Full Review
TL;DR
- Who it’s for: Winter campers, bushcrafters, and duty use in sub‑zero conditions who value reliability in damp weather.
- Why it works: G‑LOFT® synthetic insulation retains loft when wet; a 3‑layer, differential‑cut build with Shellproof outer and center (mid) quick‑release zip keeps heat in and drafts out.
- Trade‑offs: 2.6 kg and 25×45 cm packed (≈22 L) make it bulky and heavy for mileage‑heavy trips. This is a true winter bag, not a do‑everything ultralight.
Carinthia Defence 6: What You’re Really Buying
The Defence 6 is Carinthia’s winter‑grade synthetic mummy built for reliable warmth below −10 °C. Unlike lightweight down bags, the G‑LOFT® fill keeps insulating if your shelter condenses or wets out. The center (mid) 2‑way zip with anti‑snag ribbon, inner draft tube, and outer storm flap simplifies venting and entry while preserving heat.
Stand‑outs in field use
- Heat retention: The 3‑layer sandwich with a loose outer shell and heat‑reflection insert noticeably slows radiant/convective loss when wind picks up.
- Usability: The quick‑release center zip is easy to locate with gloves and balances venting to both sides.
- Footbox: Trapezoidal cut avoids compression hot spots at the toes.
Warmth & Temperature Ratings (EN/ISO‑style)
- Limit: ≈ −18 °C (manufacturer comfort‑limit).
- Extreme: ≈ −40 °C (survival only; not a comfort rating).
- Expect variance by metabolism, shelter, and pad: pair with an R‑value ≥ 4.5 mat for best results around −10 to −15 °C. Cold sleepers should add a liner and a wind‑resistant bivvy.
Translation: If you’re routinely below −20 °C, consider stacking with additional layers or stepping to a dedicated expedition setup.
Build & Materials
- Insulation: G‑LOFT® (100% polyester) — resilient synthetic that lofts like down but handles moisture better.
- Shell & lining: Shellproof outer (polyamide/nylon) with microporous coating; Shelltrans inner lining (polyamide). Tough, snag‑resistant, and sheds drizzle/snow.
- Patterning: Differential cut prevents compression; neck baffle and zipper draft tube reduce heat loss.
- Zipper: 2‑way center zip with quick‑release pull, anti‑snag ribbon, and outer storm flap.
Weight, Pack Size & Carry
- Listed weight: ~2,600 g
- Pack size: ~25 × 45 cm (cylindrical ≈22 L) in the supplied compression sack.
- Reality check: This is not a compact bag. For long approaches, plan sled/ pulk or share shelter loads.
Fit, Sizing & Zip Options
- Dimensions: 230 × 87 × 60 cm (L × shoulders × foot).
- Sizes: M (to ~185 cm user height) and L (taller than 185 cm).
- Zip: Standard center (mid) zip; check variant at purchase.
Who Should Buy (and Who Should Skip)
Buy if you want:
- Winter‑credible warmth without babying a down fill
- A center‑zip synthetic that tolerates condensation and damp
- A rugged shell and glove‑friendly controls for field use
Skip if you need:
- Ultralight weight and small pack size for long alpine push days
- A mild‑weather 3‑season bag
Pros & Cons
Pros
- −18 °C limit warmth with synthetic resilience
- Center zip for balanced venting and quick egress
- Durable Shellproof outer resists abrasion and wetting
- Thoughtful details: neck baffle, anti‑snag ribbon, heat‑reflection insert
Cons
- Heavy/bulky vs. down or lighter synthetics
- Not the most breathable on warm shoulder‑season nights

Care & Longevity
- Air‑out after trips; store loose (not compressed).
- Spot‑clean as needed; for full wash, use a front‑loader, mild detergent, and low‑heat tumble with clean tennis balls to re‑loft.
- Avoid long‑term compression; synthetic loft still fatigues over time.
FAQ
Is it down‑filled?

Center zip or side zip?
The Defence series commonly uses a center (mid) zip with a quick‑release pull and inner draft tube.
How small does it pack?

Rating & Verdict
- Warmth vs. reliability: 4.8/5
- Comfort & features: 4.4/5
- Packability: 3.1/5
- Value: 4.2/5
Overall: 4.4/5 — If you need a proven winter synthetic that shrugs off condensation and keeps working in foul weather, the Defence 6 earns its reputation. If weight and pack size trump everything, look to lighter synthetics or expedition down.
