Sea to Summit Micro Series Sleeping Bag Watch video

The Sea to Summit Micro MC3 is the sleeping bag for the ultra-lightweight hiker or trekker, or cyclist tourist that are heading into crispy, cold yonder. Packing down to 5L in size, the MC3 will hardly make a dent to your pack or pannier, and with the regular length weighing in at a miniscule 710g you’ll hardly feel it on your back or in your legs.

The box quilted baffle construction and 850+ loft 95% European goose down ensures no cold spots to interrupt your sleep. The 55/45 fill ratio will keep your core insulated as you twist and turn in your sleep. The Nylon 2D NanoShell™ means breathability and moisture resistance to keep the down in top nick for years of adventures.  

Features a drawcord foot closure so you can flip between technical box foot mummy and open rectangular configuration, a zipped internal pocket for keeping your wallet, passport, or iGadget safe and warm, an anti-snag zip that actually works, and a lightweight Ultra-Sil® compression bag so small it might just get lost in your pack. The Micro MC3 is ideal for those needing a sleeping bag that is lightweight but also warm for those chilly adventures into the Australian or New Zealand Alps.

Oh no! I'm sorry to hear that Ruth. Sounds like we might've dropped the ball here, so if you have a sec, would you be able to give us a call on 1300 914 007. We'd like to make up for our blunder. Laine :)

Great compact bag

Packs down super small for such a warm sleeping bag, very impressed with the storage bag and quality of this item

Happy little camper

Amazing sleeping bag, warm and snug or open like doona for warmer nights. Packs down to nothing. Used it for 37 nights across the Pyrenees in the summer time but also had some cold wet mountainous nights.

Sea to summit Micro MC111

Extremely happy with its versatility especially in variable temperatures. The weight and size it packs down to is an added bonus


Down?1 answer

Just wondering if this version is made with Ultra-dry down, or if that's only the new versions?

G'day Matt, 

I've just checked this with the 2016 Sea to Summit Catalogue, and it states in there that the Micro bags are filled with Ultra-Dry Down.
