The Sea to Summit Explore ExIII Double is a super warm and roomy down sleeping Bag for 2. It's a versatile sleeping bag with plenty of venting options and can be turned into a conventional quilt.

Sea to Summit says:

Designed for those of us who love space, versatility and plush comfort, the Explore is ideal for outdoor adventures that return to the same camp site each evening, for car camping road trips, crag-hopping van life or hut-based expeditions.

Its spacious contoured rectangular shape, with an ultra-wide circumference, is ideal if you love freedom of movement and hate that tight sleeping bag feeling. And no matter which way the weather turns, the Explore can be modified to suit. Zip yourself in and pull the internal drawcords tight to combat the cold. When the temperature heats up, the multiple zips allow you to poke your toes out if you need a little fresh air or separate the top from the bottom of the bag and use it as a standalone quilt.

Vertical baffles over the chest section ensure the down insulation cannot migrate or shift to the outside of the bag during sleep, creating cold spots. A side block baffle construction maintains the 60/40 fill ratio, keeping more down on the top of the bag for maximum insulation.

The generous allocation of high quality 750+ Loft down ensures great insulation, while the oversized draft tubes prevents your body heat escaping. The panelled footbox and 3-dimensional hood make sure you're not compressing the down when you're trying to stay warm.

Designed to integrate with all our sleeping mats and to create the ultimate in sleep system comfort, the Explore utilises simple removable adjustable webbing loops to connect your mat to your bag.

Camping couples have not been forgotten - the four-season Explore ExIII is also available as a double for getting cosy under the covers with your favourite campsite companion. The mat attachment system on the double allows use of two single or one double mat and holds the mat secure under your Explore double bag.

If you want a roomy sleeping bag for 2 the Sea to Summit Explore ExIII Double Sleeping Bag will not disappoint. The wide contoured rectangular shape provides plenty of room. The 1000g of responsibly sourced dry treated down provides plenty of warmth.

The bag is packed with features to provide plenty of sleeping options. You have 2 way zips on both sides and a 2 way zip at the foot box. This array of zips allows plenty of venting options for when conditions are warm. The bag can be fully unzipped and turned into a conventional quilt. There are large baffles along the zips to retain heat and the large hood has 2 draw cord adjusters to get the fit right to keep the heat in when its cold.

The bag also comes with removable straps to keep the bag attached to your sleeping mat and stop the bag rolling over with you during the night. These straps can bve used on a double mat or 2 singles.
