’t have the best waterproofness, so long-term durability might be an issue. The all-mesh inner is cool in summer but cold in winter, and as it’s inner-pitched-first some may prefer others.

Verdict: The Big Agnes Seedhouse SL1 is a great lightweight tent with a strong design that’s easy to pitch while being comfortable. But it may not be ideal for the cold and wet British winter.
