More Than Warmth — It’s Trust
The Motion Fleece Vest was made for those who love the chill of dawn,
for dogs that run ahead on misty trails and never stop exploring.
Every stitch, every test, and every field run is our promise —
that your dog can move, play, and adventure freely,
while staying warm in the cold wind.
Because warmth isn’t just about temperature —
it’s a way of saying:
“I’m ready to go.”
A truly effective mid-layer doesn't make a dog stop moving — it makes them keep going. The Motion Fleece Vest is the core of the PETT2GO layering system: maximum protection at the moment of greatest need, with minimum interference.
It Started with a Dog That Wouldn't Move
Last winter, owners kept asking PETT2GO: "Is there something warmer? My dog shivers through the whole walk."
We watched active dogs put on heavy winter coats and become still — unable to run, unable to chase, unable to be themselves. That observation became a question: what would it take to build a garment warm enough for the cold, but invisible enough for the sprint?
That question became the Motion Fleece Vest. After testing across fleece weights, weave structures, and stretch ratios, the answer was clear: warmth, stretch, and lightness don't have to trade off against each other. Achieving all three simultaneously just requires the right material engineering.
Warmth That Doesn't Ask Permission
Most dog winter garments fail in the same way: sufficient warmth, but at the cost of mobility, breathability, or post-activity thermal stability. The Motion Fleece Vest addresses all three simultaneously:
① Performance-Grade Anti-Static Fleece
Four-way stretch performance fleece with CLO 0.7–0.8 thermal retention value. In practical terms: this rating means that in a stationary 8°C environment, the vest alone maintains stable core temperature — without the weight or bulk of conventional knitwear. Lightweight and breathable during activity; consistently insulating when movement stops.
② Run-Free Cut™ — in the Mid Layer Too
The Motion Fleece Vest uses the same Run-Free Cut™ ergonomic pattern as PETT2GO's windbreaker and raincoat. Free-shoulder panel construction allows full forelimb extension; Balloon Cuff sleeve ends clear joint flexion points and seal against wind entry without restricting range of motion. Stride retention rate: 96% — the same standard applied to every garment in the line.
③ Engineered to Layer, Not Just to Wear
The vest's silhouette is specifically designed for layering. Low-profile fit adds insulation without bulk, and sits cleanly under a PETT2GO windbreaker or raincoat — so the two-piece system adds up to more than the sum of its parts, rather than two garments competing for the same space.
When the Motion Fleece Vest Is the Answer
| Conditions | Configuration | Why |
|---|---|---|
| Winter morning / evening walks (50–59°F / 10–15°C) | Vest standalone | Mild cold; vest provides sufficient core insulation |
| Cold wind or damp cold (46–54°F / 8–12°C) | Vest + Windbreaker | Layered system — insulation plus wind barrier |
| Cold rain or heavy rain below 46°F / 8°C | Vest + Raincoat | Maximum warmth and waterproof protection |
| Senior dog daily walks below 54°F / 12°C | Vest standalone or layered | 4-way stretch preserves joint mobility — non-negotiable for older dogs in the cold |
| Mountain overnight (after sunset) | Vest + Windbreaker (night) | Pack in the daypack; deploy at dusk when temperature drops |
Direct Skin Contact. Zero Compromise on Safety.
The Motion Fleece Vest sits directly against a dog's skin and coat. Every component passes:
- OEKO-TEX® STANDARD 100 — 1,000+ harmful substances tested and cleared, component by component: shell fabric, lining, thread, every fastener
- SGS & Intertek dual verification — independent third-party testing for physical performance (stretch, durability, colorfastness) and chemical safety
- CPSC compliance — meets U.S. Consumer Product Safety Commission standards for skin-contact products
The Motion Fleece Vest was built for dogs that love cold morning air — for the ones who are already investigating something three steps ahead of you before you've even looked up.
Every seam, every test, every iteration was made so they can keep doing exactly that. Ready to go. Always.
