Good things come in the smallest packages.
The smallest, lightest sleeping bag from Sea To Summit, the featherweight and feather-stuffed—850+ fill to be precise—Micro McII Sleeping Bag 36 Degree Down provides lofty, three-season, ultra-portable warmth and weather protection. For treks, bike tours, or quick-and-dirty overnighters, this 36F-rated mummy will keep you dry with its Nano DWR coating and Ultra-Dry Down. Plus, the drawcord foot-opening frees your pinkies or converts the bag to a duvet.
- 36F lower EN rating, with a comfort rating of 45F, means the bag will keep you warm on cool late spring or early fall nights and during high-altitude summer trips
- Almost-magical Ultra-Dry Down 850+ European goose down repels moisture, retains loft, dries quickly, and fights bacteria and microbial growth for dry, fresh comfort
- Mummy shape with drawcord at foot opening allows use as a duvet in mild weather or when sharing or to liberate feet when they heat up
- Box-quilted with baffled, 55/45 fill-ratio to keep insulation evenly distributed to prevent cold or hot spots
- Regular length comfortably accommodates a person six feet tall
- High-density, downproof 2D Nano Shell 20D polyester weave with Nano DWR coating repels water at its durable exterior and the condensation on the inside to keep down dry, lofty, and quick-drying
- Super-soft, high-density, downproof 20D polyester weave lining breathes and feels luxurious next to skin for all-night comfort
- Hood drawcord with dual adjustment hugs your head with downy warmth
- Weighs a mere 1lb 3oz for ultimate portability
- Compresses in bag from 6 liters to 2 liters; you’ll be tempted to take it everywhere you go
- Large internal zippered pocket secures essentials at your side
- Includes Ultrasil compression stuff sack and mesh storage bag, and laundry bag for easy maintenance and convenience

Tiny, lightweight, but with limits
- Familiarity: I've used it once or twice and have initial impressions
So far, so good with this bag! It's crazy light, though an ounce or two heavier than the stated weight w/ the stuff sack (BC has the Reg size spec wrong at 1lb 3oz; STS's stated weight is 1lb 5oz; actual on my scale it's 1lb 6oz alone or 1lb 8oz in the stuff sack). Since my other bags are all a few ounces over their stated weights as well, I'm not too worried about this.
I've had it down to around 44-45F no problem, but I'm guessing it would get chilly near the rated 36F. Think of it as a great bag for desert camping in the 4 corners region. It stuffs down to about the size of a small melon. Frees up a ton of space in your pack. Also cool... when you undo the footbox and open the zipper, it makes a sweet duvet/quilt for warm nights. I'll update as I get more experience with it.
UPDATE: Still really like this bag, but returned it for a Mountain Hardwear Speed 32 (4F warmer, 6 oz lighter, compresses smaller, though maybe not as versatile). I'll miss the quilt feature of the STS, but my goal is lighter and more compact. I would still recommend the STS if size and weight isn't as much of a concern.
What is the difference between the Micro...
What is the difference between the Micro and Regular versions?
The micro is just the name of this series of sleeping bag so if you mean the Micro MC II and MC III the difference is the temp rating and weight.
if you mean between the micro series and the other Sea to Summit sleeping bags then there is a lot of differences. Finally if you mean the regular and long versions is the length, weight, and side the zipper is on.
